Is it known to what extent the limitation on "fps's" is due
to (1) CPU power and/or (2) graphics speed? We are wanting
for a r4K upgrade for one Indigo and a ElanVideo option board.
I was planning to put these upgrades in different IRIS XS-24's
but I wasn't aware of the compression/uncompression scheme
for the movie software.

What sort of "fps's" should I expect from a r4K Indigo?

Thanks.

fsr's pretty careful about what it finds in /etc/mtab.

First the mtab entry must be of type "efs", the file system (first column
of an /etc/mtab entry) must be a block device and the file system must
be mounted "rw.  

In addition there must be a "raw" entry, it must really be a raw device
and it must match the dev_t of the file system.

Finally, if a given entry's "raw" file cannot really be open'ed O_RDWR
and/or is not really an EFS file system fsr exits immediately.

Note that raw for /usr3 and /usr2 is the same as the file system and
hence must be block -- assuming this is /etc/mtab as generated by mount(1).
Use "fsr -v" to see a warning about this as well as a whole lot of other
output about each and every reorg operation.

	Zip runs fine on both of our IRIS workstations. The problem comes when
I log onto one workstation from the other. Running zip on the remote machine and
editing a file residing on the same remote machine, with the local machine acting
as the display server, I find that Zip runs INCREDIBLY SLOWLY. In fact, it is all
but unusable in this mode.

	Is this a problem with running a GL application over a network? Any way
to alleviate this problem?

   A strange request, I know. But I just can't get a full-blown database,

For about $1K per seat, you can get CASEVision/Tracker (from SGI).
It's marketed as a bug-tracking system, but bug tracking is DBMS work,
and its easy extensibility should make it do what you're after.

Tracker includes:

	- OSF/Motif GUI with query-by-example, including ranges,
	  regular expressions, a rich assortment of date formats, etc.

	- CASEVision/Scheme support (allows you to control fonts,
	  colors, etc. in a coordinated yet personalizable manner).

	- Completely flexible, totally easy definition of fields,
	  screen layout and appearance, etc.

	- Process extensions allow you to control what people can do,
	  if that's important (doesn't sound like it is for your
	  situation)

	- On-line, context sensitive help, which the designer of the
	  application can write or extend while doing the screen
	  layout and the like, to keep the end users out of trouble.

	- An SQL-like scripting language, for the DB wizards.

	- Simple shell command-line reporting tools, for the shell

I set up an Indigo R4000 for someone in our department last week, and
looked through some of the new demo stuff (the "Tour").  In one part,
there is a screen snapshot of a program called InSight(?), which is
described as a hypertext manual searcher/browser.  According to the
demo, it comes with the text for all the standard Iris manuals (and
I'd guess others could be added).  It is described as if it is already
available, but I couldn't find it on the IRIX 4.0.5F CD that came with
the machine.  Is this a finished product, or soon-to-be-released?  Is
it going to be part of the standard IRIX distribution or will it be
sold as a separate product?

The 4.0.5F release also includes some new multimedia stuff (the movie
stuff) that wasn't on the 4.0.5A CD.  The 4.0.5F CD is marked as being
specific for R4000 Indigo and Reality Engine systems; does that mean
that there won't be a general distribution of these tools until the
next release of IRIX?

Finally, is the old(er) 3.1 compiler CD equivalent to the new 4.1
development option CD?

  I had an interesting experience with SGI's support Friday.  

  We had been very impressed with the CodeVision (now
CASEVision/Workshop) and bought a copy of it, along with an Indigo to
run it on. We had it installed and running nicely with the temporary
licence. The permanent licence, however, didn't arrive, something
having been lost somewhere along the line, so we had to re-send the
request and get one faxed to us.
  When I tried to install that licence, it didn't work, so I followed
the instructions on the accompanying sheet, which said one could send
e-mail to license@esd.sgi.com.

  Since the machine is in a lab and the phone there can't call
long-distance, and because we're 3 hours ahead of SGI I thought e-mail
support for licence problems was a great idea and sent mail to that
address Sept. 10th. On Sept. 22nd I got a reply, which said to call
the hotline.  The hotline said that the warranty on the Indigo had
expired the previous day and I was out of luck trying to get the
software installed. After some discussion, since I had been trying to
do something about it previously, they did graciously agree to help me
out just this once.

  We got a call id, somebody called and we were able to identify the
problem. It appears that CASEVision/Workshop and CASEVision/ClearCase,
despite the implication from the names that they are part of the same
family of products, cannot have their licenses installed on the same
machine, due to a bug in Workshop 1.1.  SGI has promised to FAX us a
new licence for Workshop so we can run it off our old 4D/25, but
we haven't got it yet.

  I realize that SGI charges for software support, and I think this is
entirely reasonable, especially for operating systems and software
like Showcase and Explorer which they are effectively giving away.
However, when we pay a substantial amount of money for products like
Workshop and ClearCase it does not seem unreasonable to expect some
support independent of the machine they happen to be running on,
especially for bugs in their license servers.

 To me, this is a strong motivation to minimize our dependence on
ClearCase on the SGI machines, and use the Sun version, for which I
can get support (including support by e-mail) directly from the people
who actually make the product. With Workshop we're stuck for the
moment, but I certainly intend to look for alternatives.

Revo uses the examiner viewer, which is the same viewer you get in the
SceneViewer by default. The SceneViewer alows you to switch to the other
viewers though, in addition to doing picking, editing color/matrial and

changing the scene graph during an action traversal is indeed very bad,
and I am not sure why you are doing this. What you should do is have 2
graphs. One for the revo outline (which you said was in a seprarte window)
and one for you final 3D object. Instead of displaying the 3D object in
the examiner viewer (what Revo does) you should have no problems
displaying it in the sceneViewer. As the outline of the shape changes, all
you need is to change the coordinates of your 3D shape, which will be ok
since those are 2 separate scenes. Maybe you getting the segmentation fault
for something else (check what dbx stack says).

I'm not quite sure about what a bullet is :-), but I assume You talk
about a dot that is a little thicker, right? (Wes said something about a
bullet looking like, but not being a filled circle). I just tried
Showcase 2.0 on IRIX 4.0.1 and succeeded in getting the bullet character
(as I hope it is) by typing <Ctrl>-<Alt>-8. By additionally pressing the
<Shift> key You get a smaller bullet. (I just had a look into my dictionary
and it says that we seem to talk about the same thing (bullet) :-)

You are correct.  Originally, it worked as described with jagtape, and
it was planned that tpsc would work that way too.

For 4.0.3, we changed jagtape to write out filemark(s) on close
after either writes or write filemarks.  To the best of my knowledge,
tpsc always worked this way.

Unfortunately, the man page fell through the cracks.  Sorry.

For the next major release, no changes to this protocol are planned,
so it should stay consistent.  I will make sure that the man page
is fixed.

We just got our first Indigo R4000 with the IRIX maintenance 4.0.5F CD.
I have two questions:

1) I'm trying to run the fx utility from the CD so that I can 
   format the only disk (external 3rd party) on this 
   system, and the prom command interface seems to be different on
   the Indigo R4000 from R3000. For example on the R3000 I would do:

       boot dksc(0,4,7)/stand/fx.IP12

   However this does not work on the R4000 (I replaced IP12 with IP20).
   Also hinv shows the devices as scsi(0)dsk(4)rdsk(0)..... which is
   different from the R3000 "dksc" naming scheme. How do I run the
   fx utiltity and also how do I specify the controllers/devices/
   partitions with the R4000?

2) Is this CD supposed to be a complete IRIX distribution, or do
   I need another IRIX CD like 4.0.1, and then install the 4.0.5F
   after installing 4.0.1??? Is the fx utility included?

Thanks for any help. I'd like to have this system up and running
before the first SPARCstation 10 (model 20) on campus which arrived
on the same day, and run my benchmarks!

I need to set up an Indigo, IRIX 4.05, to boot itself
and run from 3 different network connections, using
a different ip address & name with each of them.  The
networks, gateways, and ip addresses are:

134.174.143.xxx 134.174.143.1 134.174.143.34   
134.174.146.xxx 134.174.146.1 134.174.146.7    
134.174.153.xxx 134.174.153.1 134.174.153.62   

The machine will be moved from one place to another, and 
powered up, by non-tech types, for lecture demos, lab
sessions, and so on.  Thus I need to have it select
it's network persona & configure itself automatically, 
when it boots up, according to what it can see over its
ethernet connection.  What's a good way to do this?

Thanks in advance.
