I've installed Scyld on a small cluster and I'm trying to
run the test programs that come with beompi
The codes run on one node. However, when I try to run
on multiple nodes I get the following error
jarrett/home/edwardsa>mpirun -np 2 pi3p
p0_28682: p4_error: net_create_slave: bproc_rfork: -1
p4_error: latest msg from perror: Invalid argument
jarrett/home/edwardsa>bm_list_28683: p4_error: interrupt SIGINT: 2
I have asked about this in a previous message, so here
are two more specific questions.
The master node has a hostname that is not node0. The first
slave node is, as far as beosetup, is node0. Is this a problem?
When beompi assigns nodes does it look at a machines file?
Should I install a HOSTNAME file on each slave?
