Programmed Logic Corp. Announces File System Optimized for High Performance Computing.
HPC Access Method Efficiently Handles Terabyte Files
Programmed Logic Corp. announced at SC98 today new HPC Access Method (AM) technology. HPC Access Method extends Programmed Logic's HTFS (High Throughput File System) software to provide a full 64-bit system capable of optimizing throughput for gigabyte, and even terabyte-sized files.
HPC AM streamlines HPC applications such as scientific, video, medical imaging, seismic, and energy management, by eliminating "metadata bottleneck": user data within large files are stored separately from it's metadata and other small, frequently accessed system files. Then, the most efficient access method is automatically applied according to the type of data. Conventional file systems store both types of data on the same device, leading to conflicts and bottlenecks due to read/write contention between user and system files.
Typically, the device that stores the application data is a collection of high speed disks and controllers configured as a RAID (redundant array of inexpensive disks) device. HPC AM further maximizes throughput by matching user data block sizes to the dimension of a RAID 5 stripe array, guaranteeing alignment and enhancing RAID 5 performance.
HTFS is Programmed Logic's transaction-oriented, high availability file system implemented by Unix OEM customers since 1992. The new development brings the advantages of HTFS to the HPC arena. These include a modular framework that allows developers to tailor the file system to the specific requirements of an application, and a journaling architecture that facilitates rapid system recovery. In addition to the HPC Access Method, HTFS supports streamed I/O, compressed and record I/O access methods, all accessible within a single file system configuration.
HTFS with the HPC Access Method is available on popular hardware configurations running Programmed Logic's StackOS storage-centric operating system.and on Unix Solaris environments. StackOS can be easily integrated with RAID subsystems running a real-time operating system (RTOS).
