Howdie ladies (and gentlemen), I just got a call from a guy who's running a "highly optimized math app in Java" on xeon (I didn't know JVM's had strong VFPUs...) and just got himself an Itanium to get better performance. He was very surprised to get 25% of the speed on the new platform and wondered if he should switch from Windows64 to Linux.
I told him that to the best of my knowledge, for pure math apps, Itanium indeed wins over x86, but the JVM sticks to a standard and does not offer the app access to those incredible speedups. I suggested that if porting the entire app to C++ is not an option, he could consider using gcj to compile the java to native, but even then I doubt he will be able to tap into the legendary FPU powers of the Itanium. So... did I mislead the guy or did I make sense? Itanium and JVM implementations are not my specialties, but from what I know of them, I grok that I painted for him the right picture more or less. Thanks in advance, Ira. -- The Hobbit Ira Abramov http://ira.abramov.org/email/ ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
