Hey Balaji I'm new at it too, but might be able to help you a bit.
A sigsegv error occurs usually when you try to access something in memory that's not actually there. Like using a pointer that points to nothing. In my short experience with MPI so far, I got this kind of message when I made something wrong with the functions, like for example sending a buffer and, when telling MPI it's size, giving a wrong value. Make sure there's nothing like that on your code. For the time thing, I think that what you want is the MPI_WTime() function. Check this out: https://computing.llnl.gov/tutorials/mpi/man/MPI_Wtime.txt Best, Giovani balaji srinivas <balajisriniva...@rediffmail.com> escreveu: hi all, I am new to MPI. The outline of my code is if(r==0) function1() else if(r==1) function2() where r is the rank and functions are included in the .h files. There are no compilation errors. I get the SIGSEGV error while running. Pls help. how to solve this? 2) how to find the execution time of a mpi program. in C we have clock_t start=clock() at the beginning and ((double)clock() - start) / CLOCKS_PER_SEC) at the end. Thanks in advance. regards, balaji. _______________________________________________ users mailing list us...@open-mpi.org http://www.open-mpi.org/mailman/listinfo.cgi/users --------------------------------- Abra sua conta no Yahoo!
