[mpich-discuss] Node vs CPU control

[Robertson, Andrew]

Folks,

I have a 16 node cluster with 4 cpus per node. I would like to just
leave an mpd up and running that was booted on all 16 nodes with four
cpus per node. 

Ie 

NodeName:4 

On each line of my hosts file

 

Is there a way to force jobs which use less than the full cluster to
spread out and use an equal number of CPUs on each node? I find that  if
for instance I ask for 16 cpus I get four nodes with four cpus each, I
would like to get 16 nodes with on cpu each? 

 

Still getting the hang of all this

Any help is appreciated

 

Thanks

 

 

-Andy
