Hello all,
I am kind of new to cluster operation, but have built 4 small sized (16
– 48 nodes) for other researchers.
Now, I’m 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
Is the /local-io filesystem shared amongst all nodes, or is it the
local disk? The executable needs to be on a shared filesystem where
all applications can see it.
This is probably why you got the "command not found' error.

ath64 is a workstation I am not using for this task.
Any and all help on this matter would be greatly appreciated.
Thanks,
