Support UMF_NUMA_MODE_WEIGHTED_INTERLEAVE for weighted interleaving

Open honggyukim opened this issue 1 year ago • 0 comments

Hello all,

I'm Honggyu Kim from SK hynix working on HMSDK project and it's been a while. As our weighted interleaving feature was upstreamed into Linux kernel, it is now available from Linux v6.9.

I see that UMF project depends on hwloc project using HWLOC_MEMBIND_INTERLEAVE so I've also added HWLOC_MEMBIND_WEIGHTED_INTERLEAVE and upstreamed to hwloc[1] and it is supported since hwloc-2.11.0[2, 3].

So I would like to inform you that UMF project can have a new mode UMF_NUMA_MODE_WEIGHTED_INTERLEAVE for this. I know that it will be needed only when UMF depends on hwloc-2.11.0 or above though.

It may not be in a high priority but please have a look. Thanks!
