The Oak Ridge Leadership Computing Facility (OLCF) has deployed multiple large-scale parallel file systems (PFS) to support its operations. During this process, OLCF acquired significant expertise in large-scale storage system design, file system software development, technology evaluation, benchmarking, procurement, deployment, and operational practices.(More)
Increase in graphics hardware performance and improvements in programmability has enabled GPUs to evolve from a graphics-specific accelerator to a general-purpose computing device. Titan, the world's second fastest supercomputer for open science in 2014, consists of more than 18,000 GPUs that scientists from various domains such as astrophysics, fusion,(More)
Balancing the use of FGPA resources such as FPGA slices, block RAMs, and block multipliers is desirable in many FPGA applications. This task can be carried out manually by experienced hardware designers with the use of hardware description languages, such as Verilog and VHDL. However, many users of reconfigurable computers are software developers who depend(More)
and turn it into something useful for scientists was always an interesting challenge for me. " Bland thinks very highly of the formative years he spent in service. It was during his final year in the Air Force that he taught the Ada programming language, an experience that contributed to him developing soft skills, before finally coming to oak Ridge to(More)
