Dear All,
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.
cpp is not generated by the above process. It needs to be already
present on your machine.
You'd also be well advised to tell us *which* gromacs program you're
trying to run when you get your "illegal instruction", because we can't
read minds.
I even tried using as
make CFLAGS='-mcpu=power5 -mtune=power5' for fftw and gromacs also, but
it doesnt seems to work.
