The general CentOS collaboration mechanism is a bit unclear to me, to be honest. It doesn't seem to be like Fedora, where anyone can create an account and try to get a package into the distribution. Not that this is something I expect as part of this effort; the focus should be on building existing stuff in new and exciting ways. Anyway, here are some concrete items for collaboration: I hope that performance experts will be able to share benchmarking results based on the optimized builds the SIG produces, and investigate glitches we encounter. Any kind of testing will help. Some packages will fail to build with -march=x86-64-v3. Triaging these failures, reporting them upstream etc., will be required, and that part does not require any special privileges (as long as the build logs and buildroots are public, which I expect them to be). We would benefit from expert guidance on GCC parameter defaults, like preferred vector sizes for certain operations. Once we explore delivery mechanisms, exploring how builds can be consumed by end users in custom CI systems etc., and feedback on that will be helpful. Do you think this provides some clarification? > 2) There are existing Intel people working in the Hyperscaler SIG on > some optimized libraries.

Is it more than just zlib? <https://cbs.centos.org/koji/packages?tagID=2620> zlib upstream doesn't take architecture optimization patches, and maintaining the downstream patches (some of them are in CentOS proper already) is an ongoing hassle. I've looked at <https://sigs.centos.org/hyperscale/content/repositories/main/> That seems to be focus on CentoS 8 Stream. The package versions in 9 are actually higher than what's mentioned there. > I am happy to act as the Board sponsor for this SIG and I believe we > should work through any missing pieces or logistics before next > month's Board meeting.
