In this presentation, Doug Miles from Nvidia describes the new features and performance gains in the PGI 2014 release. “The use of accelerators in high performance computing is now mainstream,” said Douglas Miles, director of PGI Software at Nvidia. “With PGI 2014, we are taking another big step toward our goal of providing platform-independent, multi-core and accelerator programming tools that deliver outstanding performance on multiple platforms without the need for extensive, device-specific tuning.” Watch the video presentation: http://insidehpc.com/2014/02/14/slidecast-new-pgi-2014-release-adds-openacc-2-0-features-x64-performance-gains/
