So the man is wrong b/c you don\'t like his nick name? Hannibal has a non-media (modern), and historical significance. But all Americans seem to know is based on television.

You keep making claims of deep understanding, and learned comprehension. OTOH you can\'t demonstrate it? You resort to an Ad Hominem (go look it up) attack on just one of my sources, yet you think it invalidates everything else? Now just who is delusional?

Have you read even one of them all the way through? Don\'t say you don\'t have time, you read \"Structured Computer Organization, Modern Operating Systems\" for fun. You\'re right, this is a waste of time. I agree with you.

It\'s you who doesn\'t understand RISC. You understand the old concept, but not how it\'s done today. (not even sure how much of that you really know well) You also don\'t really understand CISC, and a good example of CISC is Motorola\'s 68040. (you seem to think CISC is only Intel\'s) Just saying it doesn\'t make sense isn\'t an argument.

You don\'t bring evidence to back up your claims, but I do. You should read these:

http://arstechnica.com/cpu/4q99/risc-cisc/rvc-1.html
http://arstechnica.com/articles/paedia/cpu/g4vsk7.ars
http://arstechnica.com/articles/paedia/cpu/crusoe.ars

BTW, I do give you this. If VLIW is using instructions to schedule execution, then it\'s in hardware as one of the first of my links has said. (written into the compiler) OTOH, if VLIWis packing (not using) instructions together for scheduled execution, then it is indeed software. You have to understand something about piplineing to make any sense of that.

I think you\'re confused. Not only does RISC not have microcode, neither does anybody else who makes CISC based chips. The only CISC to use microcode is from Intel. All CISC implimentations use variable length instructions. One RISC characteristic is non-variable instruction length which speeds up execution. An example of VLIW implimentation is Transmeta\'s Crusoe. (w/o the codemorphing software which is NOT microcode)

url:http://www.transmeta.com/crusoe/vliw.html

I wasn\'t talking at all about EPIC anymore. RISC as a philosophy is no longer being used. Even the POWER5 while being called RISC is more like my argument for calling it \"Modern RISC\", and in that light moving scheduling into the instruction set is the next step on that path.

I was talking about VLIW, and from what I read scheduling was put into the instuction set. (hardware) Also the whole RISC philosophy was lets use multiplication as an example. In RISC you would have no instruction for multiply, instead the programmer would need to do multiple loops of adds to achieve this result. In CISC you would just use the multiply instruction. Now \"Modern RISC\" chips have evolved so far out of this that they are adding SIMD instructions. If you follow this out even further with OoO execution, adding instruction for scheduling is not hard to imagine. Therefore VLIW is RISC, but not in the old context since not even POWER5 is RISC in the old context.

BTW scheduling != hyperthreading && hyperthreading == subset of scheduling

Oh I see where your argument is going. Scheduling is usually done in software, like the new one we got in 2.6. VLIW is moving this on the hardware.

OTOH I would still consider VLIW RISC. Let me explain why. Part of what makes CISC is the instructions are of variable length. This is really all that is left that differentiates CISC from RISC architechtures. I want to add something to your iconography first.

RISC CISC VLIW

The new processors we call RISC are in fact more complicated than CISC every will be. So let\'s say we take the good points of both RISC & CISC, and we make a modern RISC (MRISC) w/ OoO execution, superscaler, DSP, SIMD, and other like technologies. They really fly in the face of the old RISC philosophy.

Now from that we add scheduling to the chip, and we now have where VLIW was going. Can you see my argument?

Keep in mind, the battles should be logged. Else if someone accomplishes the unimaginable, nobody believes them.

Thank you for adding to my knowledge, I didn\'t know that. Have any names, or links for me to read about it?

Some one should break this news to David K Every.

Read what I said, and what I did not.

(BTW, parting note: Allot of amd64 chips require registered RAM (even in 32bit) great for servers like mine , but bad for over all perfomance. Read with a careful eye on what metrics can influence your results. Chip model, what kind of RAM, remember PC333 was faster than PC400. People seem to have forgotten all of this when the Opteron was released)

Look it\'s been fun, really. I have even more fun arguing with a member of my team over the Pentium M. I\'m getting bored teaching you about semiconductor theory/design. I suggest you go read up on it some more.

Good luck, and have fun.

(IA64) You\'re right, it would have gone there in time. Like IBM\'s PowerPC line.

Your always free to believe what ever you want. You chose to ignore relavent commentary all along the way that would have betrayed your chosen view. Reality is perceptual.

\"... I was assuming we were...\"

As you said to me assumptions make you look foolish.

(performance) they added registers. Big performance boost for 64bit code. (32bit design) nope. Think of any amd64 (Athlon64 Opteron) running 32bit, as a old Athlon with a die shrink, and an integrated memory controller + Hyper Transport. Depends on what market you\'re in. Consumer hardware is not well suited to scientific applications. Alphas ruled there, as does Itanic today.

TMK IA64 is the very first VLIW processor. That is what made it cool. FYI it was never designed for consumer use.

(1) Sadly, it\'s why I use x86 as well. (2) Yes, you\'re wrong. ...again. (3) You miss the point x86 its self is dung. Even sparc (ugh) is better. Here\'s another reason to embrace only free software. It makes mass arch migrations trivial.

I almost bought a Cray vector machine from a recycler.

Runs like dogs. You open the gate, and they scream FREE as the run around the block pissing on poles! Also I said, runs like stalions.

I said nothing about the technology. My comment was on my chips here. I like how you slip your position around to avoid admitting your statments were obviously wrong. In the future if you\'re unclear about something plz ask.

Since you seem to want to know so bad. As for the technology. ANYTHING based on any successor to the i386 (i486 i586 i686 x86 x86_64 amd64 em64t ia32e) is pure dung. I don\'t care if it has gotten 64bits.

I liked IA64 (VLIW/EPIC) before it was implimented. It\'s still got some promise if they can ever realize it. (HP\'s book is a fun read) Alphas are the best, hands down. I like POWER (power optimised with enhanced risc) as a fine grained 64bit chip. (also the PPC970) Mips isn\'t bad either. I like high powered chips, and lots of GP registers.

\"They are not implementations of x86-64. There is amd64 and em64t/ia32e (Intel uses two names for unknown reasons). The arch formerly introduced as x86-64 in 1999 was renamed to amd64 in 2003. amd64 is not a superset of x86-64, it is the same arch. So it would be correct to state that em64t/ia32e is an implementation of amd64.\"

A quote from the Debian threads on amd64 arch.

in case you forgot: \"1) EMT64 and AMD64 are the same thing.\"

You\'re reaching. I said nothing about the technology. Which in this case is amd64 (x86_64 as gcc calls it), I did say that Intel\'s version doesn\'t perform as it should. You said as much too. Why are you still arguing?

\"The way that technology is implimented doesn\'t matter that much to how that technology performs.\"

That is so wrong, I don\'t know where to begin. Stick to writing code, and repeat after me. There is no place like home...

I still know, you don\'t know what you\'re talking about. I study pipelines for scientific computing. I know EM64T, and AMD64 are not the same. That is why it\'s called an \"implimentaion.\" (go look it up) Now who\'s assuming things. \"Obviously you don\'t\" I got a message for you on line 1, it\'s Mr. Pot and he says you\'re black Mr. Kettle.

You said it perfectly \"stuck on.\" Intel running heavy 64bit code is buggy. Oh wait, you just said as much. \"under load\" So which is it? Either my systems are setup wrong, or you just argeed with me?

1.) in your words, \"EMT64 is just the AMD64 technology stuck onto an existing Pentium4 chip.\" (BTW it\'s EM64T, and go look it up if you don\'t believe me \"Extended Memory 64-bit Technology\")

2.) in your words, \"I\'m using gentoo linux on both systems and I see little difference...only under load.\"

Now who looks very stupid? ...or arguing just to be arguing. Nothing I have said in any technical detail is wrong. Only the opposite can be said for you. The obvious conclusion here is that you need 4 64bit machines too, and then you\'ll know also what you\'re talking about? ;)

1) EMT64 and AMD64 are the same thing.
2) Your performance problems aren\'t the hardware\'s fault. Most likely PEBCAK :) 64-bit runs very fast for me.
3) And it isn\'t really Intel\'s fault if there is a design flaw, which there isn\'t, because AMD designed it and Intel copied it.


Don\'t speak unless you know what is being said. It just makes you look ignorant.

(1) AMD64 is AMD\'s implimentaion of their own amd64 (x86_64) architechture. EM64T is Inte\'s implimentaion of amd64. They are NOT the same thing.

AMD\'s runs like a stalion, and Intel\'s is crashy as hell. I own both, so I know. I\'m not a windows user, so I have no clue from that angle. I use 2.6 64bit on both, and I can show the differences.

(2) So yes, it is the EM64T\'s fault. I have a POWER4 too, and Linux also runs 64bit on it great too. We have a POWER5 on campus, and Linux runs great 64bit there too.

(3) Intel didn\'t copy crap! If they did it would run like an Opteron. Do you even have an EM64T to base your _opinion_? Yeah, I thought not. I have four 64bit machines home in my office.
