Hi Anuradha
This looks to be a problem with bugfix.8. A similar thing has occurred with
other parallel builds. Basically bugfix.8 added the -fast flag to the
loadline which was previously missing. This can improve performance but
-fast with the Intel compilers implies static linking and unfortunately a
lot of mpi installations do not include static versions of the libraries.
Hence why it says it cannot locate the library.
Try the following:
in $AMBERHOME/src/config.h change
PMEMD_FOPTFLAGS=-fast
to
PMEMD_FOPTFLAGS=-ipo -O3 -no-prec-div -xP
and try building again and now it should work fine.
Unfortunately the list of options changes with every version of the intel
compilers, hence why the use of -fast is so appealing. However, I think we
will need to release an update to bugfix.8 that removes the -fast from the
link stage and tries to be smarter in the options that are used.
All the best
Ross
