    Microsoft just set the #2 TPC-C result in the non-clustered category using Windows Server 2003 and a 32-way Itanium 2 machine. They did this, of course, because Oracle publicly derides clustered results as not counting (and really setting up horizontally partitioned views across a huge federation of serves is not the easiest thing, and it's far from transparent for the database developer: You have to specifically design around it), so now there's a SQL Server 2000 result higher than any Oracle result.

    So there you have it: A 32-way machine that's actually useful (when available on 2003-06-30).

    NUMA, ok, that i understand.

    (Instead of one big shared memory pool it uses processors that each have their own pool, and can access other memory with a timing penalty)

    but what does "-preempt " have to do with this. what does this option do? Int unix always preemtive?

    Interesting that the 3 MS solutions (SQL server on Windows Server 2003) all also offer the best price/performance ratio too. Just something to think about.

    Would you have all been as interested in this story if you'd known:

    • It's been on KernelTrap for a *couple days* now
    • The machine in question is about 5 years old
    • Linux already has been booting on large-number-of-CPU machines for awhile. This story is about the CONFIG_PREEMPT subsubfeature.
    • This has very little to do with Linux's scalability. If I booted Linux 2.5.x on a bazillion CPU monster tomorrow, it wouldn't be a bazillion times faster than my single-CPU desktop system.

    *sigh*

    McDonalds makes hamburgers with the best price/performance. Just something to think about.

    Would be nice if /. mirrored the stories it links to. This way only news >1 day old is accessible :(
