What's new

What's old

May 11: Info from Jim Scott on physically realistic constants for nbody problem

May 6: In addition to retriever.cs, MPI is now also "installed" on umbc8/9, in my home directory. On either machine, the mpi distribution is in ~motteler/mpich"; an example program "bogey.c" and makefile are in ~motteler/mpitest. The program to launch a set of mpi jobs, "mpirun", is in ~motteler/mpich/bin. You are limited to a total of 5 processes (your current process plus four more created with rsh, all running on the same machine) by default; this can be changed if you want to customize your own "machines" files. See mpich/doc/guide.ps and install.ps for more information on customization.

April 27: A short description of Project 3 is now available.

April 9: a more detailed discussion of the bitmap image display for project 2 is now available, and the specification has been simplified. A section containing general hints and suggestions has also been added. See the project 2 description for details.

April 8: test data for project 2 is available; see the project 2 description for details.

April 6:

• the project 2 description has been updated to include default values, information on image pixel encoding, and a simpler "zoom" specification
• more documentation for the image client/server is available
• the man page for the image client/server has been updated
• the image server has been updated to read a colormap
• a simple test program "itest" has been provided, that generates a sequence of images that can be used with the image client (in place of, e.g., the n-body program) to test the client-server link.

March 16: A calendar (basically a list of due dates), a list of study questions, and a description of project 2 were added.
