Using existing TCP/IP emulation layers over InfiniBand networks in Java applications presented rather poor communication performance and heavy overhead in host CPU. In this paper, we propose Jdib (Java Direct InfiniBand), a Java application acceleration technique to directly exploit RDMA (Remote-Direct-Memory-Access) capability of In-finiBand network hardware. The preliminary test results show that with Jdib API, micro-benchmark written by Java can achieve latency performance (~9us) comparable
more » ... ith that of micro-benchmarks written by C language (~8.5us) in 20Gbps InfiniBand fabrics.
