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.

Login

First login via ssh with your scinet account at login.scinet.utoronto.ca, and from there you can proceed to cell-srv01 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.

Local Disk

This test cluster currently cannot see the global /home and /scratch space so you will have to copy (scp,etc..) your code to a separate local/home dedicated for this cluster. Also initially you will probably want to copy/modify your scinet .bashrc, .bashrc_profile, and .ssh directory onto this system.
