Just as a little FYI, here are come current numbers. 21164 Alpha @ 600MHz : 18.8 SpecInt, 29.0 SpecFP. 21264 Alpha @ 575MHz : 25.9 SpecInt, 40.9 SpecFP. Athlon @ 600MHz : 28.0 SpecInt, 22 SpecFP. PIII @ 600MHz : 24.0 SpecInt, 15.9 SpecFP. Those numbers are for BASE processors.. The original K7 Athlon, and the Katmai core PIII. For the Thunderbird I wasn't able to find any scores, and the other P III scores for the coppermine core aren't that much different from the Katmai core. The 21364 Alpha (not in production yet) is running at 1.2GHz, SpecInt 75.0, SpecFP 160.0 (estimated speeds.) That is probably the Alpha you're talking about, and it's a ways off in production. For timeframe purposes, it's pointless to compare it to any x86 machine available now, as by the time that is out, the Sledgehammer/Clawhammer (K8-64bit) processors, as well as the Willamette/Foster/Etc (IA-64 - P7) processors should be out. You have to always keep in mind floating-point vs. integer math as well.. other considerations such as price/performance etc are kind of moot I guess here, considering the absurd direction this email is taking.. >The lineup of Alphas currently produced range from a Microway workstation >for about $2000 to a Compaq cluster being developed for the U.S. Government >which will be the most powerful computer in the world. A Microway 21264 workstation (single processor) with a 667MHz processor and 128MB of memory is $8,500, not $2,000. A dual 500 21264 is $13,000. On that note, a 1GHz Athlon system from the same company is $3,300, with 512MB. So, maybe yes an Athlon system will have to be twice as fast MHz wise as an Alpha to be equally as fast in benchmarks, but who cares if it still costs only 1/3 as much? To equip the Alpha with memory is not cheap either, considering that it's nearly 3x as expensive as PC133 memory for the Athlon. Currently #1 system is the ASCI White at LLNL, 12 Trillion ops/sec, and is a cluster of 8,192 RS/6000 processors. Plans to extend this to the 30 Teraflop range are on track for next year, with plans for 100 Teraflop range for ~ 2003. www.llnl.gov/asci for more information. The machine you're talking about is ASCI Q, and as usual with your statements in this email.. does not exist yet. It is not going to exist until 2004 (scheduled), and is going to be roughly the same speed as ASCI White in 2003. http://www5.compaq.com/hpc/tsn/iss017/hptc_iss017_fa.html#1 >The best news is that most of the single-processor Alphas already are >equipped to run FreeBSD.

All in all, this was a really long and stupid email that had nothing to do with answering the simple question asked, which was just about IA-64 support in FreeBSD. I would say this, if Linux is going to support it, then it'll be a compiler option in gcc. If that is the case, then FreeBSD will be supporting it as well, unless something drastic happens in the near future. -- Proud owner of a 600MHz Athlon, 512MB of memory, all Ultra/160 SCSI, A 19" monitor, a GeForce256, and other misc options that all together still cost me about 1/4 what a similarly equipped Alpha would have cost. -- -------signature file------- PGP Key Fingerprint: 446B 7718 B219 9F1E 43DD 8E4A 6BE9 D739 CCC5 7FD7 "I don't think [Linux] will be very successful in the long run."
