Changelog for hwloc-2.8.0-1.3.x86_64.rpm :

* Fri Jul 29 2022 Callum Farmer - Add libXNVCtrl support on TW
* Mon Jul 11 2022 Dirk Müller - update to 2.8.0:
* API + Add HWLOC_TOPOLOGY_FLAG_NO_DISTANCES, _NO_MEMATTRS and _NO_CPUKINDS to reduce the overhead when unneeded. + Add separate Read/Write Bandwidth/Latency memory attributes and implement them on Linux.
* Backends + NUMA nodes may now have a subtype such as DRAM, HBM, SPM, or NVM on heterogeneous memory platforms on Linux. - Add DAXType and DAXParent attributes on Linux to tell where a DAX device or its corresponding NUMA node come from (SPM for Specific-Purpose or NVM for Non-Volatile Memory). + Detect heterogeneous caches in hybrid CPUs on MacOS X, thanks to Paul Bone for the help. + Max frequencies are not ignored in Linux cpukinds anymore (they were ignored in hwloc 2.7.0), but they may be slightly adjusted to avoid reporting hybrid CPUs because Intel Turbo Boost Max 3.0. - See the documentation of environment variable HWLOC_CPUKINDS_MAXFREQ. + Hardwire the PCI locality of HPE Cray EX235a nodes.
* Tools + lstopo and other tools may now load Linux and x86 cpuid topology files from a tarball. + lstopo may now replace the P# and L# index prefixes with custom strings thanks to --os-index-prefix and --logical-index-prefix options.
* Misc + Add --disable-readme to avoid regenerating the top-level hwloc README file from the documentation.
* Fri Apr 08 2022 Dirk Müller - update to 2.7.1:
* Workaround crashes when virtual machines report incoherent x86 CPUID information about numbers of cores and threads. Thanks to Peter Bense for the report.
* Use setenv() instead of putenv() when trying to force enable oneAPI L0 support, to avoid issues with applications that touch the environment, thanks to Josh Hursey for the patch.
* Add some warnings at the end of configure when GPU libraries are missing on the system or their path is missing in the environment.
* Backends + Add support for NUMA nodes and caches with more than 64 PUs across multiple processor groups on Windows 11 and Windows Server 2022. + Group objects are not created for Windows processor groups anymore, except if HWLOC_WINDOWS_PROCESSOR_GROUP_OBJS=1 in the environment. + Expose \"Cluster\" group objects on Linux kernel 5.16+ for CPUs that share some internal cache or bus. This can be equivalent to the L2 Cache level on some platforms (e.g. x86) or a specific level between L2 and L3 on others (e.g. ARM Kungpeng 920). Thanks to Jonathan Cameron for the help. - HWLOC_DONT_MERGE_CLUSTER_GROUPS=1 may be set in the environment to prevent these groups from being merged with identical caches, etc. + Improve the oneAPI LevelZero backend: - Expose subdevices such as \"ze0.1\" inside root OS devices (\"ze0\") when the hardware contains multiple subdevices. - Add many new attributes to describe device type, and the numbers of slices, subslices, execution units and threads. - Expose the memory information as LevelZeroHBM/DDR/MemorySize infos. + Ignore the max frequencies of cores in Linux cpukinds when the base frequencies are available (to avoid exposing hybrid CPUs when Intel Turbo Boost Max 3.0 gives slightly different max frequencies to CPU cores). - May be reverted by setting HWLOC_CPUKINDS_MAXFREQ=1 in the environment.
* Tools + Add --grey and --palette options to switch lstopo to greyscale or white-background-only graphics, or to tune individual colors.
* Build + Windows CMake builds now support non-MSVC compilers, detect several features at build time, can build/run tests, etc. Thanks to Michael Hirsch and Alexander Neumann .
* Sun Dec 05 2021 Dirk Müller - update to 2.6.0:
* Backends + Expose two cpukinds for energy-efficient cores (icestorm) and high-performance cores (firestorm) on Apple M1 on Mac OS X. + Use sysfs CPU \"capacity\" to rank hybrid cores by efficiency on Linux when available (mostly on recent ARM platforms for now). + Improve HWLOC_MEMBIND_BIND (without the STRICT flag) on Linux kernel >= 5.15: If more than one node is given, the kernel may now use all of them instead of only the first one before falling back to others. + Expose cache os_index when available on Linux, it may be needed when using resctrl to configure cache partitioning, memory bandwidth monitoring, etc. + Add a \"XGMIHops\" distances matrix in the RSMI backend for AMD GPU interconnected through XGMI links. + Expose AMD GPU memory information (VRAM and GTT) in the RSMI backend. + Add OS devices such as \"bxi0\" for Atos/Bull BXI HCAs on Linux.
* Tools + lstopo has a better placement algorithm with respect to I/O objects, see --children-order in the manpage for details. + hwloc-annotate may now change object subtypes and cache or memory sizes.
* Build + Allow to specify the ROCm installation for building the RSMI backend: - Use a custom installation path if specified with --with-rocm=. - Use /opt/rocm- if specified with --with-rocm-version= or the ROCM_VERSION environment variable. - Try /opt/rocm if it exists. - See \"How do I enable ROCm SMI and select which version to use?\" in the FAQ for details. + Add a CMakeLists for Windows under contrib/windows-cmake/ .
* Documentation + Add FAQ entry \"How do I create a custom heterogeneous and asymmetric topology?\"
* Sat Jul 17 2021 Dirk Müller - update to 2.5.0: + Add hwloc/windows.h to query Windows processor groups. + Add hwloc_get_obj_with_same_locality() to convert between objects with same locality, for instance NUMA nodes and Packages, or OS devices within a PCI device. + Add hwloc_distances_transform() to modify distances structures. - hwloc-annotate and lstopo have new distances-transform options. + hwloc_distances_add() is replaced with _add_create() followed by _add_values() and _add_commit(). See hwloc/distances.h for details. + Add topology flags to mitigate binding modifications during hwloc discovery, especially on Windows: - HWLOC_TOPOLOGY_FLAG_RESTRICT_TO_CPUBINDING and _MEMBINDING restrict discovery to PUs and NUMA nodes inside the binding. - HWLOC_TOPOLOGY_FLAG_DONT_CHANGE_BINDING prevents from ever changing the binding during discovery. + Add a levelzero backend for oneAPI L0 devices, exposed as OS devices of subtype \"LevelZero\" and name such as \"ze0\". - Add hwloc/levelzero.h for interoperability between converting between L0 API devices and hwloc cpusets or OS devices. + Expose NEC Vector Engine cards on Linux as OS devices of subtype \"VectorEngine\" and name \"ve0\", etc. Thanks to Anara Kozhokanova, Tim Cramer and Erich Focht for the help. + Add a NVLinkBandwidth distances structure between NVIDIA GPUs (and POWER processor or NVSwitches) in the NVML backend, and a XGMIBandwidth distances structure between AMD GPUs in the RSMI backends. - See \"Topology Attributes: Distances, Memory Attributes and CPU Kinds\" in the documentation for details about these new distances. + Add support for NUMA node 0 being offline in Linux, thanks to Jirka Hladky. + Add --with-cuda-version= or look at the CUDA_VERSION environment variable to find the appropriate CUDA pkg-config files. Thanks to Stephen Herbein for the suggestion. - Also add --with-cuda= to specify the CUDA installation path manually (and its NVML and OpenCL components). Thanks to Andrea Bocci for the suggestion. - See \"How do I enable CUDA and select which CUDA version to use?\" in the FAQ for details. + lstopo now has a --windows-processor-groups option on Windows. + hwloc-ps now has a --short-name option to avoid long/truncated command path. + hwloc-ps now has a --single-ancestor option to return a single (possibly too large) object where a process is bound. + hwloc-ps --pid-cmd may now query environment variables, including MPI-specific variables to find out process ranks.
* Tue Mar 16 2021 Dirk Müller - update to 2.4.1:
* Fix AMD OpenCL device locality when PCI bus or device number >= 128. Thanks to Edgar Leon for reporting the issue. + Applications using any of the following inline functions must be recompiled to get the fix: hwloc_opencl_get_device_pci_busid() hwloc_opencl_get_device_cpuset(), hwloc_opencl_get_device_osdev().

* Add support for Linux 5.3 new sysfs cpu topology files with Die information.
* Add support for Intel v2 Extended Topology Enumeration in the x86 backend.
