Cluster "Survey"
 
Hello:

Just wondering if we could do a quick survey for those who work in industry and utilize a cluster...

Specifically I am curious:

1) Generally, how big is your company (i.e. hundreds, thousands, tens of thousands)
2) How much access do you have to your cluster (direct to hardware, remote desktop, terminal, web-based, etc.)
3) How big is your cluster core wise (in general terms..i.e. ~30 cores, ~100 cores, etc)
4) How many cells is your typical problem & maximum size problem?

...and anything else you think might be relevant.

1 - > 100
2 - direct access (terminal, web and remote desktop also) for department cluster and terminal access to institute cluster
3 - 80 cores department cluster and 400 cores institute cluster
4 - 2-10M typical mesh size, 50M Max mesh size

1 - University, number of users of cluster < 10.
2 - SSH Terminal / SFTP. No X11 (waste of processor power!), therefore no desktop
3 - 2 x 100 core + 2 x 200 core clusters
4 - Research projects, so vary. 25M LES up to 120M RANS

1) 20 (cluster users:1)
2) Direct
3) 24

Just like in the locker room, I have the smallest one!

1) 1 employee
2) Direct
3) 12 real cores on 2 nodes (HT off) - 64 GB RAM
4) 1-10M

...
I was talking about my small corner locker, Jeez what were you guys thinking!

1) ~550 employees, ~50 in our office, ~25 cluster users
2) SSH / display forwarding
3) 1x 1024 cores, 1x 256 cores. Similar equipment in other offices.
4) 500K to 120M, but there are too many different applications to say what's typical

1) 4 employees, 2 users
2) SSH
3) 256 cores out of a cluster with 1024 cores
4) 1M to 35M, typically 4-6M. marine applications

1) ~1300 employees, ~5 in our office, ~2 cluster users
2) direct to hardware if necessary, remote desktop, terminal
3) 192 cores, 16 nodes Dell cluster
4) 1-7M typical mesh size, 15M max mesh size
