(~1TB/s) Low time impact on job execution by file IO. File striping will primarily improve performance for codes doing serial I/O from a single node or parallel I/O from multiple nodes writing to a single shared file as with MPI-I/O, parallel HDF5 or parallel NetCDF. Lustre is a high performance scratch system, used for data intensive cluster computing. A Lustre parallel file system achieves its performance by automatically partitioning data into chunks, known as “stripes,” and writing the stripes in round-robin fashion across multiple OSTs. This process, called "striping," can significantly improve file I/O speed by eliminating single-disk bottlenecks. It is the most widely adopted parallel file system in use, powering over 70% of the top 100 supercomputers in the world.
