Hi again, Wes,<br>
<br>
Does the shared memory allocation impact the memory available for
other AIPS tasks to use? Does it "reserve" that much memory for the
TV? Or are they independent? (If they impact the performance of
other AIPS tasks,<br>
I might want to not run on too many TV's at once). <br>
<br>
The FAQ also talks about improving overall AIPS performance on a
Solaris machine by changing the settings to the following - will
these help any on a Mac (OS X)?:<br>
<br>
<code>set ufs:ufs_HW=6291456<br>
set ufs:ufs_LW=4194304<br>
set priority_paging=1 </code><br>
<br>
Sorry if these are dumb questions.<br>
<br>
Thanks,<br>
-s-<br>

In short yes, you will need to increase the amount shared memory allocation. I would guess you would need to double everything but kern.sysv.shmmin. It may be that you can get by with doubling kern.sysv.shmmax but I'm not sure.

understand how shared memory works - do I need to
double/triple/... the shared memory value for
kern.sys.shmmax in /etc/sysctl.conf if I want to
use two/three/... TV displays at the same time? Is
there something else I should change? I'm running
with a 23 inch display, 1920 x 1200 pixels.
Thanks very much,
Susan
