Cluster Specs


VACC hardwareUVM's Enterprise Technology Services (ETS) has completed the third major upgrade to the high performance computing (HPC) cluster.

More than doubling the total number of computing cores available to faculty and student users, the upgrade also showcases a continued investment at UVM in "green computing," with next generation IBM hardware chosen for the upgrade bringing up to 30% more energy efficiency than equivalent HPC systems.

Multi-year grants from NASA, championed by US Senator Patrick Leahy, give strong support to the VACC.

The IBM Bluemoon cluster has a total compute node count: 380. total x86_64 compute core count: 3144.

As of September 2013, the Bluemoon cluster consists of:
