Tech: Gordon: Design, Performance, and Experiences

    Tech: Gordon: Design, Performance, and Experiences Deploying and Supporting a Data-Intensive Supercomputer

    Abstract: The Gordon data intensive supercomputer entered service in early 2012 as an allocable computing system in the NSF 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 space. In this paper we present the motivation, design, and performance of Gordon. We provide: low level micro-benchmark results to demonstrate processor, memory, I/O, and network performance; standard HPC benchmarks; and performance on data intensive applications to demonstrate Gordon’s performance on typical workloads. We highlight the inherent risks in, and offer mitigation strategies for, deploying a data intensive supercomputer like Gordon which embodies significant innovative technologies. Finally we present our experiences thus far in supporting users and managing a system like Gordon.
