[maker-devel] Maker MPICH2 issue (Multiple MAKER processes have been started in the same directory)

[Marc P. Hoeppner]

Dear list,

I know that MPICH2 related issues have been discussed previously, but 
the suggested solutions don't seem to work for me.
Briefly, I have set up a new cluster, with a fresh install of mpich2 (SL 
6.4, from the yum repos) and a newly compiled build of Maker 2.28.

When I start maker with mpiexec, I get spammed with
'WARNING: Multiple MAKER processes have been started in the same 
directory.'

Here is what I have tried so far - still getting the error :-< Any 
suggestions would be appreciated

--------
MPICH2
---------

which mpiexec:
/usr/lib64/mpich2/bin/mpiexec

Started the mpd ring as normal user across 5 nodes (bnode-01 to 
bnode-04, and the head node bhead)

mpdtrace:
bhead
bnode-02
bnode-03
bnode-04
bnode-01

mpdringtest:
time for 1 loops = 0.00128293037415 seconds

mpixec -n 32 -machinefile hostfile hostname:

<long list of host names, as ecpected>

I also ran the Skampi Mpi Benchmark, which ran through just fine.

MAKER

./Build status

PERL Dependencies:      VERIFIED
External Programs:      VERIFIED
External C Libraries:   VERIFIED
MPI SUPPORT:            ENABLED
MWAS Web Interface:     DISABLED
MAKER PACKAGE:          CONFIGURATION OK

During configuration/installation, Build.PL automatically detected all 
MPI data and never complained, so I have to assume that everything went 
fine there.
