This looks like a compiler issue, to me. It is probably worth asking
your Intel compiler support people as to why this happens.
I tried with both icc 9.1 and 10.0 and am able to replicate your
findings:
it works fine without -fast, but claims that it can't find mpi_f90
when you use -fast:
shell% ifort -I/home/jsquyres/bogus/include -pthread -I/home/jsquyres/
bogus/lib hello.f90 -o hello -L/home/jsquyres/bogus/lib -lmpi_f90 -
lmpi_f77 -lmpi -lopen-rte -lopen-pal -ldl -Wl,--export-dynamic -lnsl -
lutil
/opt/intel/9.1/lib/libimf.so: warning: warning: feupdateenv is not
implemented and will always fail
shell%
And (icc 9.1):
shell% ifort -I/home/jsquyres/bogus/include -pthread -I/home/jsquyres/
bogus/lib hello.f90 -o hello -fast -L/home/jsquyres/bogus/lib -
lmpi_f90 -lmpi_f77 -lmpi -lopen-rte -lopen-pal -ldl -Wl,--export-
dynamic -lnsl -lutil
IPO: performing single-file optimizations
IPO: generating object file /tmp/ipo_ifort93yZWY.o
ld: cannot find -lmpi_f90
shell%
With icc 10.0:
shell% mpif90 hello.f90 -o hello -fast
ipo: remark #11001: performing single-file optimizations
ipo: remark #11005: generating object file /tmp/ipo_ifortAT0da4.o
ld: cannot find -lmpi_f90
shell%

Hi all,
I'm using OpenMPI 1.2.2 with Intel compilers (icc, ifort)
But I found mpicc and mpif90 cannot work with Intel -fast
optimisation.

The above command can be expanded as:

[ywan@frontend01 hello]$ mpif90 -fast -o hello -i-dynamic hello.f90

mpif90 can find -lmpi_f90 if I remove -fast from above command.
Anyone knows the reseaon why OpenMPI not works with Intel -fast?
