1- Is reviewing hardware that you have posted in the HCL considered 'bad form'?
2- Is it good, bad or indifferent to put up hardware that is not currently avaible? I've got several older computers, and I'm more than happy to put them up. I'd assume that its encouraged to do so, but seeing how I was going to ask the other question I thought there is no harm in asking.
I checked a couple of locations:[URL]... and none of the files listing checksums do so for the LiveCD ISO neither md5 nor sha1. Being a "trust but verify" sort of fellow. . .

When I tried Karmic, it would only boot with Safe Graphics (everything else hangs the system), but nothing is ever displayed. I hear the Ubuntu start-up sound but the display stays blank. Does anyone have any advice on installing Ubuntu on this system?

View 5 Replies View RelatedI have a script that basically takes a list of IP addresses, and pings them to tell me if each device (Access Point) is online or not. The problem with that is, the list contains about a hundred addresses. Making the problem worse is the fact that using a single ICMP packet per device is not an option since, at certain times of the day, the network is too congested to guarantee that a single ICMP packet won't be dropped, despite the device being up and running. That means I need to send multiple pings per device for about a hundred devices. As you can imagine, doing this sequentially takes a while.
What I want to do is make my script open other threads in the background to ping multiple devices in parallel. The problem with that is - if I simply make each ping command run in parallel, soon there are a hundred background tasks, one for each address, and that consumes a lot of CPU (CPU hits 100% and stays there till the script is done). Is there a way I can make about 10 threads run at a time, and any other threads will queue until a spot opens up for them? Kind of like the token bucket, except when there aren't enough tokens, the main script waits until it can launch more background threads that ping the next addresses on the list.
I was installing a game on my netbook with wine and it seems that it's using both of the cpu threads.
Did wine fix the multi-thread bug?
EDIT:
Sorry to get anyones hopes up, but I did later find that I was misreading some data. When I saw it say 100% cpu usage I thought it meant both threads, but I later found out that it only applied to one thread.
I have two threads & i want to run it continuously ,with while(1) it is possible . Is there any other way to run the threads continuously
View 12 Replies View RelatedIn all the examples I have found the server accepts the client's conection, proccess the data received and close the socket. In an very schematic way it would be something like:
Code:
client_thread{
select to see if there is data to read from socket fd
if there is something to read{
[code]....
Should I use mutexs or semaphores to block the socket fd before read and write or it is not necesary?

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.

I have 2 threads and both of them are deleting memory at the end nedded by both.
My problem is that maybe it can happen that a thread start and finish before the other one starts and so it deletes the memory nedded by the other thread. How can I synchronize them so that this can't happend.
As a design my threads look like this:
Code:
The other thread looks the same, but this isn't unoff to stop thread1 to finish before thread2 starts.
There is a transient bug in my code which I just can't catch.
The basic idea is this. I have a multithreaded server and two thread pools, the IO pool and Worker pool. The main server thread listens to incoming connections. When it gets one, it dispatches a thread from the IO pool to read the socket. An IO thread reads the socket. If there is data, it invokes a thread from the Worker pool. This thread then finishes off the processing including closing the socket. The code follows.
Before I show the code, let me tell you what's happening when I am testing it. I have a client program which has about 30 threads, each opening a separate socket connection with the server. Each sends a request which the server responds to. Sometimes I have all the threads finish in a zip. Sometimes both the client and the server hangs. And yet at other times, the client gets a connection refused message.
Now the code. I have omitted some of the nitty-gritties, including possibly variable declarations. I'll post them if it's required.
I have a multi-threaded application using pthreads. On application crash or when signalling with 'kill -s 6' the core file created by the 2.6.18-128 kernel on CentOS 5.3 shows only one single thread. Core file saved with gcore in gdb shows all running threads properly so the problem is clearly in the kernel. I tested CentOS 5.2 (kernel 2.6.28-92) and it works correctly.
what's wrong with CentOS 5.3 kernels?
Is there a quick way of saving the active threads of this forum, so that, I can read them later on without an internet connection?

I have a multithreaded program running. The threads are created by using pthread_create(). The ps shows a pid value for each thread in the process. The name of the thread is all the same as the parent process. I want to match the PID values in the ps output to the threads in my program. But when I used getpid() in each thread, the value I get is different from what ps shows. How do I match the pid value in ps output to the threads in my program.
