Title: ATK Sabalcore no of nodes
Post by: ams_nanolab on February 17, 2017, 18:45

Dear Sir,

What is the maximum available number of nodes and cores per node for running ATK on demand on Sabalcore?

I saw the tutorial
http://docs.quantumwise.com/guides/atk_on_demand/atk_on_demand_sabalcore.html

where it's said:

You can see the list of available nodes and corresponding details by logging ini via SSH to Sabalcore and use the command upnodes

but how to login to sbalcore via ssh ?

To log in you must have an account. I'm not sure I am permitted to give an exact core count here, but  there are 4 clusters in total, and 2 of these have over 320 cores each. There is a smaller one with 24 and the middle one has over 150 cores. However, it's unlikely that you can reserve more than 256 cores for a job, I would say, due to other jobs running. But 64 shouldn't be a big problem, maybe also 128 if you are ok to wait in the queue a bit.
