Actually, that's not true - the 1.5 series technically still supports
assignment to physical cpus. However, it is never really tested and very
unusual for someone to use, so I suspect it is broken. I very much doubt anyone
will fix it.
Also, be aware that physical cpu assignments are not suppor
I made a mistake in the previous reply. You can use two ways here like:
rank 0=host1 slot=0
rank 1=host1 slot=2
rank 2=host1 slot=4
rank 3=host1 slot=6
rank 4=host1 slot=1
rank 5=host1 slot=3
rank 6=host1 slot=5
rank 7=host1 slot=7
or
rank 0=host1 slot=0:0
rank 1=host1 slot=0:1
rank 2=host1 slot=
Just remove p in your rankfile like
rank 0=host1 slot=0:0
rank 1=host1 slot=0:2
rank 2=host1 slot=0:4
rank 3=host1 slot=0:6
rank 4=host1 slot=1:1
rank 5=host1 slot=1:3
rank 6=host1 slot=1:5
rank 7=host1 slot=1:7

Hello,
I need to use a rankfile with openMPI 1.5.4 to do some tests on a basic
architecture. I'm using a node for which lstopo returns that :
Machine (24GB)
NUMANode L#0 (P#0 12GB)
Socket L#0 + L3 L#0 (8192KB)
L2 L#0 (256KB) + L1 L#0 (32KB) + Core L#0 + PU L#0 (P#0
