Performance comparisions between Linux and HPUX11i
-Will there be any performance difference between an Itanium Server (HP Integrity Superdome Server with new sx2000 chipset with 64CPUs) running Linux and the same server running HPUX11i.
-Will a 64 way server having Itanium processors running Linux perform better than a PARISC server with same number of CPUs running HPUX.
-Can Linux run on a 64 way PARISC machine as efficiently as HPUX11i?
Can anybody please answer or point me to a source for the answers.
Regards
Srikrishan

i have this (difference by OS), the admin difference.

but nothing like hw performance.

Re: Performance comparisions between Linux and HPUX11i
Linux won't run on PARISC at all. It only runs on Itanium servers.
Being certified in both OS's the issue is not necessarily perfomrance but rather reliability.
I've found a lot of non-production code in Linux that never makes it into production HP-UX releases.
The 64 way Linux system will probably outperform the PA-RISC system on HP-UX because HP is in the process of phasing out PA-RISC over the next 8 or 9 years and new chip releases are either on the market or the last release is soon to be there.

Re: Performance comparisions between Linux and HPUX11i
From perfomance/cost perspective, AMD operaton is more perferred than Itanuim.

Re: Performance comparisions between Linux and HPUX11i
Anyway, there is PA-RISC linux - www.parisc-linux.org - but I don't know that it runs on the big PA-RISC 'Domes. Also, while HP provides assistance to the effort, parisc-linux is not an officially supported thing.
As for the rest, the answer remains as it was in netnews - have your sales rep schedule some time in one of the solutions centers and make the direct comparison with your applications and the OS revs of your choice.

Re: Performance comparisions between Linux and HPUX11i
Here is whitepaper that may help...it doesn't compare OSes on the same hardware but gives some compiler performances on different hardware.

Re: Performance comparisions between Linux and HPUX11i
SGI has done a great deal of work on this, but in form of proprietary patches that are not soon to be in the upstream kernels.
I think right now noone can tell how long it will take until linux scales as well as one is used to it on smaller systems.
Note: if You're running Your Superdome as multiple Npars of like 8-16 CPU's, this should be a non-issue.
As already said, the overall performance will be nice, the current IA64 breed comes with a _LOT_ more cache, clockspeed and a n times faster system bus than what we get for PA-RISC; also many people have been working to optimize Linux for IA64.
Stay away from Linux on PA-RISC, only debian managed a reliable and working distribution, but the performance is 'suboptimal', also most current systems are far from being supported.
Some might remember HP's Linux-on-PA-RISC efforts in the end-90s, those have vanished silently. :)
[ Personally I'd advise anyone to keep running HP-UX on SuperDome missionb critical tasks and i.e. change to TCOE if license cost is an issue. And vice versa, use high-workpower Opteron 8-16x systems on Linux for not-so-critical applications with faster provisioning times. After all, that's where all the lifecycle babble makes sense ]
