GPU Series: Verifying Code Correctness with PCAST

The next session in a series of workshops and tutorials on GPU computing – “Verifying Code Correctness with PCAST” – will be on Thursday, May 19, at 10 a.m. MDT. The series of one-hour sessions is for scientists, software engineers, and students in the Earth system sciences to help them prepare to use the extensive GPU-computing capabilities of the new Derecho system. The training is intended for both new and more experienced GPU programmers and requires familiarity with the UNIX shell; Fortran, C/C++, and/or Python; and typical program compilation workflows.

Topics to be covered in this session include:

• Pros and Cons of Validating Scientific Software
• Usage of Parallel Compiler Assisted Software Testing (PCAST)
  • Comparing CPU and GPU Code Execution
  • PCAST with a Golden File  
  • PCAST with OpenACC and Autocompare

As with other sessions in the series, this one will include dedicated Q&A time and some will involve interactive coding with participants. This session will involve some interactive participation so make sure you are able to access the Casper compute system prior to the event. Recent registrants will be provided log in details prior to the session.
