LLVM source-to-source compiler for loop parallelization

Project Infrastructure LLVM Dev List Archives
#1

Hi,

I am a research scholar of Dept. of Computer Science and Engg. of Indian Institute of Technology Kharagpur.
I just want to know whether LLVM has any source-to-source compiler which automatically parallelizes a loop ?

Thanks,
Sudakshina

To my knowledge, not within LLVM.

Within my group we developed pet, a polyhedral extraction tool [1]. pet is based on clang and used to parallelize loops in the latest version of Pluto [2] (CPU parallelism) as well as in ppcg (both GPU and CPU parallelism).

Cheers,
Tobias
