QUEST2 Nodes

• • Number of nodes: 21

  • CPU model name: Hexacore Intel Westmere Xeon processors

  • CPU MHz: 2660

  • Number of cores per node: 12

  • Memory : 48GB

Linux Clusters

Wolverton research group has four linux clusters from Microway and all except one are located at Tech LG87, with the exception at 2020 Ridge. Total number of CPU cores is 1008.

Administrators of the clusters are Logan, Tony and Scott. The access to guerrero is limited to on-campus, so that one needs to use VPN to get connected from off-campus. Upon request, an ip-address of group member can be added to the /etc/hosts.

SMP Machines

Wolverton research group also has three small SMP machines for classes and simple calculations. Two are currently located at Bodeen. Morales is being shared with Dr. Kathleen Stair for her undergraduate labs, so please try to minimize use of morales during the class. Larue is primarily devoted to hosting our high-throughput DFT database, the OQMD, and is located in the students office, Tech EG27.
