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".

scconf_transp_adap_bge(1M) System Administration Commands scconf_transp_adap_bge(1M)
NAME
scconf_transp_adap_bge - configure the bge transport adapter
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.
You can configure bge adapters as cluster transport adapters. These adapters can only be used with the dlpi transport type. The bge adapter
is VLAN capable.
The bge adapter connects to a transport switch or to another bge adapter on a different node. In either case, the connection is made
through a transport cable.
When a transport switch is used and the endpoints of the transport cable are configured by using the scconf command, the scinstall command,
or other tools, you are asked to specify a port name on the transport switch. You can provide any port name, or accept the default, as long
as the name is unique for the switch.
The default is to set the port name to the node ID hosting the adapter at the other end of the cable.
There are no user configurable properties for cluster transport adapters of this type.
