Charm++ parallel programming system

[Michael Robson <mprobson AT illinois.edu>]

Hello Robert,

I've posted a small patch here: https://charm.cs.illinois.edu/gerrit/#/c/2939/ that you can checkout that hopefully solves your problem.

I've also copied Sameer Kumar to ask whether this padding is even necessary.

It seems that the padding calculation in the PPCAtomicState struct has a bug that's causing the padding array to overflow. I currently don't have access to a PAMI machine so this is untested (but fairly minor). You should also be able to delete the offending line without a problem (pending Sameer's comments). Thanks for bringing this issue to our attention and please let us know if we can be of any more assistance.

Sincerely,

Michael

Hi,

I am trying to build charm with PAMI and SMP support on a Linux based Power8
system. I had to make some minor alterations to account for the position of
libraries but this is the build instruction I execute and which used to work in
the past.

./build charm++ pami-linux-ppc64le smp --with-production

Now I am getting some build errors related to atomic queue sizes and lots of
warnings about -Q switch. I am attaching the compilation step which breaks.

I would appreciate if you could suggest something. Happy to share more build
information. The compiler here default to XL.

Best wishes,
Robert
