The Cray User Group was established to facilitate collaboration and information exchange in the high-performance computing (HPC) community. The OpenACC organization is aligned with this mission.
For over a decade, the OpenACC Organization has been dedicated to helping the research and developer community advance science by expanding their accelerated and parallel computing skills. We have 3 areas of focus: participating in computing ecosystem development; providing training and education; and developing the OpenACC specification
