Andi,in case of IRIX it was a more of a problem of resources.
Here i think Intel may have some role in funding quicktransit and the quick transit guys had help from our kernel developers to make sure the performance of this product is really competitive.
This is just being used to bring apps from irix to linux mainly in the graphics side .
Some of those apps dont even have any source code left !!!
Some of others have been ported from irix to windows by ISVs but they dont believe in linux yet.
So this proves to be a good starting point for encouraging them to run it on Prizm first and then coax them to port it over to Linux.
Of course,Quicktransit cant help apps which use the Irix real time features,xfs GRIO features or IR(Infinite Reality) specific hardware hacks
Byt hey something is better than nothing
And the first few weeks of running Maya on Prizm under quick transit,it was already faster than a IR based system.
Now then what would happen if this app was running natively on IA64 Linux is what excites us.
