View 4 Replies View RelatedI wrote a C program using Pthreads to compute the product of 2 matrices. Each element in the product matrix is computed in a separate thread. Eg: Thread (i,j) computes the element C[i][j] of the matrix C, where C=A*B. A is m*n, B is n*p, C is m*p. m,n,p are given as command-line arguments. A and B are initialized to random values from 1 to 10, while all elements of C are initialized to -1.But some threads do not get their arguments (i,j) correctly. So some elements C[i][j] still remain as -1, even after the program is over. My OS is Ubuntu 10.10 (Maverick Meerkat) 32-bit.I ran the program on another computer and it worked correctly. Is it due to a problem in the Pthreads library in my OS? Please help me. I have attached the source code.
View 3 Replies View RelatedI have a webpage in html that uses <frameset> tag. One of the frames is a Table of Contents (toc.htm) that lists a series of images. The other frame is called 'canvas.htm'. My framset is laid out as follows:
<frameset rows="20%, 80%">
<frame src="./banner_sp.htm" ></frame>
<frameset cols="15, 85">
<frame name="toc" src="./toc.htm" ></frame>
[Code]....
The frameset is created properly and I can load the images manually (i.e. I can access the images from my browser and/or image editing tool). The problem comes when I attempt to access the images from the toc.htm frame. Instead of opening the image in the canvas.htm frame, a new window is displayed in my browser, instead of the image being displayed in the target window (canvas.htm). This happens on all of my browsers (firefox, safari, IE7/8 and Opera) on Windows, debian-linux and OS X 10.5/10.6.
If I change my src attribute (in the canvas frame) to toc.htm, I see the Table of Contents (toc.htm) displayed side-by-side until I click on the first drawing in the list. At this point, the frame 'behaves' half-arsed the way I want it to. I have searched on google till I am blue(er) in the face with no luck.
The code below prints garbage if I use puts() but it is fine if I use printf() instead (see sample of output at the bottom of this post). The odd thing is that the mess always starts after exactly eight properly printed characters. That sort of regularity can't be a coincidence, can it? It almost looks like an encoding issue (I'm using UTF-8) but if it really is, then I don't understand why the printf() is unaffected.
Code:
#include <stdio.h>
#include <string.h>
const char *nChars (const char *, int);
int main (int argc, char * argv[]){
char * name ="Count Dracula++";
int len = strlen(name);
if (argv[1] == 0) argv[1]="printf";
printf("--->%d characters", len); .....

I am busy writing this script to get a pixel count of a large batch of images in a directory for a research project. To do this I'm using a loop to get all the images in the directory. To make the whole procedure more user friendly for some colleagues I decided to use zenity, something I haven't yet really worked with. As not to make sure that the users don't have to watch to this blank screen during the actual processing of the images I'm trying to get the zenity progress bar working. So far the progress bar comes up but instead of changing over time it stays "empty" till all the images are processed and then becomes 100% when all images are done. What servers my needs for now, but since I am trying to learn more about zenity I was wondering how I could change the script to get the progress bar properly working? Below is the piece of script I am talking about.
Code:
cd $input #goto path of image directory
(for a in *jpg *JPG *jpeg *JPEG; do
if [ -f "$a" ]; then #was it a image file
b="$a" #set b to $a
convert -resize 1000x1000! ${b} -depth 1 -format %c histogram:info:$b.txt #get pixelcount and write to .txt file
fi
done) | zenity --progress

I have an user space application that performs file I/O operations, when a SIGKILL is captured, some routines are done first to ensure that all I/O operations are completed before rebooting the application or system. My question is, this won't work if the power button is pressed or the power supply is disconnected, so there can be incomplete I/O operation or corrupted data written into the file, so is there a way to prevent data corruption or at least complete any ongoing operation when this scenario happens? Assuming there is at most 1 second before the power really went out, can I/O be still completed?' I'm running the application on a busybox 2.6.14 kernel on an embedded system board.

I'm building a simple(?) socket server using threads to serve up a few requests. The spec is such that I have to listen to three ports at once, so I decided to use pthread to create three separate threads that would wait for connections, then spawn new threads to handle them.
The problem is that when I do this, for some reason the program never enters the wait loop and instead terminates (All three threads did get created since the messages get printed properly.) It gets to the line which prints "???", but not the line after the accept() call.I don't see an open port when I check for one either so I'm 99% sure they're terminating.Basically I have a main() method which has three calls to pthread_create, which should result in three threads being run that all wait for connections (listenOnPort). After each thread creation I print some info to make sure it's actually being created.
By the way, when I just run listenOnPortwithout threading, the server appears to enter the loop correctly and seems to be waiting for requests. It's only when I run the functions as threads that the problem seems to happen.The source is attached below. Any help will be appreciated. Much of the code is borrowed from a website (I can't post it because I am new here.) You need not worry about the handler_ methods because those are just methods that are run by the threads themselves.
Also--the original source was in C and I changed it to C++. Should I just use C?

So I need everything between each name, but I am not guaranteed that each time I match a name that I will have the same amount of lines, so I do a range pattern search line this to get all lines, no matter if there is 5 or 10 or 15. I simply do a loop that goes through the whole array until I hit the match, and this is my search pattern.
Code:
if ($LINE =~ /^s+$SELECTED_NAME/ ... $LINE =~ /(Address)/) {
push @ADDRESS_INFO, $LINE;
}
This works perfectly... until I hit the end and it doesn't get its final pattern match because it's at the end and there is no next entry with a (Address) line. So as a 'hack', I ended up inserting a final scalar at the end of the array that just says (Address) so it knows it's at the end. Ideally though, I'd like to do an "or" statement that says search for Address || return true if I hit the end of the array. How would I match on "End Of Array" essentially?
