When I read this posting I had to laugh. Jerry is OK with their PC
software, but he's way over his head when it comes to the UNIX based products.

We have been pushing Motion Analysis to move to Solaris 2 for some time.


Where to begin?

First, let me introduce myself. I am the System Administrator at the
University of Calgary Human Performance Lab and one of the co-writers of
KinTrak, (marketed by Motion Analysis, but developed here at the University
of Calgary). As system administrator, I have moved a few of our systems to
Solaris 2, as well as having added a few Silicon Graphics (SGI) workstations to
our network. I have also had the dubious honor of getting Motion Analysis
software working on our Sun network. Our network consists of about ten SUN
SPARCstations (three of which run Solaris 2.4, the rest SunOS 4.1.x), three
SGI workstations, and one SGI two-processor server. We also have about
twenty PCs on our subnet, as well as three MACs. The SGI server is a very
recent acquisition, and will replace our old SUN 3/280.


There is no problem whatsoever, in having Solaris 2 and Solaris 1
machines talking to each other. If there were, SUN would be out of business.

EVa (v1.10) runs just fine under Solaris 2.4. While I have not used it
extensively under either operating system, I have done some experimentation and there are some things that work even better under Solaris 2. For instance,
the automounter under Solaris 2 doesn't have the annoying habit of putting
all the mounts in /tmp_mnt, so when you do a "pwd" in /home/byron it replies
/home/byron, not /tmp_mnt/home/byron/byron, which is what I get under
Solaris 1.1.1 and IRIX 5.3

I am also assured by Tom Whitaker (CEO M.A.Corp.) that EVa will be compiled
for Solaris 2.4 in the very near future which will make it run even faster/
better. I also understand that they are seriously looking into Silicon
Graphics as a supported platform. (I'd love to see EVa track a 17 segment
full body (51 markers) with six cameras on a SGI Power Indigo2 Extreme)
Heck, I'd love to have the system, never mind the tracking ;-)


For those of you running KinTrak...KinTrak 5 was developed under Solaris 2
then retro-fitted to run under Solaris 1.1.1 and is currently in BETA release.

EV also seems to work, though I have not actually done anything useful with it.
I did plot a couple of files, and went into the tracker. It all looked OK.

Anyway, if you don't have any other software holding you back, don't let
EVa stop you from moving to Solaris 2.4! If you're running KinTrak 4, I
apologize: Certain SunView features don't work under Solaris 2.
