[AG-TECH] Vic thoughts

[Michael Gates]

MessageWe were having a similar problem with our display machine (not even
PIG).  We discovered that we only experienced this problem on a single CPU
machine.  As soon as we setup on a dual CPU, the problem went away.  The
single CPU was a P4 1.8GHz, and the first duals we setup without the problem
were P3 600Mhz.  Maybe the code is geared for dual CPUs?

hope it helps,
-Mike

  To clarify the below, our problem seems to be a CPU utilization one.  With
only a few windows open, or even just one with substantial motion in the
video stream, the CPU time required by OM Vic skyrockets to 100%,
effectively disabling the machine.  In contrast, the v2.8nlsde-2.1.3-1114v
version of vic utilizes the CPU much more efficiently.  Any suggestions on
how to improve this would be appreciated.  I should note that the settings
we are using are h261 compression at 29fps and quality of 1, in case that
affects things.

  Thanks.

    We have been doing a lot of work lately with the various versions of the
PIG - vic.exe on Windows 2000/XP.  We have found that when opening more then
4 windows the only version that seems capable of performing exceptionally
well is the v2.8nlsde-2.1.3.-1114 version of vic.  If we use the Open Mash
or the vic.exe (DD or without) off the AG site - the applications run but
seem to hang or skip on a computer when opening more then 4 windows at once.
Has anyone experienced this?  If so, do you have a work around?  We are
using the NVIDIA Quadro4 Video cards with 128MB of Video Memory.

    thanks -
