Re: [OMPI users] redirecting output

2012-03-30 Thread François Tessier 

Hello!

Did you try to redirect also the error output?Maybe your application 
write its output on stderr.

[OMPI users] Using physical numbering in a rankfile

2012-02-02 Thread François Tessier 

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)
  L2 L#1 (256KB) + L1 L#1 (32KB) + Core L#1 + PU L#1 (P#2)
  L2 L#2 (256KB) + L1 L#2 (32KB) + Core L#2 + PU L#2 (P#4)
  L2 L#3 (256KB) + L1 L#3 (32KB) + Core L#3 + PU L#3 (P#6)
HostBridge L#0
  PCIBridge
PCI 8086:10c9
  Net L#0 "eth0"
PCI 8086:10c9
  Net L#1 "eth1"
  PCIBridge
PCI 15b3:673c
  Net L#2 "ib0"
  Net L#3 "ib1"
  OpenFabrics L#4 "mlx4_0"
  PCIBridge
PCI 102b:0522
  PCI 8086:3a22
Block L#5 "sda"
Block L#6 "sdb"
Block L#7 "sdc"
Block L#8 "sdd"
  NUMANode L#1 (P#1 12GB) + Socket L#1 + L3 L#1 (8192KB)
L2 L#4 (256KB) + L1 L#4 (32KB) + Core L#4 + PU L#4 (P#1)
L2 L#5 (256KB) + L1 L#5 (32KB) + Core L#5 + PU L#5 (P#3)
L2 L#6 (256KB) + L1 L#6 (32KB) + Core L#6 + PU L#6 (P#5)
L2 L#7 (256KB) + L1 L#7 (32KB) + Core L#7 + PU L#7 (P#7)


And I would like to use the physical numbering. To do that, I created a 
rankfile like this :


rank 0=host1 slot=p0:0
rank 1=host1 slot=p0:2
rank 2=host1 slot=p0:4
rank 3=host1 slot=p0:6
rank 4=host1 slot=p1:1
rank 5=host1 slot=p1:3
rank 6=host1 slot=p1:5
rank 7=host1 slot=p1:7

But when I run my job with "/mpiexec -np 8 --rankfile rankfile ./foo/", 
I encounter this error :


/Specified slot list: p0:4
Error: Not found

This could mean that a non-existent processor was specified, or
that the specification had improper syntax./


Do you know what I did wrong?

Best regards,

François
