Hi,
   I am using Oscar 4.2. I have two ethernet cards on compute nodes,
eth0, eth1[one 10/100Mbps and one realtek 8169 gigabit NIC] and 4
ethernet cards on the head node , eth0 10/100Mbps, eth1 10/100Mbps, eth2
realtek 8169 gigabit, eth3 a built in 3com gigabit ethernet with the
sk98lin driver. I am using FC3. Can you give me an mpirun command for
this hardware to run hpl?
The command line i use looks like:
mpirun --mca btl_tcp_if_include eth2 --mca btl tcp --hostfile aa -np 16
./xhpl from the benchmark directory.
But it spews out with errors about eth2 and not being able to find the
HPL.dat file.
All the 8169 cards on all nodes are connected by Gig copper cables to a
16 port gigabit switch .
Thank you very much,
Allan
