Hi all, I'm shopping for a quad server for a heavy number-crunching application. What I need is:
- good floating point performance - good memory bandwidth (we need/want to move ~6GB around at ~200MB/s) Although some sort of AlphaServer would probably be a good bet for us, it looks like our budget can accommodate either a quad Xeon or quad Itanium server (e.g. Dell 6450 or Dell 7150). With that choice in mind, I would like to solicit input on some questions: - According to spec.org, the Itanium is just about tops in floating point performance. Is that also supported by real-world applications? - How good is the memory throughput? For example, I know that the 8-way Xeons are memory I/O dogs due to the system architecture. Getting data to/from the CPU's is a real issue for our application. - 1st generation Intel chips always seems to come up short compared to their hype. Does the Itanium suffer from any inherent problems? - Is Red Hat IA64 as stable as the i386 version? Is there any reason to fear it being abandoned like the Sparc version? Any input from the list would really help me make this decision.
