Debugging RCCE application with gdb on many cores

Hi,

I have came accross threads where example is given of how to use gdb with scc, but the example only uses one core. so my question: is it possible to use it with >1 core. and if yes can some one give a simple example?

Thank you

Nil

I believe that is not possible. Each core is independent (cores do not share any state), so "collective" debugging seems impossible.

Wouldn't that be true for MPI as well? But we can do that in MPI so I think there should be a way for RCCE too.

Well,it's not impossible, but I don't know of anyone who has done collective debugging with SCC cores. You might take a look at
http://www.eclipse.org/ptp/

The ptp stands for parallel tools platform and the last I heard (it's been a while) that group has been investigating many-core debugging.
