The Accelerator Research Cluster 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 <tt>login.scinet.utoronto.ca</tt>, and from there you can proceed to <tt>cell-srv01</tt> which 
is currently the gateway machine.

==Compile/Devel/Compute Nodes==

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

See the [[ Cell_Devel_Nodes | Cell Devel Info ]] page for Cell specific details.

=== Nehalem (x86_64) ===
You can log into any of 8 nodes '''<tt>cell-srv[01-08]</tt>''' directly.

'''<tt>cell-srv01-08]</tt>''


See [[ GPU_Devel_Nodes | GPU Devel Info ]] page for Cell specific details.

==Local Disk==

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