NOTE: THIS SYSTEM IS NO LONGER AVAILABLE

The Cell Development nodes are IBM QS22's each with 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.

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.

Programming Frameworks

Currently there are two programming frameworks to use. The Cell SDK is the most full featured and "supported" but is architecture specific, whereas the OpenCL should allow code portability to other accelerators (like GP-GPU's) however is from IBM alphaworks so should be considered beta.

OpenCL

Examples are in

/usr/share/doc/OpenCL-0.1-ibm

Cell SDK

Demos, examples, and build details available in

/opt/cell/sdk/

Compilers

NOTE: gcc has been replaced, use ppu-gcc for most cases where gcc whould be used

ppu-gcc -- GNU GCC PPC compiler

spu-gcc -- GNU GCC SPU compiler

xlcl -- IBM XL OpenCL compiler

MPI

Still a work in progress.
