IBM Cluster systems

Drive performance while reducing energy and space with integrated cluster solutions

System management

Extreme Cloud Administration Toolkit (xCAT) - An open source scalable distributed computing management and provisioning tool that provides a unified interface for hardware control, discovery, and operating system diskful/diskfree deployment. This robust toolkit can be used for the deployment and administration of AIX® or Linux® clusters. Its features are based on user requirements, and take advantage of IBM Power™ Systems and z Systems hardware.

Cluster Systems Management (CSM) - Designed to minimize the cost and complexity of administering IBM clusters built on IBM Power Systems by enabling comprehensive management and monitoring of the entire environment from a single point of control. CSM is supported for existing AIX clusters, but Extreme Cloud Administration Toolkit (xCAT) is now the recommended solution for administration of new cluster deployments.

High performance math libraries

Engineering and Scientific Subroutine Library (ESSL) and Parallel ESSL - Collections of state-of-the-art mathematical subroutines specifically designed to improve the performance of serial, SMP and SPMD applications on the IBM POWER™ processor-based servers. ESSL and Parallel ESSL are commonly used in the aerospace, automotive, electronics, petroleum, utilities and scientific research industries, and support Fortran, C and C++ applications running under AIX and Linux.

ESSL provides Vector Scalar Extension (SIMD) versions of most BLAS and FFT subroutines and is tuned for performance on IBM POWER7 and POWER8 processor-based servers.

Parallel ESSL supports SPMD parallel processing applications on clusters of processor nodes connected by a high speed switch using the Message Passing Interface (MPI) library provided with Parallel Environment Runtime Edition.

Parallel application development and execution

Parallel Environment Runtime Edition and Parallel Environment Developer Edition – Delivers a comprehensive development and execution environment for parallel applications (distributed-memory, message-passing applications running across multiple nodes). Parallel Environment is designed to help engineers develop, test, debug, tune and run high-performance parallel applications in C, C++ and Fortran on IBM Power Systems and IBM System x clusters running on AIX or Linux operating systems.

Job scheduling

LoadLeveler® - Used for dynamic workload scheduling, LoadLeveler is a distributed network-wide job management facility designed to dynamically schedule work to maximize resource utilization and minimize job completion time. Jobs are scheduled based on job priority, job requirements, resource availability and user-defined rules to match processing needs with resources. LoadLeveler provides consolidated accounting and reporting on IBM Power Systems servers, but now IBM Platform LSF is the strategic workload and job scheduling solution.

Parallel file system

General Parallel File System (GPFS) - GPFS™ is a high-performance cluster file management infrastructure for AIX, Linux, Windows® and mixed clusters that provides world-class performance, scalability and availability for your file data. It is designed to optimize the use of storage, to support scale-out applications and to provide a high availability platform for data intensive applications. GPFS provides online storage management, scalable access and tightly integrated information lifecycle tools capable of managing petabytes of data and billions of files. GPFS can help you move beyond simply adding storage to optimizing data management.
