Peter A. Forsyth

Professor, BSc (Western Ontario 1975), MSc (Australian National 1977), PhD (Western Ontario 1979)

Personal History

After graduating in 1979, Peter was a Senior Simulation Scientist at the Computer Modelling Group (CMG) in Calgary, where he developed petroleum reservoir analytics. After leaving CMG, Peter was the founding President of software startup Dynamic Reservoir Systems (DRS), also in Calgary. DRS produced reservoir simulation software for desktop workstations, using the then enormous amount of RAM memory available (640K). DRS had three employees: a president and two vice-presidents. After selling out his shares in DRS (now owned by Duke ) in 1987, Peter joined the University of Waterloo, where he was a Professor in the Cheriton School of Computer Science. After 29 years, Peter officially retired from Waterloo on November 1, 2016, and is now a Professor Emeritus. Life continues on pretty much as before, except that now he does not have the joy of attending committee meetings, which is one of the highlights of being a professor.

Peter's current research focuses on Computational Finance. He is a member of the Editorial Board of Applied Mathematical Finance and the Journal of Computational Finance. During the years 2008-2013, he was the Editor-in-chief of the Journal of Computational Finance.

In recent years, Peter has also carried out research related consulting for such organizations as: SunLife of Canada, NOVA, the Electric Power Research Institute, Smithville Bedrock Remediation Corporation, Los Alamos National Laboratory, Oak Ridge National Laboratory, and HydroGeoLogic.

Peter's research has been funded by such organizations as: Neuberger Berman, the Royal Bank of Canada, Scotiabank, Credit Suisse, Tata Consultancy Services, Morgan Stanley, ITO33, Bell Canada, and the Global Risk Institute.

While at Waterloo, Peter has held such administrative positions as: Associate Chair Graduate Studies (1991-1993), Director of the Institute for Computer Research (1995-1998), Associate (Vice) Director of the Cheriton School of Computer Science (2002-2005), Scientific Director of the Institute for Quantitative Finance and Insurance (2006-2008), and Director (Infrastructure), Cheriton School of Computer Science (2009-11).

Peter is currently a director of Aquanty, a software startup specializing in integrated modelling of three dimensional surface/subsurface water flows. Aquanty specializes in simulating the impact of industrial activity and climate change on water resources.

Peter left CMG (the Computer Modelling Group) in 1985. About 25 years ago, shares of CMG were trading at about $0.05 (split adjusted). Look at the CMG share price. Peter thinks about this every day.

Charles Dickens had it right

"You surprise me. That's singular, sir. I have generally found, in my experience, that it's their own money people are most particular about. I have seen people get rid of a good deal of other people's money, and bear it very well: very well indeed." From Little Dorrit, Charles Dickens

Courses Taught

Undergraduate courses: introduction to scientific computing, numerical linear algebra, numeric computation for dynamical simulation, software system design and implementation. Graduate courses: numerical solution of partial differential equations, preconditioners for sparse matrices, numerical solution of nonlinear hyperbolic partial differential equations, computational finance.

C++ Iterative Sparse Matrix Solver

I have a C++ version of the Watsit sparse matrix solver package (scaler only for now). The solver is based on a PCG-like method which uses an incomplete LU factorization preconditioner. Level or drop tolerance preconditioning can be specified. This package has been successfully tested on problems in CFD, 3-D linear elasticity, option pricing, semi-conductor device simulation, and multi-phase subsurface flow. You can download the pdf user manual.
