Tags: Proceedings , 2019 , SHARE Pittsburgh 2019

In this session, the speaker will provide an overview of Shared Memory Communications, including the Shared Memory Communications over RDMA (SMC-R) capability introduced in z/OS V2R1, as well as the newer Shared Memory Communications-Direct Memory Access (SMC-D) technology available on the z13 and higher. SMC-D with Internal Shared Memory (ISM) provides highly optimized intra-CPC communications, and is expected to provide substantial performance, throughput, response time, and CPU consumption benefits compared to standard TCP/IP communications over HiperSockets.-Gus Kassimis-IBM Corporation; Jerry Stevens-IBM Corporation
