Could anyone please tell me where I can find a solver (subroutine) to solve this partial differential equation? Thanks a lot.

The conference will provide a forum for users from industry, national laboratories, and academia who are using MPI to present their ideas about, and experiences with, MPI. SCOPE: Examples of appropriate topics for this conference include: o) Applications using MPI o) Implementations of MPI o) Experiences with MPI o) Extensions to MPI o) Why MPI is better/worse than other message passing systems o) Message passing versus shared memory o) The future of message passing o) Software issues o) Anything else about MPI, message passing, or parallel computing SUBMISSIONS: Abstracts are solicited for: 1) Papers 2) Posters 3) Panel discussions 4) Software demonstrations TUTORIALS: Two pre-conference tutorials on MPI will be offered on June 29 and 30, 1996. The first tutorial, on June 29, will cover the basics of MPI including point-to-point and collective communication operations, and communicators. The second tutorial, on June 30, will pick up where the first tutorial left off and will cover data types, topologies, and intercommunicators. Attendees may take either or both of the tutorials. Both tutorials will be conducted in one of Notre Dame's SPARC-based instructional clusters where each attendee will have use of a workstation throughout the tutorial. The tutorial lectures will be interspersed with a series of exercises requiring each tutorial attendee to write, debug, and run MPI-based programs using C or Fortran. DEADLINES: Abstracts for papers: April 26, 1996 for posters: May 24, 1996 for panel discussions: May 24, 1996 for software demonstrations: May 24, 1996 Papers for proceedings: May 31, 1996 Lodging reservations: June 10, 1996 Early registration: June 10, 1996 FOR MORE INFORMATION: Complete and up-to-the-minute information about the conference can be found on the Web at http://www.cse.nd.edu/mpidc96/ or contact Andrew Lumsdaine Internet: Lumsdaine.1@nd.edu Computer Science & Engineering Phone: (219) 631-8716 University of Notre Dame Fax: (219) 631-9260 Notre Dame, IN 46556 ------------------------------ From: National Semiconductor Date: Tue, 26 Dec 1995 09:26:36 -0800 Subject: Positions at Numerical Semiconductor Two positions available in Numerical Semiconductor Device Simulation Two positions relate both to software development engineering in the cases of two distinct simulators. 1. A current generation 2D Trianglular and 3D prismatic, Fortran and C package. 2. A next generation 1D, 2D, 3D C++ Tetrahedral simulator. Simulator 2 currently includes a lot less physics that simulator 1. The position is available immediately and is located in Santa Clara, in the center of Silicon valley, California. A description of this post is available on http://www.silvaco.com Experience of both numerics and device physics is required. email: personel@silvaco.com ------------------------------ From: Richard Brualdi Date: Tue, 26 Dec 1995 11:56:02 -0600 (CST) Subject: Contents, Linear Algebra and its Applications LINEAR ALGEBRA AND ITS APPLICATIONS Contents Volume 234, February 1996 Michael H.
