  • PC to USB transfer slow

    - by Vipin Ms
    I'm having trouble with USB transfer,not with external hard disk. Transfer starts with like, for the transfer of 700MB file it starts with 30mb/s and towards the end it stops at 0s and stays put for like 3-4 mins to transfer the last bit. I have tried different USB devices, but no luck. Is it a bug? Another important point is, in Kubuntu there is no such issue. So is it something related to Gnome? I'm using Ubuntu 11.10 64bit. Somebody please help, it's really annoying. Here are the details. PC all of my drives are in ext4. USB I tried ext3,ntfs and fat32. All having the same problem. Here are my USB controllers details: root@LAB:~# lspci|grep USB 00:1a.0 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #4 (rev 03) 00:1a.1 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #5 (rev 03) 00:1a.2 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #6 (rev 03) 00:1a.7 USB Controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #2 (rev 03) 00:1d.0 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #1 (rev 03) 00:1d.1 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #2 (rev 03) 00:1d.2 USB Controller: Intel Corporation 82801I (ICH9 Family) USB UHCI Controller #3 (rev 03) 00:1d.7 USB Controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 (rev 03) Here is an example of one transfer.

  • Optimising speeds in HDF5 using Pytables

    - by Sree Aurovindh
    The problem is with respect to the writing speed of the computer (10 * 32 bit machine) and the postgresql query performance.I will explain the scenario in detail. I have data about 80 Gb (along with approprite database indexes in place). I am trying to read it from Postgresql database and writing it into HDF5 using Pytables.I have 1 table and 5 variable arrays in one hdf5 file.The implementation of Hdf5 is not multithreaded or enabled for symmetric multi processing.I have rented about 10 computers for a day and trying to write them inorder to speed up my data handling. As for as the postgresql table is concerned the overall record size is 140 million and I have 5 primary- foreign key referring tables.I am not using joins as it is not scalable So for a single lookup i do 6 lookup without joins and write them into hdf5 format. For each lookup i do 6 inserts into each of the table and its corresponding arrays. The queries are really simple select * from x.train where tr_id=1 (primary key & indexed) select q_t from x.qt where q_id=2 (non-primary key but indexed) (similarly five queries) Each computer writes two hdf5 files and hence the total count comes around 20 files. Some Calculations and statistics: Total number of records : 14,37,00,000 Total number of records per file : 143700000/20 =71,85,000 The total number of records in each file : 71,85,000 * 5 = 3,59,25,000 Current Postgresql database config : My current Machine : 8GB RAM with i7 2nd generation Processor. I made changes to the following to postgresql configuration file : shared_buffers : 2 GB effective_cache_size : 4 GB Note on current performance: I have run it for about ten hours and the performance is as follows: The total number of records written for each file is about 6,21,000 * 5 = 31,05,000 The bottle neck is that i can only rent it for 10 hours per day (overnight) and if it processes in this speed it will take about 11 days which is too high for my experiments. Please suggest me on how to improve. Questions: 1. Should i use Symmetric multi processing on those desktops(it has 2 cores with about 2 GB of RAM).In that case what is suggested or prefereable? 2. If i change my postgresql configuration file and increase the RAM will it enhance my process. 3. Should i use multi threading.. In that case any links or pointers would be of great help Thanks Sree aurovindh V

  • Localization in php, best practice or approach?

    - by sree
    I am Localizing my php application. I have a dilemma on choosing best method to accomplish the same. Method 1: Currently am storing words to be localized in an array in a php file <?php $values = array ( 'welcome' => 'bienvenida' ); ?> I am using a function to extract and return each word according to requirement Method 2: Should I use a txt file that stores string of the same? <?php $welcome = 'bienvenida'; ?> My question is which is a better method, in terms of speed and effort to develop the same and why? Edit: I would like to know which method out of two is faster in responding and why would that be? also, any improvement on the above code would be appreciated!!

  • Should ATI catalyst be installed for sake of openCL?

    - by G Sree Teja Simha
    I have a HP Envy 4 1025tx with Hybrid graphics. Although this is a 64bit system, I've installed 32bit Ubuntu on it for some reasons.(Hybrid graphics don't do well with 64bit Ubuntu.-"Some one on some forum") I had heating problems with the GPU but I've fixed them all with vgaswitcheroo. But now I wanted to use my Blender on my Ubuntu. To my surprise Blender didn't detect the dedicated 7670m card in my machine. I've confirmed with cat /sys/kernel/debug/vgaswitcheroo/switch Both IGD and DIS were up and running. I dont seem to have libopencl on my /usr/lib even though my synaptic manager says that I have installed it. I'm not quite sure what I've installed. It says that I've installed "ocl-icd-libopencl1". So my question is... Do I have opencl on my system? If not do I have to get propreitary ATI drivers for sake of opencl(fglrx wrecks up my unity totally on my system I need directions to fix it if this is the choice)? Should I get a 64bit Ubuntu installed on this system?

What are the rules the crawler needs to follow etc. Basically anything info that makes the crawler look good and accurate. Just point me in a right direction to achieve it..

  • How to Iterate a Resharper Template ?.

    - by sree
    I have a small Resharper Template I have written for Null check of a function Parameter (C#). Check.IsNotNull($param$, "$param$"); - Suggest Parameter - #1 I can now null check the function paramters one by one. But I want to be able to null check all the paramters at once through a template. Is it Possible in Resharper?. Is there someting like a "$Foreach" using which I can loop through parameter variables and write the code to check them one by one ?. (without writing out the foreach into the code) I see that the "Alt + Ins" does something similar. (Taking all Properties on the class and making them as parameters of a constructor). So hoping that there's a way out.
