Charm++ parallel programming system

[Michael Robson <mprobson AT illinois.edu>]

Hello Adeesha,

In order to use the use the GPU functionality in charm you need to build a cuda version. So you should modify your build line to the following:

./build charm++ multicore-linux-x86_64 cuda -j16

We're working on improving the usability of our GPU framework so please let me know if you run into any more difficulties.

Sincerely,

Michael Robson

Hi,

I am a phd student in University of Florida. I am trying to build charm++ to use with CUDA. But once I tried to run example cuda programs it gives me an errors saying that 

"undefined reference to `wrQueue' "

"undefined reference to `enqueue(workRequestQueue*, workRequest*)'"

undefined reference to `kernel_stream' .

When I was trying to build hybridAPI files which includes wr.h file it gives me some other include errors(cklists.h: No such file or directory).

I think I built charm++ using wrong parameters. I used 

./build ./build charm++  multicore-linux64 -j16

Could you please tell me what parameters should I use to build charm++ to run with CUDA.

Or is this because of some other thing that I have to do.

Any help on this is highly appreciated.

Thank you very much.

Best regards,

Adeesha.
