Can you use other compilers for Open MPI?
Open MPI seems to default to compiling with the GNU compiler set. Can I use other compilers? Can I pass specific flags to the compilers/linkers used to build Open MPI? I’m trying to compile with the Intel compilers, but Open MPI eventually fails to compile with really long error messages. What should I do?

How to fix MPI error loading shared libraries?
Rename the file to ‘libmpi.so.0’ After that the MPI jobs should run without any problem. If ‘libmpi.so’ is not found in ‘/usr/lib’, you can get its location with the following command. seems to me a better way to solve the problem (taken from a comment on this question).
Why is my MPI file not found?
The “file not found” error usually masks the true underlying cause of the problem. For example: note that Open MPI put a libltdl solution as of version 1.5. This solution should show the real reason why the plugin could not be loaded instead of the erroneous “file not found” message.
What happens when an MPI plugin does not load?

Where can I download OpenMPI from the source code?
A short guide on installing OpenMPI from source code. Download the Open MPI version with the .tar.gz suffix from the Open MPI download page. As far as the guide is concerned, the current stable version is openmpi-1.10.2.tar.gz.
How to run Open MPI without Slurm support?

Is there any solution to build Open MPI?
When building with the Oracle Solaris Studio 12 Update 1 (Sun) compilers on x86 Linux, the compiler loops in btl_sm.c. There is a solution? How do I build OpenMPI on IBM QS22 cell blade machines with GCC and XLC/XLF compilers? I am trying to compile with PathScale 3.0 and 3.1 compilers on Linux, but all Open MPI commands fail.
