  • MySQL Server hitting 100% unexpectedly (Amazon AWS RDS)

    - by Luc
    Please help! We've been struggling with this one for months. This week we upped our RDS instance to the highest performing instance and although the occurrences have reduced, we're still having our DB all of a sudden hit 100%. It comes out of nowhere. Sometimes 2am, sometimes midday. I've ruled out a DOS - our pages access logs have normal traffic I've ruled out memcached suddenly dieing (hits and misses continue as normal). The SHOW PROCESSLIST while we have issues reports about 500 queries in queue. If I kill them off or restart the server, they just keep coming back and then eventually out of knowhere, our server resumes back to normal. Sometimes up to 3 hours. Our bad performing queries take .02 seconds to execute when the server eventually returns back to normal but while we're in this 100% CPU physco phase, those queries never finish executing. Please help!!!!! Anybody know anything about MYSQL query optimization? Could it be the server deciding to use different indexes all of a sudden, which puts it into a spiral?

  • HyperV - low CPU usage

    - by Klark
    I am very new to HyperV and virtual machine philosophy in general, so please expect more or less nooby questions :) I have a server that is only used as a host for virtual machines. OS is windows server 2008 R2 and it is running on 16 CPU and 48 GBs of RAM. On aforementioned server there are 8 VMs, each having 4 CPUs and 4 GBs of RAM. On those VMs we are running some CPU intensive tasks. Each machine has nearly 100% cpu usage. After I noticed slow performance I went to the host machine and started playing with process explorer. It turned out that cpu usage is very low. Also I/O is very low, and of course, memory consumption is high, which is expected. Of course, I don't expect that those 4 virtual cores dedicated to a VM work as fast as real, hardware 4 cores, but still I expected a higher consumption of real hardware. Is this sort of behaviour normal? I see that the most of CPU usage on host machine are marked as interrupts (which I guess is normal) and all those interrupts are passed to only one core (which is strange). Are there out of box optimization that I could perform to finally use all that processing power that is under the hood. My knowledge of virtualization technology is near to embarrassing, so I would be grateful for any links that could enlightened me :) Thanks.

  • Folder redirection GPO doesn't seem to be working

    - by homli322
    I've been trying to set up roaming profiles and folder redirection, but have hit a bit of a snag with the latter. This is exactly what I've done so far: (I have OU permissions and GPO permissions over my division's OU.) Created a group called Roaming-Users in the OU 'Groups' Added a single user (testuser) to the group Using the Group Policy Management tool (via RSAT on Windows 7) I right-clicked on the Groups OU and selected 'Create a GPO in this domain, and Link it here' Added my 'Roaming-Users' group to the Security Filtering section of the policy. Added the Folder Redirection option, specifically for Documents. It is set to redirect to: \myserver\Homes$\%USERNAME%\Documents (Homes$ exists and is sharing-enabled). Right-clicked on the policy under the Groups OU and checked Enforced. Logged into a machine as testuser successfully. Created a simple text file, saved some gibberish, logged off. Remoted into the server with Homes$ on it, noticed that the directory Homes$\testuser was created, but was empty. No text file to be found. From what I've read, I did everything I aught to...but I can't quite figure out the issue. I had no errors when I logged off about syncing issues (offline files is enabled) or anything, so I can only imagine my file should have ended up up on the share. Any ideas? EDIT: Using gpresult /R, I confirmed the user is in fact part of the Roaming-Users group, but does not have the policy applied, if that helps. EDIT 2: Apparently you can't apply GPOs to groups...so I applied to users and used the same security filter to limit it to my test user. Nothing happens as far as redirection goes, but I now have the following error in the event log: Folder redirection policy application has been delayed until the next logon because the group policy logon optimization is in effect

  • Why is my apache2, mod_fcgid, php configuration causing 100% cpu usage?

    - by Scott Lundgren
    Page load makes a quick initial connection, then hangs about 10 seconds before the page renders. When the server load goes up I start watching top & I see that both CPUs get pegged at times to 100% by between 4-8 processes of php-cgi. My theory is that since I never see RAM usage never go above 50%, that apache is able to handle the requests coming in, but is queueing them for PHP to process. What is wrong with my mod_fcgid/php configuration ?

  • What are these CPU cache settings? Snoop Filter, ACL prefetch, HW prefetch

    - by eater
    I was in my BIOS setup turning on VT-x support today and saw these other settings. A little googling indicates that they each seem to turn on some sort of optimization to do with the CPU's L2 cache. They were all turned off by default. The processor in question is an Intel Xeon quad-core 3.4GHz (X5492). My OS is Linux 2.6.35.10-74.fc14.x86_64 #1 SMP Thu Dec 23 16:04:50 UTC 2010 x86_64 x86_64 x86_64 GNU/Linux. I have 4GB of RAM if that matters. Here's what the BIOS manufacturer has to say: Snoop Filter Enabling the snoop filter typically improves performance by reducing snoop traffic on the frontside bus in dual processor configurations. Well I like the sound of improved performance. Why would the BIOS have this off by default? Or by dual processor do they not mean multi-core? Regardless, is there a downside if this is on? ACL Prefetch When enabled, the Adjacent Cache Line Prefetcher fetches both cache lines that comprise a cache line pair when it determines required data is not currently in its cache. When disabled, the processor will only fetch the cache line required by the processor. HW Prefetch Fetches an extra line of data into L2 from external memory. Both of these sound like optimizations that have some drawbacks. What are the reasons to turn them on? What are the reasons to leave them off. Why is the default off?

  • To what extent is size a factor in SSD performance?

    - by artif
    To what extent is the size of an SSD a factor in its performance? In my mind, correct me if I'm wrong, a bigger SSD should be, everything else being equal, faster than a smaller one. A bigger SSD would have more erase blocks and thus more leeway for the FTL (flash translation layer) to do garbage collection optimization. Also there would be more time before TRIM became necessary. I see on Wikipedia that it remarks that "The performance of the SSD can scale with the number of parallel NAND flash chips used in the device" so it seems throughput also increases significantly. Also many SSDs contain internal caches of some sort and presumably those caches are larger for correspondingly large SSDs. But supposing this effect exists, I would like a quantitative analysis. Does throughput increase linearly? How much is garbage collection impacted, if at all? Does latency stay the same? And so on. Would the performance of a 8 GB SSD be significantly different from, for example, an 80 GB SSD assuming both used high quality chips, controllers, etc? Are there any resources (webpages, research papers, presentations, books, etc) that discuss correlations between SSD performance (4 KB random write speed, latency, maximum sequential throughput, etc) and size? I realize this does not really sound like a programming question but it is relevant for what I'm working on (using flash for caching hard drive data) which does involve programming. If there is a better place to ask this question, eg a more hardware oriented site, what would that be? Something like the equivalent of stack overflow (or perhaps a forum) for in-depth questions on hardware interfaces, internals, etc would be appreciated.

  • What is a suitable simple, open web server for Windows?

    - by alficles
    I'm looking for a dead simple web server for Windows. Load will not be high as it will be primarily serving binaries for a WPKG update service. It needs to serve the entire contents of a single folder over HTTP on a configurable (high) port. No CGI or other scripting is required, but it might be nice for future features. I started with Mongoose, since it doesn't even have an installation requirement (a very nice perk), but it fails to start when run as a service. (Technically, it acts as it's own installer.) I've investigated LighTPD as well, but it appears to be minimally (at best) tested on Windows. And naturally, I'm looking for something free. As in beer is good, but speech is better, as always. Edit: I didn't mention this initially, but non-tech people will be doing the install. They'll have whatever script I write for the install, but the goal is a simple system that is easy to troubleshoot. (I almost worded this question "What is the best...", but Serverfault rightly observed that that is a subjective question. And it's really not an optimization problem, any suitable solution will work. I just can't seem to find one for Windows.)

  • i7-980X at 70% speed

    - by Buxley
    Hi we bought a nice computer to use to solve optimization problems. Intel i7-980X@3,33 GHz with 12 GB of Team Group 1600 MHz DDR3 RAM. When we use Gurobi the computer uses all 12 cores at maximum in the beginning of the solve. However after a while (about 8 hrs) it all cores jump between 65 and 85% When I solve the same models on an i7 930 all cores are at a near 100% level even after longer solution times. We first thought that the Hard disk was the bottleneck since Gurobi writes out nodefiles after the memorylimit is used. However since the new computer have 12 GB of RAM we put the memorylimit to 7 GB so the solver only used the RAM and still with the same performance in the processor. Any ideas about the bottleneck? As I said earlier it works at 100% for the first hours or so . Thanks very much for any answers! Our plan was to overclock it but we can't even get it to work at normal speed yet!

  • Low-traffic WordPress website on Apache keeps crashing server

    - by OC2PS
    I have recently moved my low-moderate traffic (1000 UAUs, 5000 pageviews on a busy day) website from shared hosting to a Centos 6 64-bit VPS with Apache and cPanel running on 4 quad-core processor (likely oversold) and 3GB memory (Xen). We've had problems from the beginning. The server keeps crashing. It seems PHP keeps expanding till it consumes all the memory and crashes the server. Some folks have suggested that I should abandon Apache/cPanel/PHP/mySQL and go with nginX/Varnish/PHP-FPM/SQLite. But that's just not possible for me as I am not very tech savvy and need a simple GUI like cPanel to be able to manage the mundane management tasks (can't afford to hire system administrator or get fully managed hosting). I have come across several posts discussing optimization of Apache for WordPress. But all of these lead to articles that are pretty dated such as this ~4 year old one from Jan 2009 - http://thethemefoundry.com/blog/optimize-apache-wordpress/ The article is pretty detailed and seems helpful, but I stumble even on the first step. My httpd.conf only has 2 loadmodule commands LoadModule fastinclude_module modules/mod_fastinclude.so LoadModule bwlimited_module modules/mod_bwlimited.so So I go total bust right there. Further, my httpd.conf says Direct modifications to the Apache configuration file may be lost upon subsequent regeneration of the configuration file. To have modifications retained, all modifications must be checked into the configuration system by running: /usr/local/cpanel/bin/apache_conf_distiller I am having trouble finding where to change the modules in WHM. Please can someone help me with updated guidelines on how to optimize Apache for WordPress? Many thanks! P.S. The WordPress installation also has WP Super Cache installed. P.P.S. I also have phpBB, OpenCart, and Menalto Gallery installed.

  • MySQL : table organisation for very large sets with high update frequency

    - by Remiz
    I'm facing a dilemma in the choice of my MySQL schema application. So before I start here is a picture extremely simplified of my database : Schema here : http://i43.tinypic.com/2wp5lxz.png In one sentence : for each customer, the application harvest text data and attached tags to each data collected. As approximation of the usage of each table, here is what I expect : customer : ~5000, shouldn't grow fast data : 5 millions per customer, could double or triple for big customers. tag : ~1000, quite fixed size data_tag : hundred of millions per customer easily. Each data can be tagged a lot. The harvesting process is permanent, that means that around every 15 minutes new data come and are tagged, that require a very constant index refreshing. A lot of my queries are a SELECT COUNT of DATA between specific DATES and tagged with a specific TAG on a specific CUSTOMER (very rarely it will involve several customers). Here is the situation, you can imagine with this kind of volume of data I'm facing a challenge in term of data organization and indexing. Again, it's a very minimalistic and simplified version of my structure. My question is, is it better: to stick with this model and to manage crazy index optimization ? (which involves potentially having billions of rows in the data_tag table) change the schema and use one data table and one data_tag table per customer ? (which involves having 5000 tables on my database) I'm running all of this on a MySQL 5.0 dedicated server (quad-core, 8Go of ram) replicated. I only use InnoDB, I also have another server that run Sphinx. So knowing all of this, I can't wait to hear your opinion about this. Thanks.

  • DES3 decryption in Ruby on Rails

    - by AntonAL
    My RoR server receives a string, that was encrypted in C++ application using des3 with base64 encoding The cipher object is created so: cipher = OpenSSL::Cipher::Cipher::new("des3") cipher.key = key_str cipher.iv = iv_str key_str and iv_str: are string representations of key and initialization vector for encryption algorithm. They are the same for RoR and C++ application. The code on the RoR side is following: result = "" result << cipher.update( Base64.decode64(message) ) result << cipher.final After executing the last line of code, i get an exception OpenSSL::CipherError (bad decrypt) What is wrong here ? Any ideas ?

  • How to convert DATETIME to FILETIME value in T-SQL?

    - by Alek Davis
    I need to convert a SQL Server DATETIME value to FILETIME in a T-SQL SELECT statement (on SQL Server 2000). Is there a built-in function to do this? If not, can someone help me figure out how to implement this conversion routine as a UDF (or just plain Transact-SQL)? Here is what I know: FILETIME is 64-bit value representing the number of 100-nanosecond intervals since January 1, 1601 (UTC) (per MSDN: FILETIME Structure). SQL Server time era starts on 1900-01-01 00:00:00 (per SELECT CAST(0 as DATETIME). I found several examples showing how to convert FILETIME values to T-SQL DATETIME (I'm not 100% sure they are accurate, though), but could not find anything about reverse conversion. Even the general idea (or algorithm) would help.

  • Is Programming == Math?

    - by moffdub
    I've heard many times that all programming is really a subset of math. Some suggest that OO, at its roots, is mathematically based. I don't get the connection. Aside from some obvious examples: using induction to prove a recursive algorithm formal correctness proofs functional languages lambda calculus asymptotic complexity DFAs, NFAs, Turing Machines, and theoretical computation in general the fact that everything on the box is binary In what ways is programming really a subset of math? I'm looking for an explanation that might have relevance to enterprise/OO development (if there is a strong enough connection, that is). Thanks in advance. Edit: as I stated in a comment to an answer, math is uber important to programming, but what I struggle with is the "subset" argument.

  • Drawing a clamped uniform cubic B-spline using Cairo

    - by Tamás
    I have a bunch of coordinates which are the control points of a clamped uniform cubic B-spline on the 2D plane. I would like to draw this curve using Cairo calls (in Python, using Cairo's Python bindings), but as far as I know, Cairo supports Bézier curves only. I also know that the segments of a B-spline between two control points can be drawn using Bézier curves, but I can't find the exact formulae anywhere. Given the coordinates of the control points, how can I derive the control points of the corresponding Bézier curves? Is there any efficient algorithm for that?

  • Generating a KML heatmap from given data set of [lat, lon, density]

    - by Will Croft
    I am looking to build a static KML (Google Earth markup) file which displays a heatmap-style rendering of a few given data sets in the form of [lat, lon, density] tuples. A very straightforward data set I have is for population density. My requirements are: must be able to feed in data for a given lat, lon must be able to specific the given density of the data at that lat, lon must export to KML The requirements are language agnostic for this project as I will be generating these files offline in order to build the KML used elsewhere. I have looked at a few projects, most notably heatmap.py, which is a port of gheat in Python with KML export. I have hit a brick wall in the sense that the projects I have found to date all rely on building the heatmap from the density of [lat, lon] points fed into the algorithm. If I am missing an obvious way to adapt my data set to feed in just the [lat, lon] tuples but adjusting how I feed them using the density values I have, I would love to know!

  • Matlab 3d volume visualization and 3d overlay

    - by inf.ig.sh
    Hi, so the question ist pretty much the title. I have a 3d volume loaded as raw data [256, 256, 256] = size(A). It contains only values of zero's and ones, where the 1's represent the structure and 0's the "air". I want to visualize the structure in matlab and then run an algorithm on it and put an overlay on it, let's say in the color red. So to be more precise: How do i visualize the 3d volume. 0's transparent, 1's semitransparent? Plot a line in the 3 d vis as an overlay? I already read the mathworks tutorials and they didn't help. I tried using the set command, but it fails completly saying for every property i try "invalid root property". I hope someone can help.

  • Design for a machine learning artificial intelligence framework

    - by Lirik
    This is a community wiki which aims to provide a good design for a machine learning/artificial intelligence framework (ML/AI framework). Please contribute to the design of a language-agnostic framework which would allow multiple ML/AI algorithms to be plugged into a single framework which: runs the algorithms with a user-specified data set. facilitates learning, qualification, and classification. allows users to easily plug in new algorithms. can aggregate or create an ensemble of the existing algorithms. can save/load the progress of the algorithm (i.e. save the network and weights of a neural network, save the tree of a decision tree, etc.). What is a good design for this sort of ML/AI framework?

  • Translation of clustering problem to graph theory language

    - by honk
    I have a rectangular planar grid, with each cell assigned some integer weight. I am looking for an algorithm to identify clusters of 3 to 6 adjacent cells with higher-than-average weight. These blobs should have approximately circular shape. For my case the average weight of the cells not containing a cluster is around 6, and that for cells containing a cluster is around 6+4, i.e. there is a "background weight" somewhere around 6. The weights fluctuate with a Poisson statistic. For small background greedy or seeded algorithms perform pretty well, but this breaks down if my cluster cells have weights close to fluctuations in the background. Also, I cannot do a brute-force search looping through all possible setups because my grid is large (something like 1000x1000). I have the impression there might exist ways to tackle this in graph theory. I heard of vertex-covers and cliques, but am not sure how to best translate my problem into their language.

  • Sorting eigenvectors by their eigenvalues (associated sorting)

    - by fbrereto
    I have an unsorted vector of eigenvalues and a related matrix of eigenvectors. I'd like to sort the columns of the matrix with respect to the sorted set of eigenvalues. (e.g., if eigenvalue[3] moves to eigenvalue[2], I want column 3 of the eigenvector matrix to move over to column 2.) I know I can sort the eigenvalues in O(N log N) via std::sort. Without rolling my own sorting algorithm, how do I make sure the matrix's columns (the associated eigenvectors) follow along with their eigenvalues as the latter are sorted?

  • Why aren't we programming on the GPU???

    - by Chris
    So I finally took the time to learn CUDA and get it installed and configured on my computer and I have to say, I'm quite impressed! Here's how it does rendering the Mandelbrot set at 1280 x 678 pixels on my home PC with a Q6600 and a GeForce 8800GTS (max of 1000 iterations): Maxing out all 4 CPU cores with OpenMP: 2.23 fps Running the same algorithm on my GPU: 104.7 fps And here's how fast I got it to render the whole set at 8192 x 8192 with a max of 1000 iterations: Serial implemetation on my home PC: 81.2 seconds All 4 CPU cores on my home PC (OpenMP): 24.5 seconds 32 processors on my school's super computer (MPI with master-worker): 1.92 seconds My home GPU (CUDA): 0.310 seconds 4 GPUs on my school's super computer (CUDA with static domain decomposition): 0.0547 seconds So here's my question - if we can get such huge speedups by programming the GPU instead of the CPU, why is nobody doing it??? I can think of so many things we could speed up like this, and yet I don't know of many commercial apps that are actually doing it. Also, what kinds of other speedups have you seen by offloading your computations to the GPU?

  • Text mining with PHP

    - by garyc40
    Hi, I'm doing a project for a college class I'm taking. I'm using PHP to build a simple web app that classify tweets as "positive" (or happy) and "negative" (or sad) based on a set of dictionaries. The algorithm I'm thinking of right now is Naive Bayes classifier or decision tree. However, I can't find any PHP library that helps me do some serious language processing. Python has NLTK (http://www.nltk.org). Is there anything like that for PHP? I'm planning to use WEKA as the back end of the web app (by calling Weka in command line from within PHP), but it doesn't seem that efficient. Do you have any idea what I should use for this project? Or should I just switch to Python? Thanks
