ENZO -- an alternative to CUDA and OpenCL @

Reposting article from HPCwire:
HPCwire: PathScale Looks to One-Up CUDA, OpenCL with New GPU Compiler
Using the open source NVIDIA graphics driver -- Nouveau,
which is included in the Linux kernel -- PathScale created a fork off the
source code with high performance computing in mind. PathScale also
managed to recruit most of the talent from the driver project. PathScale's CTO, Bergström,
says the team was able to reverse engineer the NVIDIA ISA, register
details, and device exception handling. With that knowledge, they set
out to rewrite the code generator (compiler back-end), driver, and
runtime, focusing on improved memory management, error handling,
security and HPC-specific features, and performance.
