Parallel Distributed Systems Lab


The Parallel Distributed Systems Laboratory, established spring 2010, houses a 192 core cluster computers to support teaching and research in all areas of parallel and distributed computing: advanced computer architectures, operating systems, parallel programming languages, applications and high-performance computing and networking.

With the advances in the computer architecture field, all new computers, including laptops, are now multi-core systems. While the computer architectures have all moved to multi-core, the system software and programming of these computers have not advanced at the same rate of progress. In fact, AMD and Intel have announced that they will increase the number of cores on a chip in all future processors as have most computer companies.

For these computers to be used effectively, new system software, programming languages and applications must be designed with expertise in parallel and distributed systems. Industry is now looking for software designers with training in parallel and distributed systems for all of their new developments.

The multi-core cluster in the Parallel Distributed Systems Lab consists of 192 cores.

The cluster has 16 nodes. Each node has two CPUs with two sockets and six cores/socket (12 cores per node) with the following configuration:

Altus 1702 Server

  • 2 X Dual, AMD Opteron 2427, 2.2GHz, Six Core,
  • 6x512KB L2, 6MB L3 Cache
  • 2 x 24GB DDR2-667 ECC RAM (24 x 2GB)
  • 2 x 160GB, SATA, 7200RPM
  • 2 x AMD Opteron Dual Socket Motherboard with Integrated Infiniband DDR Connections

The host node also has 12 cores.

Altus 2701 Server

  • Dual, AMD Opteron 2427, 2.2GHz, Six Core, 6x512KB
  • L2, 6MB L3 Cache
  • 32GB DDR2-667MHz ECC RAM (8 x 4GB)
  • HW RAID 0/1/5/6/10/50: 3Gb/s 8-Port SAS Internal
  • RAID Adapter w/ 256MB Cache w/BBU
  • RAID 1 Volume: 238 GB (2+0 x 250GB SATA2)
  • RAID 5 Volume: 2861 GB (4+0 x 1TB SATA2)
  • HCA, Mellanox InfiniHost III Lx, PCIE, 1-port, DDR memfree

The computer users lab is located in North Classroom, room 2608. The machine is located in North Classroom, room 2612.
