Subject: [OMPI users] unable to access or execute
From: Dominik Táborský (bremby_at_[hidden])

Hi again,

Since last time I made progress - I compiled openMPI 1.3.3 from sources,
now I'm trying to run it on one of my nodes. I am using the same
software on the master, but master is Ubuntu 9.04 (NOT using openMPI
1.3.2 from repos) and the node is my own Linux system - it lacks many
features so there might be the source of the problem.

When I try to run hello world program, it gives me this error:

$ /openMPI/bin/mpirun
-hostfile /home/eddy/Dreddux/host.machine5 ./projekty/openMPI/hello/hello
--------------------------------------------------------------------------
mpirun was unable to launch the specified application as it could not
access
or execute an executable:

Executable: ./projekty/openMPI/hello/hello
Node: machine5

while attempting to start process rank 0.
--------------------------------------------------------------------------

The executable is hello world program and is executable. I assume this
executable doesn't have to be on the node - that would be silly. So, I
don't understand what am I missing. Any ideas? Please!

Dominik

PS: thanks for your time!
