Adapting Remote Direct Memory Access Based File System to Parallel Input-/Output

Traditional file access interfaces rely on ubiquitous transports that impose severe restrictions on performance and prove insufficient for adaptation to parallel Input/Output (I/O). Remote Direct Memory Access based (RDMA-based) approaches are aimed at moving data between different process address spaces with streamlined mediation and reduced involvement of the operating system using synchronization semantics that are different from ubiquitous transports. This thesis studies the adaptability of RDMA-based transports to parallel I/O. Combining RDMA semantics with parallel I/O leads to overhead reduction by overlapping communication and computation and by bandwidth enhancement. Although parallel I/O tends to increase latency in certain cases, use of RDMA techniques mitigate on this effect
