wheels: compress CUDA fat binaries to fit EB under PyPI 320 MB limit#292
Merged
Conversation
EB adds ~100 MB of template instantiations to the AMReX static library. With 3 CUDA architectures (75-real, 80-real, 90-virtual), the fat binary exceeds PyPI's 320 MB ceiling. Adding -Xfatbin --compress-all to both the AMReX build and the OpenImpala wheel build compresses the embedded SASS/PTX with negligible runtime decompression cost (~30-50% reduction in device code size).
