Cluster 8

We are still learning about FAC/coreHPC.

you will need to get separate (?) FAC and coreHPC accounts.

• FAC is for storage
• coreHPC is for compute
• it is more complicated than that, but it is a reasonable simplification.

• We collectively refer to FAC/coreHPC as "Cluster 8".
• We are attempting two strategies for cluster 8:
  • upload ZINC on the fly, dock it, and then throw it away.
  • nfs mount our cluster on coreHPC, data gets pulled as needed

• ZINC thus lives on our cluster (currently hosted on cluster 2, cross mounted read only to cluster 7).
• a copy of 50% of ZINC lives on Wynton/cluster 3.
• The pipe to FAC is 100 Gbps. Assming we get 50% of that, allows 1 TB in 3 minutes, and 3 PB is 6 days.
• thus, ftp/dock/delete.

• to get to corehpc

ssh <user>@chpc-ucsf-bastion-vm1.corehpc.ucsf.edu

• to get to slurm head node

ssh chpc-ucsf-login-vm1

• disks are

/mnt/scratch/user/<user>. 
/mnt/home/<user> 
/home/remote/<user>  ; you land here when you login

Anyone who uses coreHPC, please take notes, update this and other pages, and teach the rest of the lab how to use it. Thank you.
