• Not able to kill bad kernel running on NVIDIA GPU

  - by arvindkgs

  Hi, I am in a real fix. Please help. Its urgent. I have a host process that spawns multiple host(CPU) threads. These threads in turn call the CUDA kernel. These CUDA kernels are written by external users. So it might be bad kernels that enter infinite loop. In order to overcome this I have put a time-out of 2 mins that will kill the corresponding CPU thread. Will killing the CPU thread also kill the kernel running on the GPU? As far as what I have tested it does'nt. How can I also kill all the threads currently running in the GPU? Thanks, Arvind

• ajax call is looping indefinitely

  - by zurna

  I am pulling categories from an xml file. I only have 5 categories but the code below keeps pulling categories indifitely! Weird thing, I dont even have a loop in the xml function. Test link: http://www.refinethetaste.com/FLPM/ $.ajax({ dataType: "xml", url: "/FLPM/content/home/index.cs.asp?Process=ViewVCategories", success: function(xml) { $(xml).find('row').each(function(){ var id = $(this).attr('id'); var CategoryName = $(this).find('CategoryName'); $("<div class='tab fleft'><a href='http://www.refinethetaste.com/FLPM/content/home/index.cs.asp?Process=ViewVideos&CATEGORYID="+ id +"'>"+ CategoryName.text() + "</a></div>").appendTo("#VCategories"); CategoryName.find("div.row-title .red").tabs("div.panes > div"); }); } });

• how to keep the value of a variable in a closure

  - by Florian Fida

  i need to create multiple javascript functions which have a static id inside, so the function itself knows what data to process. Here is some code: (function(){ function log(s){ if(console && console.log) console.log(s); else alert(s); } var i = 10; while (i--){ window.setTimeout(function(){ // i need i to be 10, 9, 8... here not -1 log(i); },500); } })(); The problem ist that i allways gets updated by the loop, and i need to prevent this. Thanks in advance for any help, comments or tips!

• Code won't exit foreach block

  - by Matt

  I've got the following C# code segment that takes a list, finds objects that are ready to update, then shoves them into a temp list, deletes from the main list, and then goes on its merry way. My issue is that the foreach block, which cycles through my main list, won't exit. TempLog.Clear(); //Ensure TempLog is empty foreach (CLogger ready in PlayerLog) { if (ready.UpdateReady == true) // Record is ready to be updated in database { TempLog.Add(ready); // Add record to templog PlayerLog.Remove(ready); // Remove from playerlog } } <---- Never reaches this point if (TempLog.Count > 0) // Just check that templog isn't empty { new Thread(Update).Start(); // Run update code } I've put heaps of debugging in, and I can watch PlayerLog start at 1, TempLog at 0, then it enters the foreach loop, picks up that the record UpdateReady flag is on, TempLog goes to 1, PlayerLog goes to 0, then it just stops.. No errors, just stops.. Thanks for the help :)

• php foreach as variable

  - by user167850

  I'd like to use foreach to loop though an array list and add an element to each array. $tom = array('aa','bb','cc'); $sally = array('xx','yy','zz'); $myArrays = array('tom','sally'); foreach($myArrays as $arrayName) { ${$arrayName}[] = 'newElement'; } Is the use of ${$arrayName}[] the best way to do this? Is there another option rather than using curly braces? It currently works but I'm just wondering if there is a better alternative. Thanks

• [PHP] - Lowering script memory usage in a "big" file creation

  - by Riccardo

  Hi there people, it looks like I'm facing a typical memory outage problem when using a PHP script. The script, originally developed by another person, serves as an XML sitemap creator, and on large websites uses quite a lot of memory. I thought that the problem was related due to an algorithm holding data in memory until the job was done, but digging into the code I have discovered that the script works in this way: open file in output (will contain XML sitemap entries) in the loop: ---- for each entry to be added in sitemap, do fwrite close file end Although there are no huge arrays or variables being kept in memory, this technique uses a lot of memory. I thought that maybe PHP was buffering under the hood the fwrites and "flushing" data at the end of the script, so I have modified the code to close and open the file every Nth record, but the memory usage is still the same.... I'm debugging the script on my computer and watching memory usage: while script execution runs, memory allocation grows. Is there a particular technique to instruct PHP to free unsed memory, to force flushing buffers if any? Thanks

• Splitting a string with variable number of spaces VBA

  - by GVBA

  I have a file with a bunch of number in columns. These numbers are separated by variable number of spaces. I want to skip the first line and get all the other lines and separte each number on the line. Finally, I want to write each number on Excel. I've been able to get the lines and write them on Excel but I can't separate each number (I'm getting the whole line as one string). Does any body know how to split a string that has a variable number of spaces? Here is my code. Sub Test() r = 0 With New Scripting.FileSystemObject With .OpenTextFile("C:\Users\User\Desktop\File.tab", ForReading) If Not .AtEndOfStream Then .SkipLine Do Until .AtEndOfStream ActiveCell.Offset(r, 0) = Split(.ReadLine, vbCrLf) r = r + 1 Loop End With End With End Sub

• insert into several inheritance tables with OUTPUT - sql servr 2005

  - by csetzkorn

  Hi, I have a bunch of items – for simplicity reasons – a flat table with unique names seeded via bulk insert: create table #items ( ItemName NVARCHAR(255) ) The database has this structure: create table Statements ( Id INT IDENTITY NOT NULL, Version INT not null, FurtherDetails varchar(max) null, ProposalDateTime DATETIME null, UpdateDateTime DATETIME null, ProposerFk INT null, UpdaterFk INT null, primary key (Id) ) create table Item ( StatementFk INT not null, ItemName NVARCHAR(255) null, primary key (StatementFk) ) Here Item is a child of Statement (inheritance). I would like to insert items in #items using a set based approach (avoiding triggers and loops). Can this be achieved with OUTPUT in my scenario. A ‘loop based’ approach is just too slow where I use something like this: insert into Statements (Version, FurtherDetails, ProposalDateTime, UpdateDateTime, ProposerFk, UpdaterFk) VALUES (1, null, getdate(), getdate(), @user_id, @user_id) etc. This is a start for the OUTPUT based approach – but I am not sure whether this would work in my case as ItemName is only inserted into Item: insert into Statements ( Version, FurtherDetails, ProposalDateTime, UpdateDateTime, ProposerFk, UpdaterFk ) output inserted.Id ... ??? Thanks. Best wishes, Christian

• Explicit or implicit execution control statement use

  - by Andrei Rinea

  I sometimes use if (this._currentToolForeColor.HasValue) return this._currentToolForeColor.Value; else throw new InvalidOperationException(); other times I use if (this._currentToolForeColor.HasValue) return this._currentToolForeColor.Value; throw new InvalidOperationException(); The two are equivalent, I know, but I am not sure which is the best and why. This goes even further as you can use other execution-control statements such as brake or continue : while(something) { if(condition) { DoThis(); continue; } else break; } versus while(something) { if(condition) { DoThis(); continue; } break; } EDIT 1 : Yes the loop example(s) suck because they are synthetic (i.e.: made up for this question) unlike the first which is practical.

• Stack Overflow Accessing Large Vector

  - by cam

  I'm getting a stack overflow on the first iteration of this for loop for (int q = 0; q < SIZEN; q++) { cout<<nList[q]<<" "; } nList is a vector of type int with 376 items. The size of nList depends on a constant defined in the program. The program works for every value up to 376, then after 376 it stops working. Any thoughts?

• moving between states I get an error in Flex.

  - by Adam

  ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller. so i have a function that runs in state1 and has a while(myCanvas.rawChildren.numChildren > 0){ myCanvas.rawChildren.removeChildAt(0); } //this code is definitely the problem.... I can move to state2, but when I move back to state1 i get the error. why? the function that has the while loop only runs when something is searched in state1, so why is it running when coming back from state2?

• c#, can you think of anymore optimization in this code?

  - by Sha Le

  Hi All: Look at the following code: StringBuilder row = TemplateManager.GetRow("xyz"); // no control over this method StringBuilder rows = new StringBuilder(); foreach(Record r in records) { StringBuilder thisRow = new StringBuilder(row.ToString()); thisRow.Replace("%firstName%", r.FirstName) .Replace("%lastName%", r.LastName) // all other replacement goes here .Replace("%LastModifiedDate%", r.LastModifiedDate); //finally append row to rows rows.Append(thisRow); } Currently 3 StringBuilders and row.ToString() is inside a loop. Is there any room for further optimization here? Thanks a bunch. :-)

• Turing's Craft exercise stumped me... seems too easy.

  - by Chris

  "Write a for loop that prints the integers 1 through 40, separated by spaces or new lines. You may use only one variable, count which has already been declared as an integer." So I use... for(count = 1; count <= 40; count++) { cout << " " << count; } but they are using stdio.h as the only header and cout is not recognized. It hints that the output format should be (" ",count), but I can't figure out what print function to use. stdio.h can use fprintf or fwrite, but I don't have enough parameters for either function. Any ideas?

• Subtracting two lists in Python

  - by wich

  In Python, How can one subtract two non-unique, unordered lists? Say we have a = [0,1,2,1,0] and b = [0, 1, 1] I'd like to do something like c = a - b and have c be [2, 0] or [0, 2] order doesn't matter to me. This should throw an exception if a does not contain all elements in b. Note this is different from sets! I'm not interested in finding the difference of the sets of elements in a and b, I'm interested in the difference between the actual collections of elements in a and b. I can probably work this out with a for loop, looking up the first element of b in a and then removing the element from b and from a, etc. But this doesn't appeal to me, I'd like to do this with list comprehension in a nice and easy way. Is this possible?

• Removing object from NSMutableArray

  - by Ben Packard

  Just a small query... I stumbled across the following shortcut in setting up a for loop (shortcut compared to the textbook examples I have been using): for (Item *i in items){ ... } As opposed to the longer format: for (NSInteger i = 0; i < [items count]; i++){ ... } //think that's right If I'm using the shorter version, is there a way to remove the item currently being iterated over (ie 'i')? Or do I need to use the longer format?

• What is the best way to read files in an EventMachine-based app?

  - by Theo

  In order not to block the reactor I would like to read files asynchronously, but I've found no obvious way of doing it using EventMachine. I've tried a few different approaches, but none of them feels right: Just read the file, it'll block the reactor, but what the hell, it's not that slow (unless it's a big file, and then it definitely is). Open the file for reading and read a chunk on each tick (but how much to read? too much and it'll block the reactor, too little and reading will get slower than necessary). EM.popen('cat some/file', FileReader) feels really weird, but works better than the alternatives above. In combination with the LineAndTextProtocol it reads lines pretty swiftly. EM.attach, but I haven't found any examples of how to use it, and the only thing I've found on the mailing list is that it's deprecated in favour of… EM.watch, which I've found no examples of how to use for reading files. How do you read files within a EventMachine reactor loop?

• Deleting an element from an array in perl

  - by Flamewires

  Hey I'm wondering how i can get this code to work, basically i want to keep the lines of $filename as long as they contain the $user in the path. Sry, perl noob. open STDERR, ">/dev/null"; $filename=`find -H /home | grep $file`; @filenames = split(/\n/, $filename); for $i (@filenames) { if ($i =~ m/$user/) { #keep results } else { delete $i; # does not work. } } $filename = join ("\n", @filenames); close STDERR; I know you can delete like delete $array[index] but I don't have an index with this kind of loop that I know of.

• mySQL php query - news/ friends feed

  - by rpsep2

  I want to show a user the recent uploads from their friends. I have the users friends id's in an array: $friends A user could have, potentially, thousands of friends. I can select the uploads from 1 of a users friends with: $row = $mysqli->query("SELECT * FROM photos WHERE uploader_id = ".$friend." ORDER BY date_uploaded DESC LIMIT ".$page.", 25"); But I need to find all of a users friends uploads. I thought about doing this in a loop iterating over the $friends array, but then I'd be potentially running thousands of mysql queries. How can I do this most efficiently? so to clarify: search a 'photos' table for photos which are uploaded by specific users(friends), held in $friends variable, sort by date_uploaded and limit to x results so I can have pages 1, 2, 3 etc.

• problem in reading output of dd command using pipe

  - by Ummar

  I am developing an application, in which I want to redirect the output (progress information) of dd command to my C++ program, but it is not actually getting the output, here is the code FILE * progressInfo = popen("gzip -dc backup/backup.img.gz | pv -ptrbe -i 2 -s 2339876653 | dd of=/dev/sdb","r"); if(!progressInfo) { return -1; } char buf[1024]; while(fgets(buff, sizeof(buff),progressInfo)!=NULL) { std::cout << buff << endl; } but the problem is the progress information is not received in buff, and the output is continuously printed on terminal, and above program halts on while(fgets(buff, sizeof(buff),progressInfo)!=NULL), and as soon as the dd operation is completed, the very next line to loop block is executed. if anyone has any idea why the output is not returned to buff, and its continuously retuned on terminal?

• Insert objects into a collection with LINQ based on a property of the existing objects in the collection

  - by DavidS

  Hi, I've got a collection of object which contains data as follows: FromTime Duration 2010-12-28 24.0000 2010-12-29 24.0000 2010-12-30 24.0000 2010-12-31 22.0000 2011-01-02 1.9167 2011-01-03 24.0000 2011-01-04 24.0000 2011-01-05 24.0000 2011-01-06 24.0000 2011-01-07 22.0000 2011-01-09 1.9167 2011-01-10 24.0000 In the "FromTime" column, there are data "gaps" i.e. 2011-01-01 and 2011-01-08 are "missing". So what I'd like to do is to loop through a range of dates (in this instance 2010-12-28 to 2011-01-10) and "fill in" the "missing" data with a duration of 0. As I've just started with LINQ, I feel that it should be "fairly" easy but I can't quite get it right. I'm reading the book "LINQ in Action" but feel that I'm still quite a way off before I can resolve this particular issue. So any help would be much appreciated. David

• Process.WaitForExit not triggering with __debugbreak

  - by Cypher2100

  I'm trying to write a program to test student code against a good implementation. I have a C++ console app that will run one test at a time determined by the command line args and a C# .net forms app that calls the c++ app once for each test. The goal is to be able to detect not just pass/fail for each test, but also "infinite" (5secs) loop and exceptions (their code dying for whatever reason). The problem is that not all errors kill the C++ app. If they corrupt the heap the system calls __debugbreak which pops up a window saying Debug Error! HEAP CORRUPTION DETECTED... My C# app is using Process.WaitForExit(5000) to wait, but this error doesn't count as an exit, so I see a timeout. So my question is, how can I either get the C# app to detect that this is an error OR how can I get the C++ app to die when this error occurs rather than giving a dialog box and asking if I want to debug?

• Getting object coordinates from camera

  - by user566757

  I've implemented a camera in Java using a position vector and three direction vectors so I can use gluLookAt(); moving around in `ghost mode' works fine enough, but I want to add collision detection. I can't seem to figure out how to transform my position vector to coordinates in which OpenGL draws my objects. A rough sketch of my drawing loop is this: glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glLoadIdentity(); camera.setView(); drawer.drawTheScene(); I'm at a loss of how to proceed; looking at the ModelView matrix between calls and my position vector, I haven't found any kind of correlation.

• C++: Why does space always terminate a string when read?

  - by Nullw0rm

  Using type std::string to accept a sentence, for practise (I haven't worked with strings in C++ much) I'm checking if a character is a vowel or not. I got this: for(i = 0; i <= analyse.length(); i++) { if(analyse[i] == 'a' || analyse[i] == 'e' [..etc..]) { ...vowels++; } else { ... ...consenents++; } This works fine if the string is all one word, but the second I add a space (IE: aeio aatest) it will only count the first block and count the space as a consenent, and quit reading the sentence (exiting the for loop or something). Does a space count as no character == null? Or some oddity with std::string?, It would be helpful to know why that is happening!
