grid computing   
What is feasibility of using neutrino vs bsd/linux?
What would the most powerful hardware platform be?
What kinds of applications would be suited to a neutrino cluster?

RE: grid computing   
Pretty fishy and open ended question ... tongue in cheek answers below

Very feasible ... most anywhere Linux|BSD can go, Neutrino can 
also go.  Further to that Neutrino has built in scalability in 
the form of an standard POSIX API that allows you to build 
distributed clusters today without making any changes to you
applications to use specialized communication libraries.

Not really an answerable questions.  

> What kinds of applications would be suited to a neutrino cluster?

Anything suitable to any other cluster.  Large scale distributed
computations to multi-user entertainment systems for use in transport 
operations (ie in-flight entertainment).

Re: RE: grid computing   
Thanks for your comments.

The HW platforms supporting LINUX are pretty heavy duty machines.
It's running on POWER and ITANIUM processor families with dozens of cores.

I don't see any HSP's for Itanium but at least 32bit powerPc is runing neutrino.

Has anybody run QNX on the new 8-processor MAC Pro?  This would seem quite powerful when clustered. Neutrino is running 
on Xeon processors in other boxes, right?

I'm looking at moving an application from an HP superdome to a QNX cluster.

Re: RE: grid computing   
Or how about this monster:

IBM* System x3850 M2 Server platform with four Quad-Core Intel Xeon processors X7350 2.93GHz, 2x4MB L2 cache, 16 x 4GB 
DDR2-PC5300

Re: RE: grid computing   
As far as I know QNX will not run on Intel Xenon machines. I tried to run it on a machine comprising of an Intel Xenon 
W3520 (Quadcore) with a  ICH10R/D0 southbridge (http://community.qnx.com/sf/go/projects.community/discussion.community.
topc13051), however I wasn't even able to install it.

RE: RE: grid computing   
Runs fine for me, the issue is NOT the processor.

Re: RE: RE: grid computing   
Yeah, maybe it's rather the southbridge than the CPU which causes problems.
I'll try the QNX 6.5 pre-release, maybe that version will run out-of-the-box.

May I ask which hardware (CPU + southbridge + northbridge) you used for successfully running QNX on?

QNX Neutrino runs on any x86. If it's not possible to install it, the reasons are somewhere in startup code or PCI 
server. Usually QNX can fix that.

With 6.5, it's said to run on machines with up to 32 cores, however I haven't heard of the machine this was tested on, 
yet.
