Head nodes

Connection to IPSL ESPRI Mesocenter is made by SSH via the clusters head nodes.
Clusters head nodes are WorldWide Open via ssh but only with RSA key ( no password ).

Head nodes adresses by cluster :

  • IPSL-SU, ciclad:
    • ciclad.ipsl.upmc.fr 134.157.176.129 (32 cores, 128GB, AMD Opteron 6220 3Ghz)
    • ciclad2.ipsl.upmc.fr 134.157.176.252 (16 cores, 64Gb, Intel Xeon E5-2630v3 2.40GHz)
  • IPSL-X, climserv:
    • camelot.ipsl.polytechnique.fr 129.104.53.15 (16 cores, 64Gb, AMD Opteron 4274 HE 2.5GHz )
    • loholt1.ipsl.polytechnique.fr 129.104.53.12 (16 cores, 64Gb, Intel Xeon E5-2630v3 2.40GHz)
    • loholt2.ipsl.polytechnique.fr 129.104.53.14 (16 cores, 64Gb, Intel Xeon E5-2630v3 2.40GHz)
  • IPSL-G, hal: (GPU small cluster)
    • hal0.obs.uvsq.fr 194.254.41.50 (VM, just access and file transfert, no scientific software on)

To connect to a specific cluster head node, you simply execute the command ssh your_mesocenter_login@head_node_name

Your mesocenter login grants your access to all IPSL ESPRI clusters.

The head nodes are set to run short and low memory interactive jobs and may be refer also as interactive nodes page. Futher information about thoses nodes are in the dedicated page.
