Researchers and developers interesting in learning how to use Intel development tools to develop for Intel Xeon Phi hardware.


Intel will be coming to the Ohio Supercomputer Center in September to provide some in-depth training on using their software development tools to develop code that performs well on Intel Xeon Phi hardware.

In the afternoon, some time is allocated for attendees to interface with Intel and OSC staff to examine attendee code and problems, and explore the tools on OSC's Ruby Transitional Cluster.
