DescriptionThe research community in high-performance computing is organized loosely.
There are many distinct resources such as homepages of research groups and benchmarks.
The Virtual Institute for I/O aims to provide a hub for the community and particularly newcomers to find relevant information in many directions.
It hosts the comprehensive data center list (CDCL). Similarly to the top500, it contains information about supercomputers and their storage systems.
I/O benchmarking, particularly, the intercomparison of measured performance between sites is tricky as there are more hardware components involved and configurations to take into account.
Therefore, together with the community, we standardized an HPC I/O benchmark, the IO-500benchmark, for which the first list had been released during supercomputing in Nov. 2017.
Such a benchmark is also useful to assess the impact of system issues like the Meltdown and Spectre* bugs.
This poster introduces the Virtual Institute for I/O, the high-performance storage list and the effort for the IO-500 which are unfunded community projects.
