个人简介
My research activity focuses on Computational Linear Algebra. This discipline deals with the issues related to the efficient and numerically reliable computation of linear algebra operations arising in numerous scientific and industrial applications from a wide range of domains including physics, chemistry or data analysis. These applications commonly involve data of very large size, which makes the use of supercomputers unavoidable to cope with the resulting considerable computational and memory cost. As a result, my work is concerned with the development of reliable, efficient and scalable numerical linear algebra methods as well as their implementation on large-scale parallel supercomputers. Specifically my research is focused on the solution of systems of linear equations (both dense and sparse) on parallel, heterogeneous supercomputers in a reliable and scalable way where, by scalability, I mean the ability to solve systems of larger and larger size. This is achieved through the development and analysis of
algorithms that improve parallelism and the use of efficient parallel programming paradigms that allows for achieving high efficiency and performance on large scale parallel computers;
scheduling policies that keep the memory consumption under control in a parallel setting;
methods that can reduce the complexity of the solution, both in terms of memory and number of operations, at the price of a controlled loss of accuracy.
