IBM Plans Collaboration On Power Architecture
TheInternet writes "According to CNET News, IBM has made a series of announcements regarding the opening-up of the Power chip architecture. The story lacks technical details, but apparently, IBM is going to divulge more information about Power/PowerPC, and expects collaboration from the industry on the future of the chip. Nick Donofrio is quoted as saying: 'We will free electronics manufacturers from the limitations of proprietary microprocessor architectures', and Red Hat and Sony are two companies listed as taking part. Power5 was also shown, as was the Blue Gene/L supercomputer, using 32 500MHz processors to achieve 128 gigaflops."

Do you know why the road less traveled by is littered with the bones of the unwary?
This fits with IBM's vision for spreading the 970. There's two groups: "Pervasive" and "Deep." IBM uses "pervasive" to describe a wide range wired and wireless devices powered by the 970 chips, (i.e. p2p sharing of naked petrified natalie portman pictures). "Deep" computing describes IBM's high performance technical computing products, like Blue Gene.
Opening the architecture swings the door for pervasive market penetration, indeed.

128 Gigaflops? April's Fools!
(Hey, it's started already, just look at that pigeon story).

IBM has seen how well the Open Source/Community model has worked for Linux. Now they believe that it will benefit the deployment of POWER derived technology.
The details are a little sketchy at this point, but Wladawsky-Berger basically said this is of the same magnitude as the decision to embrace Linux.
I think I heard the word "community" in almost every other sentence. I truly believe IBM "gets it" and is moving forward in bold direction. The people I talked to afterward were credible and excited.
There will be a longer story on ClusterWorld tomorrow. (sign up for three free issues of the magazine as well)
I saw the small "Blue Gene" system. Very cool both performance wise and thermally (32 CPUs in a table top box). I also saw the new Power blade server. Nice.

As the POWER arcitecture is in reverse-ENDIAN order from the x86 arictecture, and to my knowledge, the x86 cannot switch order on the fly, I believe...
Such an emulator would necessarily be dog-slow compared to the real thing.
Keep in mind that this is only a constant cost, and only for reads and writes to things outside the processor (most commonly RAM). Once a value is in a register, you can leave it in the host endianness. Certainly there is a speed hit for every access, but you take a bigger hit in other things. For example: emulating the MMU, doing the math for every virtual memory access. Maybe you could leverage the host MMU for this in some way, but then good luck writing emulator code portable across architectures.
To handle this, Mac OS has generally included a "ROM" file which contained the part of Mac OS that had previously been stored on the ROM.
Mac OS and Mac OS X does do some checks before allowing itself to be installed on a machine, making sure it really is being installed on a Mac. I believe though that all it does ultimately is query OpenFirmware.
You are not alone. This is not normal. None of this is normal.
This highlights a fact that the previous poster missed. The architectures of the Pentium 4 and Itanium families are vastly different from the "x86 architecture" in the previous generations of chips. The x86 instruction set is there and the chip presents itself in a backwords compatible way to the system. The innards are vastly evolved, however. A similar analogy is the leap from the Pentium Pro/II/III architecture or K6 architecture to the Athlon architecture.
SPARC, MIPS, and PA-RISC have had relatively minor architecture changes over the same time period. The IBM Power chips have had much better evolutionary gains.
The SPARC is already an open architecture processor. It's been that way for years. Sun was the big player behind it, and certainly the best known, but the SPARC design is the closest thing there is to an "open source cpu." There's even a non-Sun organization (SPARC International) they spun off to act as a steward for the standard.
SPARC processors are made by Sun, Texas Instruments, Hitachi, and others. There's a history of all the chips made on their web site.
Dunno why they're too blind to see that this would be as good an idea for Java.
