Head nodes

Connection to IPSL ESPRI Mesocenter is made by SSH on the clusters head nodes. Clusters head nodes are WorldWide Open via ssh but only with ED25519 or RSA (4096 bits) key types and without any password asked upon connection (whereas a password is asked when deciphering your private key).

Head nodes adresses by cluster :

  • IPSL-SU, spirit:
    • spirit1.ipsl.fr 134.157.176.253 (24 cores, 256GB, EPYC 7402P 24-Core Processor 2.8GHz)
    • spirit2.ipsl.fr 134.157.176.129 (24 cores, 256GB, EPYC 7402P 24-Core Processor 2.8GHz)
  • IPSL-X, spiritx:
    • spiritx1.ipsl.fr 129.104.53.5 (24 cores, 256GB, EPYC 7402P 24-Core Processor 2.8GHz)
    • spiritx2.ipsl.fr 129.104.53.15 (24 cores, 256GB, EPYC 7402P 24-Core Processor 2.8GHz)
  • IPSL-G, hal: (GPU small cluster)
    • hal.ipsl.fr 194.254.41.69 (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.
