x86 on IA-64 [Dec. 27th, 2004|10:54 am]
Brad Fitzpatrick
I'm running a CPU-heavy app on an Itanium2 box now. For a while I couldn't get it to compile IA-64 so I was using the x86 binary.... 100% CPU. Got it to rebuild and it's now at 80% CPU and running 4x faster.

Intel really dropped the ball on the IA-64. Sure, the x86 has a ton of problems, but the existing software base is so large that it makes sense to make it as backward-compatible as possible. I think they had a similar problem with the Pentium Pro, which wouldn't run 16-bit software (like parts of Windows 9x) without major slowdowns.

IA-64 works great. I don't give a fuck about binary compatability. MySQL, Linux, etc run awesome.

The bug compiling this latest app was a real bug... fixed it and it compiled fine.
