Subject: all available memory for one process
Date: 5 Nov 92 15:06:55 GMT
Organization: University of Pennsylvania

One of my users has an SGI with 128 MB of memory, and a single
program that he would like to lock in as much of that memory
as possible, at the expense of all else except the operating 
system. I've looked at the tuning part of the admin manuals, 
but am wary of changing per process limits in the kernel because
of hidden dependencies I may not be aware of.

Does anyone have experience or suggestions or war stories on
doing this?

Thanks, John

Hidden line removal is pretty easy with stencil planes.

The basic idea is to draw each polygon first as its
outline in the wire-frame color, and then draw the
interior (filled) polygon in the background color.  This
will clobber any lines behind it (assuming you're using
Z buffering, of course).

The problem is that the polygon interior may also
clobber some of the outline and your picture will look
pretty raspy.

To get it right, for each polygon, clear the stencil
plane, draw the outline in both the stencil plane and
in the framebuffer, then draw the polygon's interior
at only those points where the stencil plane is still
clear.  Thus the outline can't be clobbered by the
interior.

This will be pretty slow if you clear the stencil
planes after each polygon, but note that they can be
cleared after the first time by simply drawing the
outline again, and erasing the stencil plane whereever
the outline occurs.

I have a problem that I know people on the net have solved.  As a matter of fact, most of the
problem is setup.  I have a Panasonic SVHS AG-7750 with TBC and AG-F700 time code generator/reader,
Videomedia VLAN transmitter and reciever, and an Indigo XS24.  I have been trying for 3 days now to
send a play command to the VCR from the indigo and have it work.  I am sure there is a setup 
problem somewhere along the line.  The VLAN commands look to be very trivial.  I am almost positive
that I have the VCR set up incorrectly.  Would someone with a AG-7750 and VLAN please send me the
switch and menu settings for the VCR and any special commands for the VLAN (ie an example of the 
play command or a single frame record).  Could you also describe the cable connections between the
VCR and the VLAN.  If there is anything special on the computer side that I should be doing, I would
like to hear that as well.  Any help at all would be greatly appreciated.

Thanks

I have had a few go-arounds on this one.

Memory pigs may be killed by IRIX.  The algorithm for death is
unpublishable ( so I have been told ).  The process is sent an
uncatchable signal, is expunged, and a message is place in
/usr/adm/SYSLOG by the kernel.

Thus, the only way to detect this type of action is to make your own
operating system of sorts.  Not too difficult.  Process A gets a slice
of shared memory, and a semaphore, then it forks, sets a timer and
stays small.  Its child, B, puts the date in the slice of shm, and
sets the semaphore, sets a timer, and grows big.
Process A wakes, checks the shm,  If date is old, A checks SYSLOG for 
message of death of B.  Date not old, process A wakes, checks the shm,
and if its ok, resets the semaphore, and sleeps.  
Process B's timer goes off, and it resets shm and semaphore.  
They continue merrily along
Process B eventaully dies, A finds old date, no evidence in SYSLOG, 
concludes B has died a natural death, and kills itself after it cleans
up its semaphore and shared memeory.

The meaning of 'old', 'date', 'timer', and 'sleep' can be tailored as
needed.

Presently there is no way to rotate a text object in showcase version 2.

One work around however, is to open a new showcase document, input a 
line of text.  After entering the text make sure it is selected.  Go to the File-->Save As-->As EPS menu selection.  Provide a file name and when prompted
whether to save entire document or selected item(s), choose only selected 
items.  This has taken your one text object and saved it as an EPS file.  Now
open up you main showcase document (the one containing your plots).  Do a
File-->Insert-->EPS menu selection and import in the EPS file you just 
created.  The imported EPS object can be rotated and in this case the line 
of text which it contains is rotated.

Logical volumes don't seem to work under 4.05F on a R4K indigo.
Here's what I did to create logical volume.

1. created the file /etc/lvtab with the following entry
   lv0:First Logical Volume:devs=/dev/dsk/dks0d1s6,/dev/dsk/dks0d2s7

2. ran mklv to create the logical volume ie. mklv -f lv0

3. grew the file system into the logical volume, ie. growfs /dev/rdsk/lv0

4. changed the entry for /usr in /etc/fstab, ie.
   /dev/dsk/lv0 /usr efs raw=/dev/rdsk/lv0 0 0

5. ran fsck ie. fsck /dev/dsk/lv0

Up to here every thing was fine. When I tried to reboot the system I got the
following error message:

Relocation error: relocation of a JUMPADDR overflows
Unable to load boot file: Invalid argument
Autoboot failed
Unable to continue, press <enter> to return to main menu.

Does anyone know what's going on? Dave Olson - help!!!!!

Subject: Problem with xdm, userenv, and zsh (and tcsh).
Organization: McGill Research Centre for Intelligent Machines
Date: Tue, 10 Nov 92 22:30:18 GMT

My apologies if this is a FAQ. I remember seeing some discussion about non
standard login shells but I cant recall the details.

I've been using zsh for a while on our Suns and quite like it so I thought I'd
make it my default shell on our SGIs (compiles without a hitch).

When I do this I have no problem with rlogin, but I cannot get my xsession
started via pandora.  It simply times out and returns to the login widget. I
can login via pandora if I use FAILSAFE after my username.

The problem appears to be `userenv` executed in xdm/Xsession.  When I invoke
the command from a shell (it doesnt seem to matter what kind) I get

	% uname -a
        IRIX Obelix 4.0.2 02211459 IP12
        % userenv
	zsh: suspended (tty input) userenv
        % jobs
        [1]  + suspended (tty input)  userenv
        % fg
        [1] - continued
        zsh: suspended (tty input) userenv

and so on.  Its as though userenv keeps sending itself TSTP.

Also I have been using a tcsh for some time now and haven't had this problem.
However when tcsh is my login shell userenv doesnt hang, but it doesnt print
anything either (which might explain a few probs I've been having with my
toolchest environment). So it looks like userenv doesnt work for tcsh either.

Does userenv only work with sh and csh?  Does this mean that I *must* make
either /bin/{sh,csh} my default login shell, or are there some configuration
problems.

It's true, since FSN was written as a prototype, not a supported product,
it does require Z buffering and RGB.  As Peter said, XS without the Z
buffering hardware does not support Z buffering.  The only reason it
is complaining about RGB is that it uses one message for either problem.

Here is a code fragment that can help.


#include <sys/syssgi.h>

/* check whether fastclock and timer were on before I started */
/* note that there is no way to query the fastclock is on,    */
/* but the timer cannot be on if the fastclock is not.        */

Fast clock does not incur nearly the overhead of timers, but I don't have a
relative number. I've been assured that it is of neglible impact.

Almost all. I couldn't install it on 4D/20 (R2k). Inst on the 4.0.5F disc
would hang the machine; inst on an earlier (4.0.5A) disc would come up,
then complain that it couldn't tell what some of the products on the 4.0.5F

No, I'm not really complaining (well, maybe just a little bit :)

You can also run Xapps on the NeXT without difficulty.  It's just
that there are few reasons to do it.  CAD might be the only reason.
What you win with NeXT is the level of integration and usability of
the applications.  There is nothing like it on any platform, just like
for 3D performance and support there is nothing like SGI!  

For a business user NeXT is probably a better machine.  But just the same
I was sorry to see the Indigo do so badly in the rating scheme, and as for
the others well you won't catch me going back to a single user 1 task machine

I once watched helplessly while IRIX killed most of the processes on the system
trying to get rid of a memory pig. The thing is, it already had, but it wouldn't
quit. The system was a 16MB Indigo running 4.0.5F with 40 MB swap space, and I
had tried to run a Fortran program that by mistake (mine, that is) would have
needed over 300MB to run in. The offending program was killed within a minute.
After that it was slow death, I tried to stop the process remotely but was
thrown off. The last entry in the syslog said that klogpp was killed due to
insufficient swap space.

BTW, I was running as an ordinary user, not root. Should I have reported this
to the TAC?
