That is trying to run it on 8 cores across 2 nodes. I have also tried your HPL.dat you provided, and i get a similar error except it says Need at least 12 processes.
Do you know what causes these errors. I have a hosts file in the same directory with the names of the two nodes which i wish to run the tests on.
At the command line i am typing:
mpirun -np 8 -machinefile hosts xhpl_em64t
where hosts file has the names:
machine1
machine2
Several points:
- The number of processor-cores you run this thing on must match the product of P and Q. So if P is 2 and Q is 4, you will need 8 cores; no more, no less
- If you provide MPICH with -np 8 and you specify a machine file, it expects at least that number of hosts in the machine file. If a host has multiple processor-cores (in your case, yes of course), you enter the hostname for each core. So if machine1 has 8 processor cores, your machinefile should include 8 lines of "machine1".

scsetup
scsetup(1M) System Administration Commands scsetup(1M)
NAME
scsetup - interactive cluster configuration tool
SYNOPSIS
scsetup [-f logfile]
DESCRIPTION
Note -
Beginning with the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software
still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more infor-
mation about the object-oriented command set, see the Intro(1CL) man page.
The scsetup command provides the following configuration capabilities, depending on what state the cluster is in when you issue the com-
mand:
o When you run the scsetup command at post-installation time, the command performs initial setup tasks, such as configuring quorum
devices and resetting the installmode property. If you did not use automatic quorum configuration when you created the cluster,
run the scsetup command immediately after the cluster is installed. Ensure that all nodes have joined the cluster before you run
the scsetup command and reset the installmode property.
If you used automatic quorum configuration when you created the cluster, you do not need to run the scsetup command after clus-
ter installation. The automatic quorum configuration feature also resets the installmode property of the cluster.
o When you run the command during normal cluster operation, the scsetup command provides a menu-driven utility. You can use this
utility to perform most ongoing cluster-administration tasks.
o When you issue the command from a node that is in noncluster mode, the scsetup utility provides a menu-driven utility for chang-
ing and displaying the private IP address range. You must reboot all nodes into noncluster mode before you start this form of
the scsetup utility.
You can issue the scsetup command from any node in the cluster.
You can use this command only in the global zone.
OPTIONS
The following options are supported:
-f logfile Specifies the name of a log file to which commands can be logged. If you specify this option, most command sets that
the scsetup utility generates are run and logged, or only logged, depending on user responses.
