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 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.
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.
