[torqueusers] NUMA -- A first try

[Svancara, Randall]

Hi,

I have compiled torque 3.0.4 with NUMA support per this document.

http://www.clusterresources.com/torquedocs21/1.7torqueonnuma.shtml

I have created the server_priv/nodes and mom_priv/mom.layout file

Here are the versions of software:

[root at node11 bin]# pbs_mom -v
version: 3.0.4

[root at mgt1 server_priv]# pbs_server -v
version: 3.0.4

lstopo shows:

Mom.layout:

server_priv/nodes:
node11 num_numa_nodes=2 compute

I restart pbs_server on management node and pbs_mom on node11.
pbsnodes -a  shows

     np = 0
     properties = compute
     ntype = cluster

     gpus = 0

     ntype = cluster

     mom_manager_port = 15003
     gpus = 0


mom_log on node11 has:

My problem as illustrated from the pbsnodes command above is that node11 is down.  And running strace on the pbs_mom process does not indicate any access to the mom.layout file?

So did I really compile NUMA support?  I can see references to NUMA in the Makefile for torque and the config.log definitely has the right parameters:

  $ ./configure --prefix=/usr --with-blcr=/usr --enable-numa-support --disable-gui --enable-blcr --with-default-server=mgt1 --with-servchkptdir=/fastscratch/tmp --with-tmpdir=/fastscratch/tmp

Can anyone provide further illumination on my already dark dreary day?
