[mpich-discuss] MPICH2 problem

[Grzegorz Dwornicki]

Hello

If im writing double message on list pls let me know.

Im writing a graduating paper on my university about MPICH and im having
some trouble launching programs. For example I need to run perfomance tests
on cluster, to determine it max. potencial. To do this Im using hpl linpack
from http://www.netlib.org/benchmark/hpl/. Compilation goes without any
errors but when I type f.e:

mpirun -np 4 ./xhpl

Im getting output like this:
0 - <NO ERROR MESSAGE> : Could not convert index 1140850688 into a pointer
The index may be an incorrect argument.
Possible sources of this problem are a missing "include 'mpif.h'",
a misspelled MPI object (e.g., MPI_COM_WORLD instead of MPI_COMM_WORLD)
or a misspelled user variable for an MPI object (e.g.,
com instead of comm).

Ive found on the Web information that this is fault of using mpich1 not
mpich2, soo Ive upgrades mpich to mpich2:

 dpkg -l | grep mpich
(...)
ii  libmpich2-1.2                        1.2.1.1-4                    Shared
libraries for MPICH2
ii  mpich-bin                            1.2.7-8                      MPI
parallel computing system implementation
ii  mpich2                               1.2.1.1-4
Implementation of the MPI Message Passing In
(...)

And this doesn't help. I admit that Im stuck, on internet I cant find
anythig usefull.

p.s. mpd apears to work.

sry for my bad english
Gregory
