Cirrascale RM4950 POWER8® Development Server

Based on the IBM® POWER8® 4-core Turismo SCM processor, and designed with NVIDIA® Tesla® GPU accelerators in mind. The new Cirrascale RM4950 is a POWER8-based development system that provides a solution perfectly aligned to support GPU-accelerated big data analytics, deep learning, and scientific high-performance computing (HPC) applications.

Product Features and Benefits

  • OpenPOWER customer reference system perfect for evaluating POWER8 performance.
  • Delivers the capability to support up to four of the latest NVIDIA Tesla GPU Accelerators with ease.
  • Supports the Cirrascale SR3514 PCIe switch riser enabling up to four PCIe devices on a single root complex.
  • Tailored for the surging growth of big data, machine and deep learning applications.

Cirrascale RM4950 Development Server Overview

The Cirrascale RM4950 POWER8-based Development Platform is a customer reference system which allows customers to deploy software based on the OpenPOWER architecture and evaluating performance and energy efficiency use in standard workloads. The RM4950 Development Platform provides the capability to support up to four NVIDIA® Tesla® GPU Accelerators for those interested in multi-GPU development capabilities.

The POWER8 is designed to be a massively multithreaded chip, with each of its cores capable of handling eight hardware threads simultaneously, for a total of 24 threads executed simultaneously on the 4-core Turismo chip, and up to 96 threads on the production 12-core processor due out later this year. The processor makes use of very large amounts of on- and off-chip eDRAM caches, and on-chip memory controllers enabling very high bandwidth to memory and system I/O. For most workloads, the chip is said to perform two to three times as fast as its predecessor (POWER7).

The Cirrascale RM4950 enables best-in-class performance per watt and performance per dollar. Coupled with NVIDIA Tesla GPU Accelerators, this platform is ideally suited for High Performance Computing environments utilizing highly parallel, high throughput applications and delivers industry's leading performance per watt.

Additionally, the NVIDIA Tesla family is built on the NVIDIA Kepler™ compute architecture and powered by NVIDIA CUDA®, the world's most pervasive parallel computing model. This makes them ideal for delivering record acceleration and more efficient compute performance for big data applications in fields including seismic processing; computational biology and chemistry; weather and climate modeling; image, video and signal processing; computational finance, computational physics; CAE and CFD; and data analytics.

PLEASE NOTE: The Cirrascale RM4950 Development Platform is an OpenPOWER development reference platform intended for the sole purpose of early experimentation and product or code development on the OpenPOWER architecture and therefore it is not intended for a production environment. Not all functions have been rigorously tested and new features or functions may become available in the future.
