Remote SSH to Dataplex from FEP

Details

Access to gpu.grid.pub.ro will be done through our frontend (fep.grid.pub.ro). A new queue was created (ibm-dp.q) in which all the Dataplex machines were added (dp-wn01:dp-wn04).

Console access was preserved and is done through "qlogin" program:

[mihai.carabas@fep-62-1 ~]$ qlogin -q ibm-dp.q

X11 forwarding is also active.

You can reserve multiple queue slots (up to 24 for a machine) using "-pe" option. If you reserve 24 slots, you are sure that nobody can login to that machine:

[mihai.carabas@fep-62-1 ~]$ qlogin -q ibm-dp.q@dp-wn03 -pe openmpi 24
