[Cbe-oss-dev] elaboration of Axon driver?

[Marcus G. Daniels]

Hi,

I've been using the Axon driver on Roadrunner IBM triblades and I'm 
wondering if any thought has been given to supporting DAPL?   In 
particular, I'm interested in marshaling function calls with complex 
types as arguments, perhaps with RDMA/RPC.  Since most of the numerics 
work on Roadrunner is done on the SPUs of the Cell processors, and is 
very specialized for performance, it's appealing to me keep the Opteron 
side of the code relatively abstract.  An Axon implementation of MPI 
would be another option, although the use case I have in mind is 
factoring monolithic codes to run on multiple tiers of the system, with 
MPI on the outside (across the cluster).   Also, simple message passing 
can be done reasonably well with DaCS anyway.  I'd like to be able to 
break up codes such that some pieces could be RPCed to the PPU of the 
Cell. 

Wondering if anyone has thought about these issues.

Regards,

Marcus Daniels
