[Llvm-bgq-discuss] Problems with OpenMP in C code

[Hal Finkel]

Hi Erik,

There are newer nightly builds. Please see http://www.mcs.anl.gov/~hfinkel/bgclang/ (instructions on how to install are here: http://trac.alcf.anl.gov/projects/llvm-bgq)

I'm also putting together a new bgclang release based on the upcoming 3.8 release. That version will be based on the upstream OpenMP support (instead of on the Intel OpenMP branch), and so the OpenMP support should be more robust.

Thanks again,
Hal
