Access "Firm Eliminates Hassles of Clustered Apps"

Published: 17 Oct 2012

The lure of cheap Linux clusters is getting stronger. According to Steve Feldman, director of software development at CD Adapco, which makes software to calculate computational fluid dynamics (CFD), "every day we get a call from someone about Linux clusters." That's because a Linux cluster made up of inexpensive one- or two-way Intel blades costs a fraction of a single equivalent large RISC-based symmetric multiprocessing (SMP) server. But without a clustered file system to provide a single data store to each of the parallel blades, management of the cluster is a real headache, Feldman says. To that end, CD Adapco has deployed its software on a Fujitsu's hpcLine of Intel-based servers running Sistina Software's Global File System (GFS) a clustered file system. Without a clustered file system providing centralized disk management, each CFD "run" requires that the full dataset be copied to a local disk associated with each processor in the cluster. Then after the run is completed, results are merged and copied to a central location. By implementing GFS, ... Access >>>
