Problems with MPICH 1.2 and Beowulf/Linux

[Francesco Marini]

Hi all,

    I've got a really weird problem with MPICH 1.2.
    The system consists of a server and 16 computing nodes, all
diskless, mounting root via NFS from the server.  It works very well
with pvm and LAM-MPI.
    Now, I'm trying to compile the latest source of MPICH, the make
process goes well, but when I try to "make testing" I get this output
(repeated for all tests using more than 1 machine) :

    Seems like MPICH cannot start the remote process or cannot establish
the connection. The crazy thing is that with pvm and LAM-MPI all goes
well.

    Any idea ?

    Second : I've got some prob compiling ScaLapack with LAM-MPI, gcc
and pgf77 (f77 compiler from Portland Group), it gives a lot of
unresolved symbols regarding MPI. Anyone succeded in compiling them
under same configuration ?

    Thank you all in advance,
