The Accelerator Research Cluster (ARC) is a technology evaluation cluster with a combination of 14 IBM PowerXCell 8i "Cell" nodes and 8 Intel x86_64 "Nehalem" nodes containing NVIDIA GPUs. The QS22's each have two 3.2GHz "IBM PowerXCell 8i CPU's, where each CPU has 1 Power Processing Unit (PPU) and 8 Synergistic Processing Units (SPU), and 32GB of RAM per node. The Intel nodes have two 2.53GHz 4core Xeon X5550 CPU's with 48GB of RAM per node and 3 contain Nvidia 9800GT video cards.

Please note that this cluster is not a production cluster and is only accessible to selected users.

Login

First login via ssh with your scinet account at login.scinet.utoronto.ca, and from there you can proceed to arc01 which is currently the gateway machine.

Compile/Devel/Compute Nodes

Cell

You can log into any of 12 nodes blade[03-14] directly to compile/test/run Cell specific or OpenCL codes.

See the Cell Devel Info page for Cell specific details.

Nehalem (x86_64) & GPU

You can log into any of 8 nodes cell-srv[01-08] directly however each of the nodes have differing configurations.

  • cell-srv01 - login node & nfs server, GigE connected
  • cell-srv[02-05] - no GPU, GigE connected
  • cell-srv[06-07] - 1x NVIDIA 9800GT GPU, Infiniband connected
  • cell-srv08 - 2x NVIDIA 9800GT GPU, GigE connected

See the GPU Devel Info page for GPU specific details.
