Hi!
We're trying to compile HPCC on our OSCAR cluster and we can compile it
if we use mpich 1.2.7 but since we use LAM/MPI on our cluster we can't
run the benchmark. We get:
HPL ERROR from process # 0, on line 440 of function HPL_pdinfo:
>>> Need at least 4 processes for these tests <<<
As far as I've understud this is because we used mpich to compile HPCC
and uses LAM/MPI to run it. But if I change the makefile to use
lam-7.0.6 instead I get this compilation error:
/lam-7.0.6/lib/libmpich.a -lm
/opt/lam-7.0.6/lib/libmpi.a(lammpiinit.o)(.bss+0x0): multiple definition
of `MPIR_being_debugged'
/opt/lam-7.0.6/lib/libmpich.a(debugutil.o)(.bss+0x0): first defined here
collect2: ld returned 1 exit status
/opt/lam-7.0.6/bin/mpif77: No such file or directory
make[1]: *** [../../../../hpcc] Error 1

We've got the same problem when we uses just HPL. We can compile it with
mpich and then we can't run it and we can't compile it with lam-7.0.6.
At the moment are we using a precompiled blas_linux.a but we want to use
ATLAS instead. I've managed (I think) to compile ATLAS on our masternode
but that is a later project...
