OpenACC Data Management

OpenACC Data Management
Thursday, May 28, 2020

On-site participation will be held at the following sites:

ORNL Building 5100, Room 128 (JICS Auditorium) 1:00 PM – 3:00 PM (ET)
NERSC Building 59 (Shyh Wang Hall), Room 4102 10:00 AM – 12:00 PM (PT)

NVIDIA will present “OpenACC Data Management” on Thursday, May 28, 2020. This event is part 2 of a 3-part OpenACC Training Series that NVIDIA will deliver in 2020.

OpenACC is a user-driven directive-based performance-portable parallel programming model designed for scientists and engineers who are interested in porting their codes to a wide variety of heterogeneous HPC hardware platforms and architectures.

Since heterogeneous HPC systems utilize accelerators with their own onboard memory, we need to learn how to manage our data. OpenACC provides a number of directives for doing so. In this module, we will present these directives, apply them to our example code, and show the performance impact on Summit. After the presentation, there will be a hands-on session where participants can complete example exercises meant to reinforce the presented concepts.

In-Person Participation
OLCF and NERSC will both hold in-person events for each part of the series, where participants can watch the presentations and get help from experts during the hands-on sessions. In-person participants without current Summit or Cori-GPU access will be given temporary accounts to work on the examples.

The deadline for in-person registration is May 14, 2020.

Remote Participation
Remote participants can watch the presentations via web broadcast and will have access to the training exercises, but temporary access to the compute systems will be limited as follows:

  • Current NERSC users will have Cori-GPU access temporarily added to their accounts.
  • Temporary Summit access will not be available for remote participants.

NOTE: Registration is required for both in-person and remote participation. To register, please submit the form below.
