Subject: Need Help With a PDE

Hi, everybody,

I encountered a partial differential equation,

       Dq       Dk
      ---- = - ----
       Dz       Dt
in which "D" means partial derivatives and

q = -------------------------
1 + b(z) + c(z)*k^2

This differential equation actually stands for kinematic wave in general.

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

Thanks a lot.

Subject: MPI Developers Conference and Users Group Meeting

MPI Developers Conference
Users Group Meeting

July 1-2, 1996
University of Notre Dame
Notre Dame, IN 46556

The MPI Developers Conference and Users Group Meeting is a conference
for all users of the Message Passing Interface (MPI) standard and is
intended to support the continued development and use of MPI and its
extensions. 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.


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


Abstracts are solicited for:
1) Papers
2) Posters
3) Panel discussions
4) Software demonstrations


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

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

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

Experience of both numerics and device physics is required.
