RDMA socket support in the JDK

[Kasper Nielsen]

Hi,

I just saw a JEP draft for RDMA socket support in the JDK. Anyone got any experience with it?

JEP Draft: https://bugs.openjdk.java.net/browse/JDK-8203434

JDK Bug with webreg: https://bugs.openjdk.java.net/browse/JDK-8195160

Java 7 introduced Sockets Direct Protocol ... a mechanism to achieve RDMA across Linux JVMs that had specific OFED device drivers  and Infiniband ($$) as the physical network between JVMs’  NICs.

With Intel’s gift of iWarp to OFED ... enabling RDMA over Ethernet ... maybe this JEP could drive development of an SDP capability that could deliver RDMA to the Java masses (Ethernet) .. and not the Java ultra-rich (Infiniband) ?
