Hi,
I have compiled version 7.0.6 of lam-mpi on RH linux.
I had to use different vendors for C and fortran compilers: I used cc and c++, and pgf90. I know that it is preferible not to do so, but my fortran programs are in pgf90 and I do not have the C compilers from PGI.
The examples that come with the distribution run OK. I run hello, pi and trivial.
The result of 'mpif77 -showme' is
pgf90 -I/home/mrb/bin/lam7_bin/include -L/home/mrb/bin/lam7_bin/lib -llammpio -llamf77mpi -lmpi -llam -lutil -lpthread
and of 'laminfo' is
LAM/MPI: 7.0.6

When I run my program (in pgf90) I get the following error, and the program stops:
0: init_descriptor: invalid target descriptor
-----------------------------------------------------------------------------
It seems that [at least] one of the processes that was started with
mpirun did not invoke MPI_INIT before quitting (it is possible that
more than one process did not invoke MPI_INIT -- mpirun was only
notified of the first one, which was on node n0).
mpirun can *only* be used with MPI programs (i.e., programs that
invoke MPI_INIT and MPI_FINALIZE). You can use the "lamexec" program
to run non-MPI programs over the lambooted nodes.
-----------------------------------------------------------------------------
I have seen in the mailing list that many other people have had the same error message, but it is not clear to me what the cause can be.
There was no lam installed in the machine before I installed version 7.0.6.
I really appreciate your help. Thank you!
