I am using mpirun with gcc-3.4.6 and mpicc-9.0 on an old parallel linux server, on which I don't have root rights. On using mpirun with 1 processors, I don't get error, however, on using 2 processors, I get

signal 11 received, exiting...

etc. errors.

I saw this SO post and was wondering if my system configuration may be such that new is not thread-safe. When I put printouts, I find that program gets stuck at call to new and does not even print what is expected. Can you suggest something. Thanks in advance.

Without root, I can install latest gcc in home directory, if that helps. Please let me know. Also do I need to install latest mpicc?

On other machines with gcc > 4.1, my program runs fine, but there I cannot run mpi.

Can you post a minimal example that produces the error? – suszterpatt Apr 11 '12 at 01:36
my code is spread over multiple files, so can you please comment on gcc version. – user984260 Apr 11 '12 at 02:49

signal 11 error is received, means segmentation fault error. – peaceman Apr 11 '12 at 04:47
