Andreas
Thanks! We already have several external test cases in pocl's build
mechanism, and adding PyOpenCL seems like a worthwhile goal, requiring only
a bit of autoconf magic. Your instructions above indicate that the head in
the git repository is a good version to try?
In pocl, development is mostly focussed on code generation, in particular
automatic vectorization, parallel correctness, and efficiency. The OpenCL
API is secondary, and is mostly improved or implemented as necessary. Are
there any functions that are currently either missing or are not working
correctly that would be particularly important to you? Is e.g.
clCreateProgramWithBinary important? Do you also have feedback about pocl's
performance? Do you maybe have a set of benchmarks?
Since you tested pocl, it seems to be working for you at least in a
rudimentary manner. We are currently preparing a new release, pocl 0.8, to
coincide with the upcoming LLVM 3.3 release. Did you use LLVM 3.3? Do you
want to test the pocl 0.8 release branch with LLVM 3.3 on your machine, and
add a table entry to <
https://sourceforge.net/apps/mediawiki/pocl/index.php?title=ReleaseTestLog>?
I am trying to cover a wide range of architectures there, but an additional
data point for one of the mainline architectures (assuming you are using
x86_64) is always good.
