IBM Highlights from this iteration of the TOP500 list and Green500 list, rank systems by performance and energy efficiency, respectfully include:
"IBM was an early-adopter of data-centric design principles, and when we began developing POWER9 for the HPC industry we maintained that we wanted it to be measured by application performance", stated IBM Vice President of Exascale Systems David Turek. "Our systems appearing in the top ranks for both performance and energy efficiency is a testament to our efforts. Also, seeing this technology now permeate into commercial systems is an important development for the industry as we evolve these workloads for both traditional and deep learning applications."
IBM POWER9's industry leading approach to memory bandwidth allows for 9,5x faster data transfer between the POWER9 processor and its attached accelerators vs compared x86. IBM POWER9 systems are designed to move data throughout the system with fewer bottlenecks and improve energy efficiency.
As part of the OpenPOWER Foundation, IBM worked with NVIDIA to jointly develop the industry's only CPU-to-GPU NVIDIA NVLink connection, which allows for 5,6x faster memory bandwidth between the IBM POWER9 CPU and NVIDIA Tesla V100 Tensorcore GPUs than compared x86-based systems. This allows for nearly a 4x reduction in AI model training versus the compared x86 based systems.
New on the TOP500 list is Pangea III, a new supercomputer built by IBM for Total. Pangea III is being built using the same IBM POWER9, high-performance architecture as used in the U.S. Department of Energy's Summit and Sierra supercomputers, the world's smartest supercomputers. IBM POWER9 is designed to take advantage of attached accelerators, which can help clients not only improve performance but also improve energy efficiency in their HPC workloads.
