i've run my mm5 weather modeling app over mpich gig-e & myrinet, & open-mpi gig-e. when i tried open-mpi over myrinet, i was able to compile & run w/o issue, but i get no net traffic over the myrinet switch. the job cranks up the cpu's but never completes. i'm using the myrinet MX driver. i have the myrinet libs set in both LD_LIBRARY_PATH & the ld.so.conf file. any advice/suggestions would be greatly appreciated. i've listed my compile options below:
MCC = $(LINUX_MPIHOME)/bin/mpicc MFC = $(LINUX_MPIHOME)/bin/mpif90 MLD = $(LINUX_MPIHOME)/bin/mpif90 FCFLAGS = -xP -O3 -DDEC_ALPHA -convert big_endian -I/raid1/pchilds/mm5/include -I/raid1/pchilds/mm5/MM5/include -I$(LINUX_MPIHOME)/include LDOPTIONS = -tpp7 -axP -pc32 -convert big_endian CPPFLAGS = -DDEC_ALPHA -traditional -DMPI -Dlinux CFLAGS = -DDEC_ALPHA -DMPI -I$(LINUX_MPIHOME)/include -DSGI_IA64 ____________________________________________________________________________________ Yahoo!
