Benchmarks: Haswell vs. Ivy Bridge for Financial Analytics

Intel just released its new Haswell server processor line (Xeon E5 v3 series), promising significant performance gains over previous-generation Ivy-Bridge processors. In this post, we will compare the two generations for a popular financial application – a Monte-Carlo LIBOR Swaption Porfolio pricer.

White Paper: RTM – Design for Performance and Flexibility

We’ve just published a new white paper which looks at how to boost Reverse Time Migration algorithms while maintaining flexibility and portability. This white paper features an implementation that achieves up to 9,000 MCells/s on a single K40 GPU (8th order in space, 2nd order in time, 3D isotropic).

This white paper shows how to develop high performance Reverse Time Migration (RTM) implementations that are both flexible and easy to maintain, by using the Xcelerit platform. As energy exploration is pushed towards more complex geologies, RTM has become the de-facto standard algorithm to construct images of the Earth’s subsurface from measured seismic wave data. High performance hardware such as GPUs allow to cope with the tremendous computational complexities involved – at the cost of increased software development and maintenance effort.

Xcelerit Keeps Delegates Alert at Global Derivatives, Amsterdam

Xcelerit were represented at last month’s Global Derivatives conference in Amsterdam’s Okura Hotel. This is the largest annual gathering in Quantitative Finance

We found the latest advances for reducing the complexity of xVA calculations particularly exciting. For example, Jesper Andreasen (Dankse Bank) presented a number of smart algorithmic optimisations for xVA, Adil Reghai (Natixis) showed how to use algorithmic differentiation cleverly to reduce CVA complexity, and Andrew Green (Lloyds Banking Group) presented a highly efficient method to compute FVA of VAR-based inital margin. Additionally, for the first time this year, the conference featured a stream about “Innovations in Computational & Numerical Efficiency,” with a number of implementation-centric talks on how to cope with the computational complexities of financial analytics.

The audience of more than 500 quants were revived at break time by Xcelerit’s crack team of baristas, who sent them back to the following sessions freshly caffeinated and ready to absorb more.

London gets ready for the New Normal : Risk Aware OTC-Pricing Seminar Hits the Spot

On May 28th, Xcelerit in association with the Wilmott Forum delivered a seminar on “xVA and Risk-Aware OTC Pricing: Getting Ready for the New Normal” to an audience of quantitative analysts and other financial industry specialists in London.

The risk trainer Justin Clarke started by explaining the forces driving the drastic changes facing banks’ risk departments and trading desks. He illustrated the complexities involved in computing the multitude of adjustments to OTC prices required for compensating the associated risks (xVA). His talk was followed by a session with Xcelerit’s CEO, Hicham Lahlou, who demonstrated how the calculations needed can be achieved within the turnaround times required, using Xcelerit’s tools. Xcelerit’s Jorg Lotze, concluded the seminar with a live demonstration, showing the audience the achievable performance on GPUs without requiring major modifications to the existing codebase.

The event was over-subscribed and even though we maintained a waiting list, many people were still left disappointed. We are happy to announce that a video of the event is now being made available on our website. If you missed it, click here to gain access to the material.

White Paper: xVA – Coping with the Tsunami of Compute Load

We’ve just published a new white paper which covers how to cope with the computational complexity involved in calculating various valuation adjustments, such as Credit Valuation Adjustment (CVA), Debit Valuation Adjustment (DVA), and Funding Valuation Adjustment (FVA).

These adjustments are commonly referred to as xVA. This white paper gives an overview of the different xVA adjustments, shows
how they are typically computed, and outlines where the computational complexities lie. We give recommendations on how to achieve high performance, portability, and scalability for centralised in-house xVA implementations. We show how, by careful software design, we can easily harness, not only the power of multi-core CPUs, but also accelerator co-processors such as graphic processing units (GPUs) and the Intel Xeon Phi.

Xcelerit goes to College

Oxford University

Last month, Xcelerit presented at the UK Many-Core Developer conference in Oxford, UK. The conference was held in the new Andrew Wiles building, named after Oxford’s distinguished mathematician who is most famous for proving Fermat’s last theorem. It’s goal was to strengthen the UK’s expertise in many core computing and Xcelerit CTO, Jorg Lotze, was part of an accomplished panel of speakers from Oxford, Imperial College, London and Bath Universities. Industry was also well represented, with speakers from innovative hardware manufacturers like ARM featured alongside niche specialist like Ridgeway Kite Software.

Benchmarks: NVIDIA Tesla K40 vs. K20X GPU

NVIDIA freshly released their new flagship Tesla GPU, the Tesla K40. This GPU features more memory, higher clock rates, and more CUDA cores than the previous top-end card, the K20X. But what performance improvements can we expect for financial applications? We’ve put the new card to the test and compared it to the K20X using a Monte-Carlo LIBOR swaption portfolio pricer, a real-world financial algorithm that we’ve already used in other benchmarks.

Back from the Fixed Income Conference in Munich

Xcelerit were represented at last week’s Fixed Income Conference in Munich’s Sofitel Bayerpost. We had a busy display stand in the hotel concourse and our CTO Jorg Lotze gave a presentation revealing some of our CVA implementation secrets. This session was very well attended despite the late dinner at the Augustiner Keller on the evening before.
