Yes, I do.

Someone from the LAM developing team has adviced me to define the
follow environment variable:
LAMHCC=mycompiler

I've tried it inside the mpicc script but I just can get this result:
PGF90-W-0093-Type conversion of expression performed (pcluster.f: 121)
  0 inform,   1 warnings,   0 severes, 0 fatal for MAIN
Linking:
pcluster.o: In function `MAIN_':
pcluster.o(.text+0x61): undefined reference to `mpi_init_'
pcluster.o(.text+0x80): undefined reference to `mpi_comm_size_'
pcluster.o(.text+0x9f): undefined reference to `mpi_comm_rank_'
pcluster.o(.text+0x9f2): undefined reference to `mpi_recv_'
pcluster.o(.text+0xa46): undefined reference to `mpi_send_'

pcluster.o(.text+0xd09): undefined reference to `mpi_finalize_'
pcluster.o(.text+0x1083): undefined reference to `mpi_finalize_'
hf77: Conseguido

So I supose it forgets the 'lmpi' parameter.
Can I discard the hcc script and execute my compiler directly into
mpicc??

Thanks,
Jaume,

PD: Si, tienes razon! ;)
