Subject: Current State of MGNet

Things have been awfully quiet this summer.  I have quite busy on something
and have not pushed on people to contribute anything here.  I will have some
spare time each week to devote to pestering people about multigrid issues, so
I am going to try to revive this mailing list much more often than once a

Currently, there are packages contributed by Bandy and Dendy (boxmg), Bank
(pltmg 6.1), GMD (amg, mg000, and mg01), and myself (madpack 2).  Several
others have made promises, but have not yet delivered (ahem).

Subject: Research Reports

Besides just getting codes deposited, I would appreciate it if people would
send titles, abstracts, and how to get your recent research reports to this

If you would like to leave a copy of a report at the repository, there is
plenty of disk space.  I would prefer people leave a report as a .dvi file
(the output from some flavor of TeX) unless there are PostScript inclusions.
If the paper is deposited as a Postscript file, a .PS file extension would be
appreciated.  If you are using some other text processing system, use whatever
seems appropriate (please make it obvious).

If you leave something there, please remember to get it removed once the paper
is published...

To leave something in the mgnet repository, do the following:

    % ftp
    Connected to CASPER.NA.CS.YALE.EDU.
    220 casper FTP server (SunOS 4.1) ready.
    Name ( anonymous
    331 Guest login ok, send ident as password.

Use your e-mail address or anything that catches your fancy.

    230 Guest login ok, access restrictions apply.
    ftp> cd mgnet/incoming
    250 CWD command successful.
    ftp> mkdir douglas

Use your last name (or something distinctive) instead of douglas.

    257 MKD command successful.
    ftp> cd douglas

Use what you used in the mkdir command.

    250 CWD command successful.
    ftp> put p.dvi

Put some file (if it is in binary, issue a binary command before doing this).

    200 PORT command successful.
    150 ASCII data connection for p.ini (,1097).
    226 ASCII Transfer complete.
