[gmx-users] Problems running in paralell on IBM SP

[David L. Bostick]

Hi Erik,

If I don't give CFLAGS or FFLAGS when I run configure, I get for the system
detected,
.
.
./configure --enable-mpi --prefix=/gpfs/dbostick/gmx-3.1
--disable-largefile --program-suffix="_mpi"
checking build system type... powerpc-ibm-aix4.3.3.0
checking host system type... powerpc-ibm-aix4.3.3.0
checking for a BSD compatible install... config/install-sh -c
checking whether build environment is sane... yes
.
.
and for the flags 
.
.
checking how to run the C preprocessor... mpcc -E
checking whether mpcc accepts -O3 -qmaxmem=16384... ./configure[5048]: ==:
unknown test operator
no
