PathScale EKOPath 5.0 Beta Compiler Performance

PathScale's compiler remains slower than GCC and LLVM/Clang for VP8 video encoding,

The PathScale compiler also was far behind GCC and LLVM/Clang when it came to the Himeno Poisson Pressure Solver. EKOPath 5.0 didn't help PathScale but experienced a slight performance loss with the beta compiler.

There isn't much to see out of Parallel BZIP2 Compression.

PathScale's Linux compiler was slightly slower than GCC and LLVM/Clang for MP3 encoding.

The PathScale EKOPath 5.0 beta compiler suite for the C/C++ benchmarks used in this article was successful in building more software correctly than under PathScale 4.0. PathScale's compiler also had a few performance wins itself while for the most part it was just competitive (or slightly behind) GCC and LLVM/Clang. Even so, the performance of this compiler isn't too shabby considering that it doesn't have the wide scale adoption and development support as seen by the GNU Compiler Collection and LLVM/Clang. It continues to prove interesting to follow the ongoing work of PathScale's compiler activities.
