Pete

Overview of Pete

The Pete cluster is composed of two parts, one owned by Earth and Atmospheric Sciences (EAS) and the other by the Network for Computational Nanotechnology (NCN). Pete consists of 166 HP Dual-Processor Dual-Core DL 40 systems with either 8 or 16 GB RAM and Gigabit Ethernet. The large amount of memory in this system makes it well suited for large parallel jobs. With 4 cores per node, sizeable multithreaded programs (parallel codes that do not use MPI) would not be a good fit for Pete.

Detailed Hardware Specification

Pete is divided into two sub-clusters, one for EAS and one for NCN. The difference is mainly the amount of memory.

Sub-Cluster Number of Nodes Processor Cores per Node Memory per Node Interconnect TeraFlops
Pete-EAS 84 Dual 2.33 GHz Dual-Core
Intel Xeon E5140		 4 8 GB Gigabit Ethernet 3.13
Pete-NCN 82 Dual 2.33 GHz Dual-Core
Intel Xeon E5140		 4 16 GB Gigabit Ethernet 3.06

Pete also features a 17 TB NFS scratch filesystem and a 16 TB Lustre scratch filesystem.

All Pete nodes run Red Hat Enterprise Linux 4 (RHEL4) and use PBSPro 9.x for resource and job management. Operating system patches are applied monthly or as security needs dictate. All nodes have been configured to allow for unlimited stack usage, as well as unlimited core dump size (though disk space and server quotas may still be a limiting factor).
