At SC17 in Denver, the Japanese RIKEN K computer emerged for the third straight time as the world’s most powerful supercomputer based on the High Performance Conjugate Gradient (HPCG) benchmark list. Although China’s Tianhe-2 supercomputer has been widely seen as number one in the world based on its LINPAC rating, the HPCG test that the K computer excelled on may be more representative of the range of real-world HPC problems encounter by users. Riken’s K computer has been either number one or two since the HPCG list came out in 2014.
IBM's recent announcement of their new Q System One universal quantum computer is yet another milestone in the firm's long-term commitment to transitioning quantum computing (QC) hardware from one-off research status into a capable commercial offering. Although the new Q System One, as announced, does not demonstrate any significant advances in current quantum computing capability, as measured by the number of qubits per system, it does show that IBM can design and manufacture a system that, at the right price, could be attractive to a wide range of users looking to integrate quantum computing into their overall R&D process.

This Quick Take looks at Amazon's recent announcement of a new EC2 Bare Metal offering that provides users with direct, non-virtualized access to a processor, memory, storage and related networking instance. Amazon uses custom hardware in an effort to wring out the highest possible performance from the basic hardware set up while still offering a full complement of cloud-based software support. This development is a positive one for HPC users looking to migrate workloads to public clouds as Amazon is addressing one of the most vexinghurdles of HPC in the cloud: the performance overhead of running applicationsin a virtualized, performance limiting environment.
