The HPCC community has been offered a SGI Altix 3000 (purchased in 2003?/2006?), basically a half rack on wheels (20U or so). The Altix has 4 IA-64 processors (family Itanium 2) which aren't particularly fast (1.3 Ghz), but The Altix has 96 GBytes of memory and so is useful for some large Gaussian jobs which aren't particularly suited to running on our current HPCC cluster design (More details to come on this issue).

It is running redhat AS2.1 (which definitely ages it), so basic Linux. The node has been configured to fit our environment and will provide

• /home from file server sharptail, over ethernet
• /sanscratch from scratch server greentail, over ethernet
• Openlava 2.2 stand alone installation
• icc/ifort version 8.1 on local disk
• Gaussian version ?.?? on local disk

In order to use the local compilers you must “source” the following files to override the default 2016 icc/ifort compilers in your path:

  .  /opt/intel_cc_80.8.1-028/bin/iccvars.sh
  .  /opt/intel_fc_80.8.1-024/bin/ifortvars.sh

You can also find MKL libraries at /opt/intel/mkl60.

All Openlava commands work the same way as elsewhere in our HPCC environment. In order to use the SGI Altix you must SSH to the head/compute node from any of our “tail” login nodes (ie cottontail, swallowtail)

In order to run Gaussian jobs you must be a member of the unix group gaussian and agree to accept /share/apps/gaussian/License.pdf.
