Interactive Nodes


For CentOS 7.2 access, "ssh ifarm.jlab.org" to reach the interactive nodes ifarm1401 and ifarm1402.jlab.org:

  • ifarm1402: dual 12 core 2.5 GHz Xeon (Haswell), hyperthreaded, 64 GB memory, dual 1 TB striped disks, /scratch, QDR IB
  • ifarm1401: dual 12 core 2.5 GHz Xeon (Haswell), hyperthreaded, 64 GB memory, dual 1 TB striped disks, /scratch, QDR IB

For the CentOS 6.5 systems, use the "ifarm65.jlab.org" alias to access the interactive node. 

  • ifarm1101: 32-core AMD Opteron, 64GB RAM, 1TB local /scratch

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.
