Scalable Computing on Tianhe-2 System

SESSION: Invited Talks 6

EVENT TYPE: Invited Speakers

TIME: 1:30PM - 2:15PM

SESSION CHAIR: William Tang

Presenter(s):Yutong Lu

ROOM:Mile High

ABSTRACT:
Scalability is one of the big challenges for the post-petascale and exascale systems, we need integrated technologies from architecture design to system software stack design. This talk expresses the efforts from NUDT to design and implement the Tianhe-2 system to get better scalability. From the heterogenous to nero-heterogenous architecture, we got some comparison among cpu, gpu and mic. We design the high bandwidth, low latency communication system with offload collective operations, to improve the scalability of interconnection. We improve the multiple protocols in custom MPI system to support different application models. We design the hybrid hierarchy I/O architecture and file system to tackle the I/O bottleneck. The co-design policy through whole system for scalable computing could support the domain applications extend to even large scale efficiently.
