Researchers at the University of Minnesota recently developed a new delivery system for drugs that could be effective treatments for HIV (human immunodeficiency virus, which causes AIDS). MSI PI Professor Louis Mansky (Institute for Molecular Virology) is one of the co-authors on the study, which combines two FDA-approved drugs in pill form. Using pills is an improvement for the patient over most anti-HIV drugs, which must be injected.
This study was published on August 30, 2013 in the journal Antiviral Chemistry and Chemotherapy.The Minnesota Daily published an article about the research on September 9, 2013. It was also reported online in Science World Report and Daily News and Analysis.
Professor Mansky studies HIV mutation and how it affects the development of effective drug therapies. It is also thought that the mutation and evolution of HIV is responsible for the gradual breakdown of the immune system and the disease progression to AIDS. Professor Mansky and his group use MSI resources for several projects in this area.

Dr. Matthew G. Knepley, University of Chicago, will present a hands-on tutorial for PETSc at MSI on September 30. Dr. Knepley is one of the authors of the widely used PETSc library for scientific computing from Argonne National Laboratory, and is a principal designer of the PyLith library for the solution of dynamic and quasi-static tectonic deformation problems.
PETSc is a suite of data structures and routines for the scalable parallel solution of scientific applications, often modeled by partial differential equations. It supports MPI, shared memory pthreads, and GPUs, as well as hybrid MPI-shared memory pthreads or MPI-GPU parallelism.
The tutorial will be held on Monday, September 30, from 9 a.m. – 4 p.m. There will be an hour for lunch (12 – 1 p.m.). The tutorial will be held in room 575 Walter. Register on the Tutorial page.
As workstations are limited, participants are invited to bring their own laptops to use during the tutorial. Please visit the PETSc website and install the program. You can install the latest release, but the most up-to-date snapshot is preferred, which uses the “git checkout next” branch; download it on the developers site.
You can also view prior tutorials and a User’s Manual plus extensive additional documentation.
This tutorial will cover basic sparse parallel linear algebra, as well as linear and nonlinear algebraic solvers, and timestepping. Students will learn to use the dynamic configuration object system in PETSc, and use it to assemble hierarchical, multilevel solvers for multiphysics problems. The tutorial also includes how to debug and profile the resulting applications.
The morning session will cover basic usage:
- Vectors and Matrices
- Generic Solver Setup
- Dynamic Object Configuration
- Debugging and Profiling
The afternoon session will cover advanced usage:
- Structured Meshes Using DMDA
- Linear Preconditioning
- Structured Linear Multigrid
- Block Preconditioners
- Nonlinear Solvers
- Nonlinear Preconditioners
Matthew G. Knepley received a B.S. in Physics from Case Western Reserve University in 1994, an M.S. in Computer Science from the University of Minnesota in 1996, and a Ph.D. in Computer Science from Purdue University in 2000. He was a Research Scientist at Akamai Technologies in 2000 and 2001. Afterwards, he joined the Mathematics and Computer Science department at Argonne National Laboratory (ANL), where he was an Assistant Computational Mathematician, and a Fellow in the Computation Institute at University of Chicago. In 2009, he joined the Computation Institute as a Senior Research Associate. His research focuses on scientific computation, including fast methods, parallel computing, software development, numerical analysis, and multicore architectures. He is an author of the widely used PETSc library for scientific computing from ANL, and is a principal designer of the PyLith library for the solution of dynamic and quasi-static tectonic deformation problems. He developed the PETSc scalable unstructured mesh support based upon ideas from combinatorial topology. He was a J.T. Oden Faculty Research Fellow at the Institute for Computation Engineering and Sciences, University of Texas (Austin, TX), in 2008, and won the R&D 100 Award in 2009 as part of the PETSc team.
