Abstract
Modern cluster environments' main trouble used to be lack of computational power provided by CPUs and GPUs, but recently they suffer more and more from insufficient performance of input and output operations. Apart from better network infrastructure and more sophisticated processing algorithms, a lot of solutions base on emerging memory technologies. This paper presents evaluation of using non-volatile random-access memory as a main storage of Parallel File System. The author justifies feasibility of such configuration and evaluates it with MPI I/O, OrangeFS as a file system, two popular cluster I/O benchmarks and software memory simulation. Obtained results suggest, that with Parallel File System highly optimized for block devices, small differences in access time and memory bandwidth does not influence system performance.
