Ndivia ja Espanja suunnittelevat Arm pohjaista superia

The Barcelona Supercomputing Center (BSC) has announced it will develop a hybrid supercomputer based on Nvidia Corp.'s Tegra ARM CPUs and the firm's CUDA-supporting Tesla GPUs, with hopes of reaching exascale performance.

C believes its prototype system will be the world's first ARM-based CPU/GPU supercomputing combination. The center says it is aiming for a two to five times improvement in energy efficiency compared to today's most efficient systems in the short term, with the ultimate goal of reaching exascale using 15 to 30 times less power than current supercomputer architectures.

Energiatehokkuus on tärkeää supertietokoneissa.

Markkinoiden siirtyminen Armin suuntaan ja eksoottisiin arkkitehtuureihin on Linuxille suhteellisesti paljon edullisempaa kuin Microsoftille.
