My very special thanks go out to both these speakers for setting the stage at the meetup!!!!

Michael Wolfe’s talk (PGI)

  • True deep copy (PGI is currently working on an implementation)
  • Asynchronous feature for multicore architectures
  • Multiple devices
  • Abstractions for memory hierarchies
  • Defining how OpenACC works with devices that share part of memory such as CUDA unified memory
  • Request for examples of applications or algorithms that need to be expressed differently for GPU and CPU, to drive a discussion of how to express them more abstractly allowing the implementation (compiler and runtime) to select the appropriate implementation.

July 31 – OpenACC Scientific Application User feedback session at Oak Ridge National Laboratory (ORNL)

  • If you are using OpenACC for porting your scientific applications and have been thinking about newer directives that the specification currently lacks, talk to us!

  • Your talk doesn’t need to be formal at all. What we would like to hear about are the challenges you faced using OpenACC for your applications, newer features/directives you are thinking about and compiler bugs that you would have encountered in your porting process.

  • You are welcome to come in person to ORNL or dial in via webex.

  • Write to me (schandra@udel.edu) if you wish to be scheduled to give us your feedback.
