Download Hardware Locality 1.11.0

View the hierarchical topology of modern architectures

Hardware Locality (hwloc) software package provides a portable abstraction (across OS, versions, architectures, ...) of the hierarchical topology of modern architectures, including NUMA memory nodes, sockets, shared caches, cores and simultaneous multithreading. It also gathers various system attributes such as cache and memory information as well as the locality of I/O devices such as network interfaces, InfiniBand HCAs or GPUs. It primarily aims at helping applications with gathering information about modern computing hardware so as to exploit it accordingly and efficiently.

Whats new in version 1.11.0:
API:
• Add hwloc_obj_type_sscanf() to extend hwloc_obj_type_of_string() with type-specific attributes such as Cache/Group depth and Cache type. hwloc_obj_type_of_string() is moved to hwloc/deprecated.h.
• Add hwloc_linux_get_tid_last_cpu_location() for retrieving the last CPU where a Linux thread given by TID ran.
• Add hwloc_distrib() to extend the old hwloc_distribute[v]() functions. hwloc_distribute[v]() is moved to hwloc/deprecated.h.
• Don't mix total and local memory when displaying verbose object attributes with hwloc_obj_attr_snprintf() or in lstopo. Backends:
• Add CPUVendor, CPUModelNumber and CPUFamilyNumber info attributes for x86, ia64 and Xeon Phi sockets on Linux, to extend the x86-specific support added in v1.8.1.
• Add many CPU- and Platform-related info attributes on ARM and POWER platforms, in the Machine and Socket objects.
• Add CUDA info attributes describing the number of multiprocessors and cores and the size of the global, shared and L2 cache memories in CUDA OS devices.
• ...
