SGI® UV2: a fused computation and data analysis machine

Abstract

Translate Article

UV2 is SGI's second generation data fusion system. UV2 was designed to meet the latest challenges facing users in computation and data analysis. Its unique ability to perform both functions on a single platform enables efficient, easy to manage workflows. This platform has a hybrid infrastructure, leveraging the latest Intel® EP processors providing industry leading computational power. Due to its high bandwidth, extremely low latency NUMALink®6 (NL6) interconnect, plus vectorized synchronization and data movement, UV2 provides industry leading data intensive capability. It supports a single operating system (OS) image up to 64TB and 4K threads. Multiple OS images can be deployed on a single NL6 fabric, which has a single flat address space up to 8PB and 256K threads. These capabilities allow for extreme performance on a broad range of programming models and languages including OpenMP[1], MPI, UPC[2], CAF[3] and SHMEM. The architecture, implementation and performance of UV2 are detailed.
