Triton Resource - Hardware Overview

The UCSD Triton Resource at SDSC is a new high-performance, data-centric compute resource for UCSD faculty research, that is also available to other UC campuses and to governmental, educational, and private industry. The resource features exceptional data analysis capabilities and short wait times at extremely reasonable cost to users.

The resource comprises three major components: a Petascale Data Analysis Facility, a 256-node Compute Cluster, and a Data Oasis. Each offers unique and powerful capabilities designed to support data analysis needs on scale with today's most demanding and data-intensive processing tasks. The multiprotocol Myrinet switch enables Triton Resource high-speed fabric connections to multiple 10-gigabit ethernet networks, including the OptIPuter/Quartzite Research Network, the UCSD Campus Research Network, and the UCSD production network.

The system fabric is supplied by a Myricom Myrinet Multiprotocol Switch with 448 MX ports, 32 ten-gigabit ethernet ports and 32 expansion ports. This gives the resource an approximate worst-case MPI latency of 2.4 microseconds and an achievable 1.2 gigabytes per second per network interconnection.

The Myrinet fabric is a full-bisection Clos-topology two-level network. As configured, the bisection bandwidth of the switch exceeds 500 gigabytes per second (four terabits per second).

The PDAF and Triton Compute Cluster are connected to each other at full-bisection.
