[comp.parallel] Any more hyp. users out there?!

arhegde@vela.acs.oakland.edu (anupama hegde) (07/27/90)

 I have looked up this newsgroup several times with the hope of finding 
something interesting but it appears even hypercube cronies seem to prefer 
comp.parallel or some other similar(parallel!) group where you have to sift 
through piles of other stuff to find something on hypercubes - if at all.

 I am interested in interacting with people who are working with/on hypercube
architectures. I am engaged in the task of programming NCUBE's NCube/4 (2-D 
4 node hypercube) and would be delighted to get in touch with others like 
myself. Am encountering some problems and would appreciate the opportunity
to pick some more experienced person's brains! Or maybe I'll have some 
suggestions for you.

 Would also like to hear about experiences of other hypercube users.The 
recently held Ncube Users Group meeting at South Carolina triggered off an 
Ncube-users mailing list but I believe that will be inactive till Aug 18th. 

 Here's to a more active newsgroup...

John, you're exactly correct. The old comp.hypercube was formed first and
is still in the lists constructed by the news reader programs. The
submission point is still the same: it all comes to me. I post only
to comp.parallel.

The answer is no. The history is this. In 1986, I called for votes to 
comp.hypercube. It passed and I was made the moderator. In February or so,
there was a readership who wanted another group for general parallel, one
for hypercubes, one for CM's, ad nauseam.

We submitted the whole thing to a vote, one of the alternatives being
what is now comp.parallel.  It was, obviously, the comp.parallel proposal
which won out. Now, if I as moderator, try to post to comp.hypercube, it is
rejected. Don't know what happens if you try to post to comp.hypercube.

For the iPSC users, there is an mailing list run by Dave Fielding out
of Cornell. His old address is fielding@tcgould.cornell.edu. As far as
I know, there is not an equivalent NCube group. Perhaps someone from
NCube can enlighten us. There are several regular listeners/contributors
from Thinking Machines.

The policy has been that as long as it it not too blatent a commercial,
hardware and software announcements are posted to the net. This allows
us to keep up with the comings and goings. Demises get talked about through
normal gossip :-).

Any comments sent by follow-up will get to me.

yes, we've got a 16+1 (i/o w/ VME) node iPSC/2 cube.

Well, to keep this on the subject...

I've gotten my hands on VM_pRAY, and i've gotten it to generate an
output file, but i have no clue as to what or how to display it.  What
format is it?  Does anyone have any utilities to conver it it to say
sunraster, GIF, IFF, iris, etc...?

thanks a lot!!

You have two ways to display images from VM_pRAY. In the latest version
of VM_pRAY (VM_pRAYjul90.tar), the image format may be either ppm or
mtv.

	ppm (portable pixmap file format)
	    Copyright (C) 1989 by Jef Poskanzer.
	    utilities to convert ppm file (24bit) to
	    either sunraster, GIF, ... are available from
   	    ftp.ee.lbl.gov [128.3.254.68]: *pbmplus.tar.Z*. ,
	    via anonymous ftp
	    
	mtv (output  from  Mark  VanDeWettering's  ray tracer)

you can:

1) If you get the ppm package, a use of the ppm utilities may
   be 
	ppmquant 256 < image.ppm | ppmtogif > image.gif
	xloadimage image.gif

2) If you don't want to install the ppm package, you can use
   utilities from our site 
	irisa.fr [131.254.2.3]:  */iPSC2/VM_pRAY/color

	This directory contains programs to display an image 24 bits
	on 8 bits screen running under X window system:

	The routines generated accept the image format procuced by
	VM_pRAY (either mtv or ppm):

        Xnb:            display the image with grey level.
                        use:
                                Xnb < image.mtv
                                        or
                                      image.ppm

        Xrvb:           a simple program to display an image color.
                        (not very pretty but fast).
                        use:
                                 Xrvb < image.ppm
                                          or
                                        image.ppm

        comp24to8:      generate a 8 bits image color with a good
                        colormap compression. The 8 bits image is
                        stored as a sun rasterfile file.
                        use:
                                comp24to8 < image.rvb > image.ras
                                              or
                                            image.ppm
                        display:
                                xloadimage image.ras
