Can anyone recommend a debugger to work with PGF?

Hi,

there are now a number of debugging tools available for working with CUDA. Has anyone out there any experience of which ones work best with the Portland Fortran CUDA models (eg. Allinea DDT, Totalview etc.)?

Any advice greatly appreciated,

Rob.

Hi Rob,

Both Allinea and Totalview have or are just about to release debuggers for CUDA C. We have a good working relationship with both companies and hopefully in the future add support for CUDA Fortran.

Currently you can debug CUDA Fortran code in emulation mode using PGDBG.

Support for Device Emulation mode is removed in CUDA 3.1. I'm not sure if CUDA Fortran can still use it.

We still support emulation mode in CUDA Fortran.
