Yes! Try ./autogen.sh -yaksa-depth=2​. You can try -yaksa-depth=1​ if 2 is still too slow. -- Hui ________________________________ From: Jeff Hammond via devel <[email protected]> Sent: Wednesday, August 17, 2022 1:02 AM To: MPICH <[email protected]> Cc: Jeff Hammond <[email protected]> Subject: [mpich-devel] is there a way to speedup build related to yaksuri? Is there a configure option that would allow me to avoid the compilation bottleneck in `src/backend/seq/pup/yaksuri_seqi_pup*`? I want to rebuild MPICH frequently for development purposes, and I do not care about datatype performance in this context. Some of the yaksuri objects take seconds to compile with GCC 11 at -O2 on Tiger Lake core, and there are hundreds of them.
