Tested POSIX compliance using the POSIX Filesystem Test Suite —Passed 1951/1957 tests; failed 6/1957 —Most UNIX systems aren’t 100% POSIX compliant Tested read/write speeds using IOR Tested file creation/deletion speeds with mdtest Benchmarking & Results

UnifyFS is a temporary, virtual file system on the compute node, which means data has less distance to travel and circumvents POSIX obstacles while the application runs. It also eliminates the need for time-consuming development to optimize every application for better I/O performance; UnifyFS itself is the optimization.

•We have a memory “helper” API to access application memory pools – solver libraries could benefit from exploiting this too SUNDIALS keeps state data on the GPU Application / discretization framework: RHS Function, f RHS Jacobian, J f Preconditioner, P Linear solver Time integrator Nonlinear solver z x z0, F, J F Ax m, P-1r Application ...

Application Programming Interface (API) and its implemen-tation to support the file access and information needs of a wide range of HPC programs, libraries and tools. This paper makes the following contributions: A novel node-local technique to raise locally-defined file names to a global namespace;

2025年3月4日 · These backends are written using a shared API, so that simple codes written and tested on laptops can run on enormous problems on HPC systems with little or no change to the source code. Additionally, MuyGPyS empirically optimizes using much less time, energy, and specialized equipment than state-of-the-art neural architectures like LLMs, which ...

For computational mathematician Julian Andrej, working at Lawrence Livermore was serendipitous. Andrej joined LLNL’s Center for Applied Scientific Computing in 2019 as a postdoctoral researcher after completing his Electrical Engineering degree at …

2024年6月25日 · Finally, for flexible and portable tuning on different computing systems, UMap provides both API and environmental controls to enable configurable page sizes, eviction strategy, application-specific prefetching, and detailed diagnosis information to the programmer.

•Process: Pull data from the REST API and insert it into the HTML document —Graphical Display •Process: Pull data from the REST API, extract and separate keys and values, insert data into Plotly graphs Accurately update data on initial load and when the date range is modified

In the SCR-CRUISE case, checkpoints are directed to CRUISE. All application I/O operations are intercepted by the CRUISE library. File names prefixed with a special mount name are processed by CRUISE, while operations for other file …

However, few of the API changes, other than to the cfp C API for compressed arrays, should impact existing code. Note that numerous header files have been renamed or moved relative to prior versions. Added. zfp::const_array: read-only variable-rate array that supports fixed-precision, fixed-accuracy, and reversible modes.
