Interactive login machines


For CentOS 7.7 access, "ssh ifarm.jlab.org" to reach the interactive nodes ifarm1801, ifarm1802, and ifarm1901.jlab.org:

  • ifarm1801 and ifarm1802: dual 20 core 2.4 GHz Xeon (Skylake), hyperthreaded, 96 GB memory, /scratch, QDR IB
  • ifarm1902: dual 64 core AMD EPYC 7502, threaded, 256BG of memory, 1TB /scratch, FDR IB


You are free to use these nodes for software development and testing, but do not run long tasks interactively.


These interactive machines are not accessible from offsite; you will first need to "ssh login.jlab.org".  Similarly, the interactive nodes can't reach offsite nodes.
