Seminar, Department of Computer Science

Seminar 1: Java in the real world

1:00 - 2:00 pm

Paul Murray
Goldman Sachs


The modern enterprise development environment is an exciting place. The ability to exploit innovation in hardware and software is a critical differentiator for commercial success. This talk will discuss some of the core technologies that Goldman Sachs is currently using to build java applications. It will focus particularly on the ways in which the firm is taking these technologies to the limits of their capabilities and how it works with vendors and the open-source community to ensure stability and scalability.
The talk will also discuss some of the skills that the next generation of enterprise-development practitioners will need in order to build applications that can scale to meet the ever-growing demands of the business.


Paul Murray is a Technology Fellow at Goldman Sachs. His primary areas of research are in application stability, performance and scalability. Paul's team acts as the firm's authority on fundamental aspects of java - such as the virtual machine and the java language - and they provide consultancy and support to the entire Goldman Sachs developer community. Paul has been with Goldman Sachs for seven years. He previously worked in the field of dynamic compiler technologies, spending for four years in the compiler group at Silicon Graphics, where he specialized in JIT compiler design. Paul also spent seven years at Insignia Solutions where he was responsible for the design and implementation of the JIT-based CPU emulation technology used in their flagship "SoftPC" product.

Seminar 2: How to design networks for low latency trading applications

2:00 - 3:00 pm

Matthew Liste
Goldman Sachs


Nowadays, the vast majority of trades are being executed electronically, and human traders are increasingly being replaced by computers pre-programmed to trade accordingly to complex mathematical and statistical algorithms. These systems are able to calculate a multitude of variables and execute thousands of trades in a split-second. They make their money by placing their order before the competition, thus every microsecond counts.
This talk will discuss briefly how trading by computers, known as program trading, works. We will then delve into a discussion of how the underlying networks are built to facilitate this trading, where the sources of latency lie, how we can measure it, and some of the approaches we can take to minimize latency. We will discuss the various network components and common architectures of those to understand how we can better design networks to offer low latency for use in trading environments.


Matthew Liste is a Vice President with Goldman Sachs, where he manages the Network Architecture team. Matthew has more than seventeen years of experience in networking, and possesses a strong understanding of network architectures for both enterprise and service provider environments. Prior to joining Goldman Sachs in 2004, Matthew consulted on leading-edge network technologies at financial services companies such as UBS, Deutsche Bank and JPMorganChase. Before that, Matthew worked at Schlumberger and Nortel Networks, where he received two patents on network management systems. In addition to his work at Goldman Sachs, Matthew currently sits on the board of Nethope, a nonprofit IT consortium of leading international NGOs focusing on connectivity, and has chaired the program committee chair for the infrastructure conference at Interop, the premiere global networking conference, Matthew received his Bachelors of Science degree from University of Oslo in 1990.
