Hello all,

I am kind of new to cluster operation, but have built 4 small sized (16 ­ 48
nodes) for other researchers.
Now, I¹m trying to run HPL on our 48-node dual Opteron 246 cluster.  Got it
to build 
the xhpl file, but when I try a test run I get the following error:

a48:/local-io/linux_bench/hpl/bin/Linux_Op_246 # mpirun -np 4 xhpl
/local-io/linux_bench/hpl/bin/Linux_Op_246/xhpl: Command not found.
p0_4305:  p4_error: Child process exited while making connection to remote
process on ath64: 0
p0_4305: (46.070312) net_send: could not write to fd=4, errno = 32

ath64 is a workstation I am not using for this task.

Any and all help on this matter would be greatly appreciated.
