We have this IBM POWER5 machine with Linux SLES. The FFTW and GROMACS
are compiling without any errors (compiler is gcc), but when we are
trying to run a job on the machine, its exiting saying "illegal
instruction". Looking at the things, it seemed that the cpp it generated
is just a dummy, and cannot execute. I even tried using as
make CFLAGS='-mcpu=power5 -mtune=power5' for fftw and gromacs also, but
it doesnt seems to work.
If anyone can please help me out to osrt this problem..
Thanks in advance
