We have recently installed the Intel 10,1 compiler suite on our cluster.
I built OpenMPI (1.2.7 and 1.2.8) with
./configure CC=icc CXX=icpc F77=ifort FC=ifort
It configures, builds and installs.
However, the MPI compiler drivers (mpicc, mpif90, etc) fail immediately
with error of the sort
mpif90: error while loading shared libraries: libimf.so: cannot open
shared object file: No such file or directory
I updated the LD_LIBRARY_PATH to point to the directories that contain
the installed copies of libimf.so. (this is not something I have not had
to do for other compiler/OpenMpi combinations)
At that point, the program will compile but I get warnings like:
[muno@titan ~]$ mpif90 test.f
/share/apps/Intel/fce/10.1.018/lib/libimf.so: warning: warning:
feupdateenv is not implemented and will always fail
In a google search, I found a reference to this in the OpenMPI lists.
When I follow the link, it is a different thread. Searching the OpenMPI
lists from the web page does not find any matches. Strange.
I found some references to this at some other sites using OpenMPI on
clusters and they said to use
-i_dynamic
on the compile line.
This removes the warning.
Is there something I should be doing at OpenMPI configure time to take
care of these issues?
