Enabling financial service firms to compute heterogeneously with Gateware Defined Networking (GDN) to build order books and trade with the lowest latency.


Abstract and Objectives

Stock, futures, and option exchanges; market makers; hedge funds; and traders require real-time  knowledge of the best bid and ask prices for the instruments that they trade. By monitoring live market data feeds and computing an order book with Field Programmable Gate Array (FPGA) logic, these firms can track the balance of pending orders for equities, futures, and options with sub-microsecond latency. Tracking the open orders by all participants ensures that the market is fair, liquidity is made available, trades are profitable, and jitter is avoided during bursts of market activity.

Algo-Logic has developed multiple Gateware Defined Networking (GDN) algorithms and components to support ultra-low-latency processing functions in heterogeneous computing systems. In this work, we demonstrate an ultralow latency order book that runs in FPGA logic in an IBM POWER8 server, which includes an ultra-low-latency 10 Gigabit/second Ethernet MAC, a market data feed handler, a fast key/value store for tracking level 3 orders, logic to sort orders, and a standard PSL interface which transfers level 2 market snapshots for multiple trading instruments into shared memory. Algo-Logic implemented all of these algorithms and components in logic on an Altera Stratix V A7 FPGA on a Nallatech CORSA card. Sorted L2 books are transferred over the IBM CAPI bus into cache lines of system memory. By implementing the entire feed processing module and order book in logic, the system enables software on the POWER8 server to directly receive market data snapshots with the least possible theoretical latency and jitter.

As a member of the Open Power Foundation (OPF), Algo-Logic provides an open Application Programming Interface (API) that allows traders to select which instruments they wish to track and how often they want snapshots to be transferred to memory. These commands, in turn, are transferred across the IBM-provided Power Service Layer (PSL) to the algorithms that run in logic on the FPGA. Thereafter, trading algorithms running in software on any of the 96 hyper-threads in a two-socket POWER8 server can readily access the market data directly from shared memory. When combined with a Graphics Processing Unit, a dual-socket POWER8 system optimally leverages the fastest computation from up to 96 CPU threads, high-throughput vector processing from hundreds of GPU cores, and the ultra-low latency from thousands of fine-grain state machines in FPGA logic to implement a truly heterogeneous solution that achieves better performance than could be achieved with homogeneous computation running only in software.
