[UR] Bump UR version and enable dynamic linking with UMF

[igchor]

Testing PR for: https://github.com/oneapi-src/unified-runtime/pull/1430

[jsji]

@igchor Does this mean that we will be requiring ANYONE who use UR to install libhwloc on Linux and hwloc-win64-build-2.10.0 on windows? Can we somehow detect these, and don't switch to dynamic linking if these libs are not installed?

Yes, that's correct (although the minimum required version is 2.3.0). The hwloc is required not because we link dynamically with UMF but because I've bumped UMF version we are using. This new UMF version has a dependency on hwloc which cannot be disabled. Will this be a problem for intel/llvm?

[jsji]

This new UMF version has a dependency on hwloc which cannot be disabled. Will this be a problem for intel/llvm?

Thanks @igchor for the clarification. Installing hwloc in CI/containers won't be a problem. But that also means sycl compilers and DPC++ will have to add a dependency to hwloc? If so, I think we have to update quite a bunch of documents to reflect that? Is that really what we want?

FYI. @stdale-intel .

[stdale-intel]

@jsji you are correct on both ends. @uditagarwal97 updated the Windows CI machines, and Linux containers. Docs and other things are being updated to reflect this as well.

[igchor]

But that also means sycl compilers and DPC++ will have to add a dependency to hwloc?

Yes, and there's already been a discussion about how to handle this for DPC++.

If so, I think we have to update quite a bunch of documents to reflect that? Is that really what we want?

@jsji do you want me to update any docs in intel/llvm in this PR? if yes, could you let me know which ones should I update?

Thanks @igchor . I think @stdale-intel mentioned that "Docs and other things are being updated to reflect this as well." , not sure who is doing that, but I guess someone is already taking care of that.

[stdale-intel]

@igchor if you can take care of the intel/llvm doc PR that would be awesome!

I'd start with editing https://github.com/intel/llvm/blob/sycl/sycl/doc/GetStartedGuide.md. But i'll see if there is other docs as well.

Done. Please let me know if I should update anything else.

[igchor]

@intel/llvm-gatekeepers, this PR is almost ready (I expect the required change to UR to be merged soon). Could you please let me know if everything looks good? Since this PR adds a new dependency on hwloc for sycl I would like to make sure this is fine and will not cause any issues (this was already reviewed by @stdale-intel a while ago).

We found out that hwloc, sets ZES_ENABLE_SYSMAN=1 in library ctor (ref: https://github.com/oneapi-src/level-zero/issues/36). One test (get_info_aspect.cpp) had to be fixed because of that. Will this cause any other problems?

[aelovikov-intel]

Awaiting @stdale-intel 's confirmation that downstream infrastructure has been updated to have hwloc installed on the systems before approving.

[pbalcer]

@intel/llvm-gatekeepers this is ready for merge from our side. The HIP failure is unrelated and is affecting all other PRs.

[martygrant]

@pbalcer this is waiting on approvals from intel/dpcpp-devops-reviewers, intel/dpcpp-doc-reviewers, and/or intel/llvm-reviewers-runtime

[kswiecicki]

@pbalcer this is waiting on approvals from intel/dpcpp-devops-reviewers, intel/dpcpp-doc-reviewers, and/or intel/llvm-reviewers-runtime

@martygrant, since @sarnex and @uditagarwal97 have given their approval, I believe this is ready to be merged

[sarnex]

Don't we still need dpcpp-doc-reviewers?

[kswiecicki]

Don't we still need dpcpp-doc-reviewers?

I'm not sure, @martygrant said and/or , we can wait for intel/dpcpp-doc-reviewers if it's necessary.

[sarnex]

The CI seems to be saying and, so @intel/dpcpp-doc-reviewers can someone please review this? Just a apt-get command change.

[igchor]

@intel/llvm-gatekeepers this is ready for merge, I belive we have all the required approvals now

@igchor, this PR broke our post-commit, could you please take a look? https://github.com/intel/llvm/actions/runs/10106492701

~~This needs to be fixed by @intel/dpcpp-devops-reviewers by doing brew install hwloc on the mac runners.~~ No, I just looked at the mac workflow, we can it fix ourselves. Sorry for the false alarm. PR coming.

[jsji]

intel/llvm and downstream infra has been updated to have required dependancies (hwloc)

Note this is NOT true, it turns out that we haven't have hwloc installed in ANY of our internal build system, so I am going to revert this in sycl-web first to unblock pulldown. This means this (and any new UR changes) will NOT be pulldown into downstream until we get the internal build system fixed , I have contacted our infrastructure team, hopefully they can help to install it ASAP.
