This format could be extracted from graphite easily and could also be created in LLVM. What we need to get back into LLVM is only the new optimized schedule described e.g. as cloog like scattering functions. These can be parsed easily. The rea...

...ther tools with PCP. The main people to contact are "Sjodin, Jan" <Jan.Sjodin at amd.com> Sebastian Pop <sebpop at gmail.com> Work on PCP has stalled because Jan has left for another group. In the hort term, Tobias is right that the best way to interface tools is to use the scoplib format and library from Louis-Noel Pouchet (PoCC). In any case, work on either PCP or scoplib will be beneficial. The community of polyhedral compilation experts is small, and its openly available output is already diminished by two proprietary development projects at IBM and Reservoir Labs. I...

...external tools like LooPo (automatic parallelization), Pluto (optimization in general) or even Graphite might be used to optimize code. This could give a first impression what to expect from the polyhedral model in LLVM. There are also affords to establish an interchangeable polyhedral format (scoplib - Louis-Noel Pouchet) and to generate a polyhedral compilation package. These will allow to share/exchange optimizations between different compilers and research tools. Furthermore an external interface will enable researchers to use LLVM for their work on polyhedral optimizations. This might b...

Hi all, I have updated my GSoS proposal: "FastPolly: Reducing LLVM-Polly Compiling overhead" (https://gist.github.com/tanstar/5441808). I think the pass ordering problem you discussed early can be also investigated in this project! Is there any comment or advice about my proposal? I appreciate all your help and advice. Thanks, Star Tan Proposal:
