Charm++ parallel programming system

Hello Yan-Ming,

I wanted to let you know that I'm looking into this and will update you when I have a fix. Thanks for pointing this out.

Sincerely,

Michael Robson

Hi  all,

I would like to do some experiments on charm++ cuda features, I tried to run the four existing cuda examples but found that two of them are broken.

For hello and vectorAdd, they worked fine.

However I got a coredump on the overlapTestGPUManager test and  a link error on overlapTestStream. 

I compiled this charm++ build with the output from the smart build Perl script: ./build charm++ net-linux-x86_64 gcc cuda --with-production

Please tell me if I got any step wrong.
