I am trying to run the static_tov simulation on my university's cluster (CRC Notre Dame). However, I got this error when acquiring 48 cores:

I am assuming this is due to the #Source tree management module in the Cactus/simfactory/mdb/machines/<host>.ini file. In my case, the automatic *.ini file I got has these configuration:

ppn             = 24

max-num-threads = 24

num-threads     = 12

nodes           = 1

However, the machine I use has 24 cores for each node, and the number of threads for each core is 1. That means if I run the simulation using 48 cores, I need 2 nodes.

Although I didn't get 2 hosts successfully(I got only 1), I am wondering if I have to edit the <host>.ini file after the command ./simfactory/bin/sim setup-silent by hand, for example: num-threads=1, nodes=2? Or is there any other correct way for getting more than 1 node? 

I would be appreciate it if you could give me some ideas on this problem.

Best regards,

Wei
