Computational finance is central to modern financial markets, and an area in which there is a significant amount of commercial and academic interest. To date, grid computing techniques have been applied to this domain.
Subject : Adequation of grid computing to computation intensive calculations in the financial domain
Financial applications require to solve large size computations, that are so huge that they can not be tackled by conventional PCs. A typical example addresses risk analysis evaluation as periodically run by financial institutions (like VaR -- Value at Risk --, and also market risks: greeks, duration, beta, ...). Such risks apply to large sets of financial products (all that are owned or managed by the financial institution), which are very heterogeneous (auctions, contracts, loans, options, etc), and highly parameterized (such as the maturity for options and loans for instance). Moreover, risks depend on external economical factors (as interest rate shocks, currency exchange rates, auctions in specific industrial areas, etc). The use of parallelism is of now and already applied in this financial context, but its usage in Grids is far from being mastered.
PhD Subject
The aim of this PhD research work is to highlight the potential of parallel techniques applied to mathematical finance computing on Grid infrastructures. This should lead to drastic improvements of the risk evaluations at an industrial scale. In order to prove this, the research will specifically focus on computations of volatility and quantiles using Monte Carlo simulation standard techniques, and related more recent techniques for variance calculation or adaptative Monte Carlo simulations (that require much more communications on the Grid than standard Monte Carlo ones). Computing grids are foreseen as a relevant technical solution for computation intensive risk evaluations. But, this requires a mixed approach, adding to classical parallel implementations adequate fault-resilience solutions. The parallelisation of risk evaluation yields a -- possibly quite large -- decomposition into tasks, that subsequently need performant access means to financial databases and dataflows used in those financial calculations. Moreover, those tasks, deployed and running on the Grid, may be demanding regarding synchronization and communication. So, designing a grid-based software platform, able to run financial risk evaluations is really a challenge, that this Doctoral research work's objective is intended to address.
The results of this research will be able to be immediatly given industrial value. Indeed, this research work is lean against a research contract funded by the French Research Agency (ANR), in the Computing Intensive and Grid Computing areas, named GCPMF (Grilles de Calcul appliquées aux Mathématiques Financières). The consortium that conducts this project includes financial institutions and software providers for such institutions. They should be the first to experiment and eventually adopt and apply those research results.
Profile of the candidate
The candidate should be skilled both in mathematical finance, and in computer science (algorithmics, object-oriented programming, distributed software, databases, parallelism and distribution).
