We have been evaluating a 16 processor Prism for that last
couple of weeks. We are seeing if this is the hardware to
replace our 16 CPU ONYX Monster.
Using the 'gcc' compiler we get 'blazing
fast' OpenGL applications (mostly OpenGL based CAVE
applications). But any CAVE-Performer or 'raw'
Performer applications ran only so-so, about as fast
as an Octane perhaps.
We were told that using the Intel compiler would improve
thinks, but unless the Performer libraries are also
re-compiled in a more optimized mode for this hardware,
most of my applications (Performer based) will not see
much improvement.
Also.. We have system reliability problems (network
interface would freeze and console display would lock up).
The graphics drivers for the console are poor (geometry
has holes, low stereo resolution, geometry appears and
disappears when moving viewpoint). All this will be
'fixed in the next release' but is a sad sight after all
the previous solid and reliable UNIX systems we used
to get from SGI. We can get "buggy" systems from
anyone - especially MicroS... - so what is the reason
to specify SGI???
