Hi everybody! Here is my problem : I wrote a c++ program on Linux which uses the pthread library to handle several requests of several clients. Each request executes an algo in which some parts, some loops, are parallelized with openmp (on 2 processors). I compile my program with gcc 4.3. With one request, so with one tread created by pthread lib, there is no problem, the execution is ok, and I have no problem with the openmp directives. But, when I execute my code with several requests, a deadlock, or a segmentation fault, occurs at execution, precisely when the second thread enters an openmp part. I have already searched for a solution on the web, and on this forum too, I found some answers saying that there is a problem with gcc 4.2 and 4.3 and openmp with multithreading, so I try with gcc 4.5 but it doesn't correct the problem. There is no error in my code, in the declarations of my variables, in the openmp directives,... and I really think it is due to gcc because the code works when I compile it with the intel c compiler.
I hope someone will have a solution :) . Thanks -- View this message in context: http://old.nabble.com/Problem-compiling-a-program-with-openmp-and-multithreading-tp29170883p29170883.html Sent from the gcc - bugs mailing list archive at Nabble.com.
