“…FastMPJ [17] uses Java Fast Sockets [39] and ibvdev to provide a MPI implementation for parallel systems using Java. Initially, ibvdev [18] was implemented as a low-level communication device for MPJ Express [35], a Java MPI implementation of the mpiJava 1.2 API specification. ibvdev implements InfiniBand support using the low-level verbs API and can be integrated into any parallel and distributed Java application.…”

“…This device directly implements its communication protocols on top of the Verbs interface through JNI. An initial proof-of-concept implementation of ibvdev was first integrated into the MPJ Express library [10] for internal testing purposes, but was never part of the official release. Although it was able to provide better performance than using the IPoIB protocol, the buffering layer in MPJ Express significantly limited its performance and scalability.…”

Providing high-performance inter-node communication is a key capability for running high performance computing applications efficiently on parallel architectures. In fact, current systems deployments are aggregating a significant number of cores interconnected via advanced networking hardware with Remote Direct Memory Access (RDMA) mechanisms, that enable zero-copy and kernel-bypass features. The use of Java for parallel programming is becoming more promising thanks to some useful characteristics of this language, particularly its built-in multithreading support, portability, easy-to-learn properties, and high productivity, along with the continuous increase in the performance of the Java virtual machine. However, current parallel Java applications generally suffer from inefficient communication middleware, mainly based on protocols with high communication overhead that do not take full advantage of RDMA-enabled networks. This paper presents efficient low-level Java communication devices that overcome these constraints by fully exploiting the underlying RDMA hardware, providing low-latency and high-bandwidth communications for parallel Java applications. The performance evaluation conducted on representative RDMA networks and parallel systems has shown significant point-to-point performance increases compared with previous Java communication middleware, allowing to obtain up to 40% improvement in application-level performance on 4096 cores of a Cray XE6 supercomputer.
