Pierre Jolivet


I am a research scientist at CNRS. The Toulouse Institute of Computer Science Research (IRIT) is my host laboratory.
I work in the field of high-performance computing (especially for the design of fast and robust solvers in computational sciences).

Here is a list of software that I am developing:
I also (seldom) contribute to:
