[comp.databases] Seeking Parallel Programs to Study

aglew@oberon.crhc.uiuc.edu (Andy Glew) (07/26/90)

{To comp.databases: I am not sure if this has already gotten through
to you.  News needs work on the interaction of moderated newsgroups
and lists of newsgroups to post to. :-( }


This is another of those "Looking for ... programs for my research"
broadcast questions, with a twist: I have collected a number of
programs that I may be able to give others, or at least that I can
point to the authors of.


I am looking for parallel programs that I can use as subjects for
experiments in computer architecture (synchronization).  Ideally these
would be written in C, and run on an Encore (or a Sequent).  If they
use a non-vendor provided threads package, I'll need a pointer to
where I can get that threads package. (Explicit parallelism
preferred).



I already have (and am willing to provide to others, if it is okay
with the original authors):

    gravsim
      An N-body gravity simulator for galactic dynamics,
      written in C, runs on Encore, Sequent, Alliant...
      Written by mbellon@urbana.mcd.mot.com

    locusroute
    pthor
      Unfortunately, I have not yet succeeded in 
      getting these to work on our Encore.  My copies
      are old and grotty.  Can anyone point me to fresh
      versions?

I have several others that I am not yet certain that the authors wish
to have distributed.  I'll ask. If it's okay, I'll post.
    I will respond to a reasonable number of email requests,
but if it becomes overwhelming I will get these put in UIUC's 
anonymous ftp area, and then post where they are.



So, having exposed myself to lots of "Give me everything you've got"
requests, does anyone else out there have any other parallel programs
that they would be willing to let me take measurements, traces, etc.
of?
    I am particularly interested in non-scientific applications, since
the biggest market for Sequent style applications seems to be
databases.  Unfortunately, I cannot buy a commercial database, but is
there any public domain multiuser database code out there that uses
the client server model, or parallelizes queries, or....?  Multiuser
games, military simulations - anything using a shared memory model.



Trusting in the net and serendipity...

Please email responses: many of these newsgroups I do not get to read
as often as I would like.

Propaganda:
    
    UIUC runs the "ph" nameserver in conjunction with email. You can
    reach me at many reasonable combinations of my name and nicknames,
    including:

    	andrew-forsyth-glew@uiuc.edu
    	andy-glew@uiuc.edu
    	sticky-glue@uiuc.edu

    and a few others. "ph" is a very nice thing which more USEnet
    sites should use.  UIUC has ph wired into email and whois (-h
    garcon.cso.uiuc.edu).  The nameserver and full documentation are
    available for anonymous ftp from uxc.cso.uiuc.edu, in the net/qi
    subdirectory.
