Is multithreading possible in c on linux platform

[gnanapoongothai]

HI,
i am assigned a project of grid computing. so i must know where multithreading is possible on linux. ANd by how u can do that. I know in windows MPC is available. What about linux?

HI,
You can posix multithreading in C in Linux.
Try to do a search with "Posix multithreading" and u will get the info u need.

Thanks

Hi,
Thanks for ur advice. Is that both MPc and posixs are compatable.Mean s i want to develope an application which distribute threads to the other pcs .and it has to send the result. THe same applicaton is it possible in linux and windows.

Can you be more clear in ur requirement, what exactly you want to do??

Google for 'MPI' (Message Passing Interface); it does exactly what you want.

kind regards,

You cannot have the same threads run on both Linus and Windows. Threads on Linux must have the form:

[code=c]
void* MyThread(void*) ;
[/code]

On Windows the threads must have this form:
[code=c]
DWORD WINAPI MyThread(LPVOID );
[/code]

You will need Linus code and Windows code and then you must compile separately for each OS.

Or use the Windows port of MPI; it's a great product; I can recommend it; I've
used several computer architectures ranging from Windows PCs to 512 node
IBM PSs and a bunch of Crays, all in one virtual parallel machine cluster. MPIch
is a free implementation. Google for it; it's easily found; and it's fun to use.

kind regards,
