This feature introduces a Solaris driver for the fourth generation of InifiniBand (IB) HCA chips from Mellanox, Ltd. The hermon driver provides IB support for SDR, DDR, and QDR chips for conventional HCAs, EMs, and NEMs for blade environments.
The hermon driver enables higher bandwidth and lower latency in IB transmissions, compared to previous generations of the IB product. The higher bandwidth and lower latency are most important in high-performance computing (HPC) applications, though the increase in performance is advantageous in all environments.
In addition, the uDAPL library, a critical underpinning of the MPI library, is updated to work with this driver, providing optimal performance with MPI-based applications.
