Today we host an interview with Christophe de Dinechin, Software Architect in HP-UX (Software business unit, Infrastructure Solutions). Most of you already know HP-UX, the leading "traditional" UNIX today feature-wise (second only to Solaris in Unix market-share, mostly competing with AIX). With Christophe we discuss HP-UX's competition, the other... 5 OSes HP supports with its various products, the Itanium platform and more.

Well, no. Clustered vs. non-clustered results on the TPC-C test are not comparable because TPC-C is so darn easy to partition. For example, a database running TPC-C on a NUMA cluster of 32 two-way systems would kick in the teeth of a real 64 processor box, ceteris paribus. That stack of dual processor systems is certainly cheaper, too. But the 64-way system would crush the cluster on anything that couldn't be partitioned the way TPC-C can.

PS Any chance that the PRE tag could be added to the "allowed HTML" list? Can't think of any quick way to explain the concepts without pretty ASCII pictures. :0)
