A
A subset of the QLogic InfiniBand Fabric Suite, the enablement tools, are
offered with this release.
Two separate SCSI RDMA Protocol (SRP) modules are provided: the
standard OpenFabrics (OFED) SRP, and QLogic SRP.
QLogic MPI supports running exclusively on a single node without the
installation of the HCA hardware.
OpenMPI and MVAPICH libraries built with the GNU, PGI, PathScale™, and
Intel
®
compilers are available, with corresponding mpitests RPMs. You
can use mpi-selector to choose which MPI you want. These all run over
PSM.
4K Maximum Transfer Unit (MTU) is supported and is on by default. To take
advantage of 4KB MTU, use a switch that supports 4KB MTU. QLogic also
supports 2KB switches, and 4KB MTU switches configured for 2KB MTU.
QLogic switches with firmware version 4.1 or later are recommended.
The Lustre
®
cluster filesystem is supported.
