Hello,
I have just installed Open MPI 1.1 on a 64-bit FC6 machine using yum.
The packages that were installed are:
openmpi-devel-1.1-7.fc6
openmpi-libs-1.1-7.fc6
openmpi-1.1-7.fc6
I tried running ompi_info, but it results in a segmentation fault.
Running strace shows this at the end:
mmap(NULL, 4294967296, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS,
-1, 0) = -1 ENOMEM (Cannot allocate memory)
--- SIGSEGV (Segmentation fault) @ 0 (0) ---
+++ killed by SIGSEGV +++
The full output of ompi_info is:
# ompi_info

Segmentation fault
It seems that at this point in the program, it tries to map 4GB of
memory, which results in ENOMEM. I'm guessing that the return value of
mmap isn't checked, which results in this segmentation fault.
Also, I tried running "mpirun", and the output was:
# mpirun
*** buffer overflow detected ***: mpirun terminated

It also included a "Memory map", which I left out.
Any suggestions?
Thanks in advance,
