Marketing by the MPI groups? More to the point, it looked like MPI had
significant backing. I don't know if it was "better" in a technical
sense (though some folks do argue strongly about MPI being "better").

It was nice in that I could run huge (at the time) jobs on my 16 MB ram
PC. I remember running on one of those "sparc" units and this PC, and
the PC was about the same speed (molecular dynamics). The brand new
R3000 shiny SGI Indigos with a whopping 192 MB of ram and a huge 1 GB
disk, these were great to work with. Much faster. Could do 100 time
steps of MD in a week.
FWIW, I can do about 1 time step in less than 20 seconds on my laptop
(AMD Athlon 64 2GHz chip)...

heh... OS2 was quite a bit better than win31. Somewhat better/more
stable than w95/w98. It just never caught on in any meaningful sense.
And about the time it tried to pick up momentum, Linux got to be
installable/useful. I remember my first laptop (self purchased) had a
75 MHz pentium processor, a 2 GB disk, and I ran windows, OS2 and Linux
(RH in the pre-5 days) on there. Pretty soon after that, OS2 fell off.
