This respository contains a number of benchmarks we have created to evaluate the performance of non-volatile memory, NVMe hardware, pmem.io, and other aspects of the hardware we will use to build the NEXTGenIO prototype.
We are interested in evaluating both hardware performance, and software overheads, and therefore have benchmarks that are purely hardware focussed, and benchmarks that investigate the software performance aspects of I/O and memory movements.
The ngio-kernel-benchmarks directory contains level1 kernel benchmarks (build on ones originally developed for the Adept project (https://github.com/EPCCed/adept-kernel-openmp)). Of particular interest for I/O is the file parse benchmark, which does file operations either using linux posix functionality or the pmem.io library.
The ngio-micro-benchmarks directory contains level0 micro benchmarks (build on ones originally developed for the Adept project (https://github.com/EPCCed/adept-micro-openmp)). Of particular interest for I/O are the file benchmarks, which evaluate the costs of file open and writing/reading in various different modes, using linux posix functionality or the pmem.io library.
The memory benchmarks have also been extended to use the vmem functionality from pmem.io to use memory on a non-volatile device rather than standard main memory.
