* Package name : libpsm2 Version : 4.0 Upstream Author : 01org <webmas...@linux.intel.com> * URL : https://github.com/01org * License : GPL, BSD Programming Lang: C Description : PSM2 runtime, dev and compatibility libraries for Intel Omni-Path libpsm2 provides the Performance Scaled Messaging API for user-space applications that wish to perform high-bandwidth, low-latency RDMA communications (e.g. openmpi, mvapich2). The predecessor of PSM2 is the PSM API provided by libpsm-infinipath1. Intel Omni-Path hardware and the supporting hfi1 kernel module require use of PSM2. libpsm2 will be able to coexist on a system that has libpsm-infinipath1 installed. It is not a replacement for libpsm-infinipath1. A host that has PSM and PSM2 capable hardware should be able to use either API, depending upon the fabric interface needed for communications. This proposal involves multiple packages: * libpsm2 - runtime libraries for PSM2 * libpsm2-dev - development headers and linker libraries for PSM2 * libpsm2-compat - compatibility library for PSM applications The purpose of libpsm2-compat is to allow a PSM application to use hardware that requires PSM2 (e.g. Intel Omni-Path). An example of such an application is openmpi 1.6.5. By prepending the compatibility library's installation directory to LD_LIBRARY_PATH, a PSM application is able to transparently use the PSM2 API without requiring a code port or recompilation. I have been maintaining the Intel Fabric Suite for Omni-Path on Debian for the past year as an employee of System Fabric Works (SFW). SFW has adequate hardware and resources to test and maintain this package.
