Dear IOR and mdtest users and contributors, The IOR benchmark has recently seen a revival of development with some substantial new features being contributed by members of the community. At present, the most feature-rich and actively maintained fork of the original IOR is at https://github.com/ior-lanl/ior, but the breadth of the community participating in that fork has grown beyond its original maintainers at Los Alamos National Laboratory. In response to this evolution, the current maintainers of IOR-LANL would like to move the IOR benchmark, including the mdtest benchmark that was recently merged into this fork, into an institution-neutral location. Therefore, we are planning to relocate the official IOR/mdtest to https://github.com/hpc, which is a GitHub organization with representatives from academia, government, and industry. Following this relocation, we will begin laying out a roadmap for IOR/mdtest feature development with the involvement of any and all interested members of the IOR/mdtest community. Before we relocate IOR/mdtest and begin feature planning, though, we would like feedback from IOR/mdtest users and contributors to gauge community interest and address any questions or concerns. Barring any major objections, we plan to move IOR/mdtest, archive the LANL fork, and begin roadmap planning in January 2018. Sincerely, The IOR maintainer team
