Abstract: SDSC's Gordon system entered service in early 2012 as an allocable system in the NSF's Extreme Science and Engineering Discovery Environment (XSEDE) program. Gordon has several innovative features that make it ideal for data intensive computing including: 1,024, dual socket, 16-core, 64GB compute nodes based on Intel's Sandy Bridge processor; 64 I/O nodes with an aggregate of 300 TB of high performance flash (SSD); large, virtual SMP "supernodes" of up to 2 TB DRAM; a dual-rail, QDR InfiniBand, 3D torus network based on commodity hardware and open source software; and a 100 GB/s Lustre-based parallel file system, with over 4 PB of disk. This talk will present the motivation, design, and performance of Gordon including performance on a range of data intensive applications. Inherent risks in, and mitigation strategies for, deploying a data intensive supercomputer like Gordon are also presented, along with experiences thus far in supporting users and managing a system like Gordon.
