[OMPI users] MPI_ERR_TRUNCATE on MPI_Testsome
I'm not sure how should I interpret this message: [local:17344] *** An error occurred in MPI_Testsome [local:17344] *** on communicator MPI COMMUNICATOR 5 CREATE FROM 0 [local:17344] *** MPI_ERR_TRUNCATE: message truncated [local:17344] *** MPI_ERRORS_ARE_FATAL (goodbye) mpiexec noticed that job rank 0 with PID 17338 on node local exited on signal 15 (Terminated). 3 additional processes aborted (not shown) I am assuming that the error was triggered because one of the buffers I set in the MPI_Recv_init() calls can not contain the incoming message. However, I don't understand why job rank 0 terminates first. The only process that contains a call to MPI_Testsome has actually rank 3, and it's receiving messages from rank 0. Also I think it would be a good idea to print the message tag in the error log.
Re: [OMPI users] which -lmpi is picked?
You can run "mpicc --showme" to see the exact underlying compiler/ linker command that is used (or, better yet, "mpicc foo.c -o foo -- showme"). This will include the -L path to where the Open MPI libraries are installed.

Re: [OMPI users] how to install openmpi with a specific gcc
http://www.open-mpi.org/faq/?category=building#build-compilers But this won't help build your app with the dusty, crumbling 2.95. You're telling OpenMPI (and all of OpenMPI, including mpicc) to use a specific compiler. You need to fix your code so it's portable.

Why do you need use this version ? the most part of moderns softwares recommends the use of gcc version 3 or greater (the best is version 4). -- Davi Vercillo Carneiro Garcia http://davivercillo.blogspot.com/ Universidade Federal do Rio de Janeiro Departamento de Ciência da Computação DCC-IM/UFRJ - http://www.dcc.ufrj.br Grupo de Usuários GNU/Linux da UFRJ (GUL-UFRJ) http://www.dcc.ufrj.br/~gul Linux User: #388711 http://counter.li.org/ "Theory is when you know something, but it doesn't work.

Hi! on my system the default gcc is 2.95.3. For openmpi i have installed gcc-3.4.6 but i kept the default gcc to stay gcc-2.95.3. Now, how can I configure/install openmpi with gcc-3.4.6?what options should i give when configuring it so that it doesnt go and pick upt the dafault 2.95.3 ???
