Adapted from the 0.9 libtopology release: it was mostly the top of
hwloc 0.9.1 has been released today.
hwloc provides a portable abstraction (across OS, versions,
architectures, ...) of the hierarchical topology of modern
architectures. It primarily aims at helping high-performance computing
applications with gathering information about the hardware so as to
exploit it accordingly and efficiently.
hwloc provides a hierarchical view of the machine, NUMA memory nodes,
sockets, shared caches, cores and simultaneous multithreading. It also
gathers various attributes such as cache and memory information.
hwloc supports the following operating systems:
* Linux (including old kernels not having sysfs topology information, with
knowledge of cpusets, offline cpus, and Kerrighed support)
* OSF/1 (aka. Tru64)
* For other OSes, only the number of processors is available for now.
hwloc can be download from
hwloc is available under the BSD license.
