:First of all compatibility of Performer with IRIX 6.0.
:Do applications in Perfomer 1.2 run on IRIX 6.0 with or
:without re-compiling?
Yes. But they run in 32-bit mode so there is usually no
performance advantage.
:And will Performer 2.0?
Yes.
It will support all three cases:
32-bit IrisGL: all machines including R8000
32-bit OpenGL: all machines including R8000
64-bit OpenGL: R8000 only
Note that 64-bit IrisGL is not one of the choices.
:Will Performer 2.0 be compatibile with programs written
:for 1.2?
Mostly. We try to never break old programs through a
combination of only making additive API changes and
providing thorough conversion tools (like the port1.2
sed script that shipped with 1.2). There are cases, though,
where some programs will have to be changed. We will
describe these in the release notes that ship with 2.0.
:Is Performer 2.0 on schedule and will it be released in
:April as was written some time ago on the forum?
We are arguably on schedule, though there is still much
work to do. We still plan to have 2.0 in customer's hands
by April.
:Regarding the new Audio/Serial Option board for Onyx, is
:there anyone who is currently writing some 3D sound library
:for it? Will it be included in Performer 2.0?
It's usable with SGI's Audio Library, and SGI Audio Library
programs already have been written that work with IRIS
Performer, so the answer is yes. One example is the OORT
game that ships with IRIS Performer 1.2.
:One last question about Performer & REACT.
:It seems to me that REACT will be an add-on for the OS
:starting from IRIX 5.3. Is it correct?
The basic REACT facilities that have been provided with IRIX
in the past are still provided for free. These include non-degrading
priorities, processor assignment & isolation, and the many other
MPADMIN/sysmp() functions that you may be used to.
What is new is REACT/Pro, an extra cost suite of tools that
includes the new frame scheduler and advanced profiling tools.
Contact Ralph Humphries (ralphh++at++asd.sgi.com) for full details
on these questions.
:And will it impact on Performer that use it?
:How are the relationship between Performer and REACT?
They are compatible and have several relationships now in
development for the IRIS Performer 2.0 release.
