Here is list of issues that we figure out during ourMTT usage:
1. Installation of multiple MPIs failed.
MTT successfully installed the first mpi installation but the all other installations were installed under ~user directory. For solution please see mttlib.patch
2. Build of MPIs other than Open-mpi failed.
PrepareForInstall function in MTT/MPI/Get/Download.pm client was stay in install/src dir and not in install/src/<mpi vesion>.
please see mttlib_download.patch
