Memory-to-Memory Data Throughput that Bypasses the OS Is the Secret October 31, 2011,

In his post Enabling HPC with InfiniBand in Java Applications Ricardo Ferreira argues that the maturity and e bandwidth advantages of InfiniBand's give it an edge over Fibre Channel and Ethernet as the choice for a network fabric. He argues that InfiniBand's capability to move data directly from the memory of one computer to another, bypassing the operating systems of both in the operation, gives it a performance advantage in HPC settings. Ferreria discusses the Sockets Direct Protocol (SDP), the networking protocol developed to support stream connections over InfiniBand fabric and then goes on to write about creating a configuration file for SDP and enabling the SDP protocol. It is the enabling of SDP support in InfiniBand, he concludes, that is the key to maximizing the performance of Java applications.
