EMC and Los Alamos National Security Assigned Patent

EMC Corporation, Hopkinton, MA, and Los Alamos National Security, LLC, Los Alamos, NM, has been assigned a patent (9,286,261) developed by Tzelnic, Percy, Concord, MA, Faibish, Sorin, Newton, MA, Gupta, Uday K., Westford, MA, Bent, John, Grider, Gary Alan, and Chen, Hsing-bung, Los Alamos, NM, for a “architecture and method for a burst buffer using flash technology.”

The abstract of the patent published by the U.S. Patent and Trademark Office states: ”A parallel supercomputing cluster includes compute nodes interconnected in a mesh of data links for executing an MPI job, and solid-state storage nodes each linked to a respective group of the compute nodes for receiving checkpoint data from the respective compute nodes, and magnetic disk storage linked to each of the solid-state storage nodes for asynchronous migration of the checkpoint data from the solid-state storage nodes to the magnetic disk storage. Each solid-state storage node presents a file system interface to the MPI job, and multiple MPI processes of the MPI job write the checkpoint data to a shared file in the solid-state storage in a strided fashion, and the solid-state storage node asynchronously migrates the checkpoint data from the shared file in the solid-state storage to the magnetic disk storage and writes the checkpoint data to the magnetic disk storage in a sequential fashion.“

The patent application was filed on November 13, 2012 (13/676,000).
