This work is coming due to the new Heterogeneous System Architecture Foundation .
The slides that Bridgman references can be found at SlideShare.net. The page cited is entitled “AMD’s Open Source Commitment To HSA” and says “We will open source our Linux execution and compilation stack.” This is being done to jumpstart the HSA ecosystem, allow a single shared implementation where appropriate, and to enable university research in all areas.
The Heterogeneous System Architecture Foundation is poised to “define and promote an open, standards-based approach to heterogeneous computing that will provide a common hardware specification and broad support ecosystem to make it easier for software developers to deliver innovative applications that can take greater advantage of today’s modern processors.” The HSA Foundation goes without Intel’s support. The HSA press release can be read at AMD.com for more details as to what’s been announced thus far.
