• Package: umf
• Version: 1.1.0
• Source: https://github.com/oneapi-src/unified-memory-framework

Compiles Intel's oneAPI Unified Memory Framework into libumf.so (headers + CMake config, no Python bindings). Upstream's PyPI umf wheel is Intel's own closed-redistribution x86_64/win_amd64 build with no sdist, so this builds the Apache-2.0 UMF source directly instead, same shape as the tbb/tcmlib ports.

No upstream CI builds this wheel; the shipped libumf.so embeds its own build's CMake flags as a debug string, which this mirrors exactly (only UMF_BUILD_SHARED_LIBRARY, UMF_BUILD_LEVEL_ZERO_PROVIDER and UMF_BUILD_CUDA_PROVIDER on). Those two GPU providers only dlopen() the vendor runtime at call time and compile against header-only fetched repos, so they stay fully portable.

Differs from upstream

• Builds HWLOC 2.14.0 from source and bundles it - UMF requires it and it isn't a manylinux-portable system dependency, same as the tcmlib port.
• No source patches. The test container's docker run adds --cap-add=SYS_PTRACE (see below), two gtest cases are skipped via GTEST_FILTER (see below), and the smoke-install step sets PIP_EXTRA_INDEX_URL (see below).

Testing

• Runs UMF's own ctest suite before packaging (46 CTest targets) - 46/46 passing on riscv64 CI.
• ctypes smoke test: load libumf.so, call umfGetCurrentVersion(), assert the expected value - passing on riscv64 CI.

riscv64 CI: three issues found and fixed/documented in sequence, now fully green

The first riscv64 CI run (job) built and installed cleanly but ctest failed 8 of test_provider_os_memory's 50 gtest cases, all under osProviderTest/umfIpcTest.*/disjoint_w_params_0_OS_HostMemoryAccessor.

First attempt (reverted). A padding/memcmp() theory about the IPC opened-handle cache key looked plausible from the source alone and was patched + pushed, but a fresh CI run reproduced the exact same 8 failures unchanged. Re-reading ipcFixtures.hpp shows the failing line in BasicFlow is the first of its two umfOpenIPCHandle() calls, not a cache-hit second lookup as the patch's write-up claimed — so that theory doesn't even apply to this failure. The patch has been reverted.

Real root cause (IPC). All 8 failing tests call umfOpenIPCHandle(); every IPC test that doesn't call it passes. os_open_ipc_handle()'s anonymous-fd path calls utils_duplicate_fd() → pidfd_getfd(2) to duplicate the allocation's fd. Docker's default seccomp profile only allows pidfd_getfd with CAP_SYS_PTRACE; without it the syscall returns EPERM, which utils_errno_to_umf_result() maps to UMF_RESULT_ERROR_INVALID_ARGUMENT (3) — the exact code, and the exact FATAL "ptr != NULL" close-time abort from freeing a never-opened cache entry at pool teardown, seen in every failure:

/work/test/ipcFixtures.hpp:543: Failure
Expected equality of these values:
  ret
    Which is: 3          // UMF_RESULT_ERROR_INVALID_ARGUMENT
  UMF_RESULT_SUCCESS
    Which is: 0
[FATAL UMF] umfMemoryProviderCloseIPCHandle: UMF check failed: (ptr != NULL)

This matches a known, closed upstream issue (oneapi-src/unified-memory-framework#979) about pidfd_getfd failing under restricted ptrace. Fix: docker run --cap-add=SYS_PTRACE on the test container, which also lifts the Yama ptrace_scope restriction the same syscall is subject to. No UMF source change needed — this was a test-environment gap, not a library bug.

Second, independent failure (SIGBUS), first scoped too narrowly. The same CI run also showed test_provider_tracking_fixture_tests crashing with Bus error in TrackingProviderPoolTest/umfPoolTest.multiThreadedpow2AlignedAlloc/proxy_provider_from_pool (concurrent power-of-two-aligned allocation through a doubly-nested tracking-provider stack over a file-backed mmap provider). That looked concurrency-specific, so only that one parameterized case was skipped via GTEST_FILTER. A later CI run on the same commit (after the ptrace fix was applied) crashed instead in the plain, single-threaded pow2AlignedAlloc/proxy_provider_from_pool case — which calls the exact same pow2AlignedAllocHelper (test/poolFixtures.hpp) — so the crash is not threading-specific after all; the skip has been widened to both parameterizations. Reviewed provider_file_memory.c's coarse suballocator locking, provider_tracking.c's atomics, and critnib's tagged-pointer bit — found no docker/seccomp explanation and no single obvious bug without riscv64 hardware to reproduce and debug interactively. Every other test on this fixture (non-aligned alloc/free, single- and multi-threaded) passes. Per the port playbook's last-resort rule, both parameterized cases are skipped via GTEST_FILTER with a comment pointing at the gotcha, rather than blocking the rest of the port on an unreproducible bug or overclaiming a root cause that isn't there. Flagged for anyone with riscv64 hardware access to pick up.

Third issue (registry), found once the first two were confirmed fixed. With both fixes in place, the next CI run's ctest passed 100% (46/46, ~137s), confirming both. That run then failed at the final smoke-install step, pip install dist/*.whl, with No matching distribution found for tcmlib>=1.5 — the wheel's own install_requires, which only has a riscv64 build on our own registry (pypi.riseproject.dev), not public PyPI. This self-driven docker run never inherits the PIP_EXTRA_INDEX_URL wiring a CIBW_ENVIRONMENT-based port gets for free (the gotcha 30/422 pattern), and the workflow's one hand-written pip install line on this path had never set it. Fix: PIP_EXTRA_INDEX_URL=https://pypi.riseproject.dev/simple/ on that one line.

Confirmed green on the next CI run (job): ctest 46/46, wheel installs, smoke test prints smoke test OK: umfGetCurrentVersion() = 65536, wheel artifact uploaded.

License: Apache-2.0 (UMF's own LICENSE.txt); wheel also bundles HWLOC (BSD-3-Clause, its own COPYING file), since the build compiles and ships it as a runtime dependency.

Built and smoke-tested locally on x86_64.
