IBM Built Three of the Top 11 Supercomputers in the World Today

IBM is the only vendor to have multiple systems in the Top 10 of the semi-annual Top500 and Green500 supercomputer lists. This includes the US Dept of Energy’s Summit and Sierra supercomputers, the overall number one and number two most powerful supercomputers in the world, along with the Lassen Supercomputer built for Lawrence Livermore National Labs. IBM also teamed with a global oil producer for the world’s most powerful commercial supercomputer that debuted on the Top500 list at #11″

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.
