Sign in to saveAlso known as GPFS
GPFS (General Parallel File System, brand name IBM Storage Scale and previously IBM Spectrum Scale) is a high-performance clustered file system software developed by IBM. It can be deployed in shared-disk or shared-nothing distributed parallel modes, or a combination of these. It is used by many of the world's largest commercial companies, as well as some of the supercomputers on the Top 500 List. For example, it is the filesystem of the Summit at Oak Ridge National Laboratory which was the #1 fastest supercomputer in the world in the November 2019 Top 500 List. Summit is a 200 Petaflops syst

at Oak Ridge National Laboratory which was the #1 fastest supercomputer in the world in the November 2019 Top 500 List. Summit is a 200 Petaflops system composed of more than 9,000 POWER9 processors and 27,000 NVIDIA Volta GPUs. The storage filesystem is called Alpine.
