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.
------------------------------------------------------------------------
[ywan@frontend01 hello]$ mpif90 -fast -o hello -i-dynamic hello.f90
IPO: performing single-file optimizations
IPO: generating object file
/tmp/ipo_ifortTdJGQr.o
ld: cannot find -lmpi_f90
------------------------------------------------------------------------
The above command can be expanded as:
------------------------------------------------------------------------
[ywan@frontend01 hello]$ mpif90 -fast -o hello -i-dynamic hello.f90 -show
ifort -I/usr/local/Cluster-Apps/openmpi/intel/64/1.2.2//include -pthread
-I/usr/local/Cluster-Apps/openmpi/intel/64/1.2.2//lib -fast -o hello
-i-dynamic hello.f90 -L/usr/local/Cluster-Apps/openmpi/intel/64/1.2.2//lib
-lmpi_f90 -lmpi_f77 -lmpi -lopen-rte -lopen-pal -ldl -Wl,--export-dynamic
-lirc -lstdc++ -lnsl -lutil
-------------------------------------------------------------------------
mpif90 can find -lmpi_f90 if I remove -fast from above command.
Anyone knows the reseaon why OpenMPI not works with Intel -fast?
