Slashback: Grids, Netscape, AMD

Slashback tonight (is this number 200 already?) brings a few updates and amplifications on grid computing and AMD's plans vis a vis Intel. Also, it seems that some of the best features of Mozilla have finally infiltrated the world of Netscape. Read on the for the details.

And Campbell's puts glass marbles in their soup pictures. Roland Piquepaille writes "We saw several grid computing announcements in the last couple of days.Of course, Gateway stole the show. In 'Gateway makes store PCs work overtime,' you can read that 'Gateway's network of 8,000 PCs can deliver 14 teraflops.' This is plain wrong. You all know that this number of 14 teraflops is meaningless. It's just the addition of the peak speed of all the PCs -- never reached anyway on individual PCs. You need specialized software to work efficiently with a grid. And two companies are releasing new products to power grids. Avaki rolled out what it believes is the first Java-based data grid software for enterprise-class IT environments. Kontiki, for its part, on Monday released a grid server that brings its content delivery system into the server realm, whereas previously it was only available for PCs. Check this column for a summary, or this article for more details."

Why aren't those things called 'stick-up' ads, anyhow? Internet Ninja writes "Netscape today released version 7.01 of Netscape based on Mozilla 1.0.2. Back in is popup blocking which they got a lashing for in 7.0 as well as tabs as home pages just like Mozilla. Release notes here and there's a couple articles on Netscape devedge which may be of interest to developers."

And they will continue to have produced my Athlon, too. schnoz writes "And you thought AMD was quitting the PC chip market? Then check out this article on Business Week. Not only are they releasing new chips and plan to continue to do so, they're also still very active research wise, working on new transistor making techniques such as the double gate design as well as metal-rather-than-silicon design. Keep going at it AMD!!"

Re:Netscape 7.01 blocks popups. Next will be IE?

[bmwm3nut]

i sure hope not. i don't want the average joe to be blocking pop-ups. once pop-up blocking becomes mainstream then the advertisers are going to switch to a format that is harder to deal with. i like using mozilla and blocking pop-ups, but if the advertisers change their format to a harder to block type, then i'll be seeing ads again.

well if you want the whole story

you are right; game consoles do use RDRAM. But in the end, RDRAM is not killed because it's bad technology, but because othere stuff.

first on the tech. (REALLY quick brief)

1) RDRAM has a faster interface (duh)
2) and it has a much more narrow bus
3) but to make chips drive at such a high frequency ON THE CIRCUIT BOARD, the bus interface for RDRAM is totally wacky

explanation: RDRAM is serially connected, *kinda* like... SCSI, or COAX ethernet back in the days. and it's heavily terminated. and because the signal goes so damn fast (remember, circuit board made of FR4 here - not cache->CPU interconnects), the routing of the signal traces, while sparse (something they tout - and it's true, DDR has like 2-4 time the wire density as RDRAM on the board), has very small tolerance for length difference. furthermore because the high speed, the chips must have a very strict output impedance (which is why mem-makers got shitty yields at the beginning and the RDRAM price were so high).

performance wise / practically speaking, since it's the signal routing / RIMM detection and delay adjustment (remember no trace length differences etc) that's difficult and causes trouble - in game consoles where you will never add memory, RDRAM is actually better (easier to work with / better performance - better perf because you don't incur additional delays in the trace by adding more modules, everything is fixed). Same time on PCs, when you do it right, RDRAM still offers better bandwidth than DDR; DDR-2 i am not so sure, but that won't be in massive production for a while so don't wait for it yet. depending on architecture (P4 is, have to say, on the side of "optimized for RDRAM"), you would get better performance out of RDRAM for a little while longer.

now the non-tech side:

RAMBUS charges royalty. 2% i think? now - memory business is not high-margin business (or else there won't be only like 4-5 memory makers left!), so when 2% is actually like 40% from the margin - if you can do away with RAMBUS (even at a performance hit), it would enable you to survive, or make more money - depending on the company.

so... the moral of the story? RDRAM is not bad technology (i.e. has its uses - like in consoles), but it's not GREAT technology, and certainly not good enough to warrent the margin cut and the headaches in engineering (output impedence - and these days they are going to 32/64 bit so the sparse signal lines is less and less of a advertisable benefit). But I expect that it will maintain it's little niche and won't just die off suddenly one day. i mean, heck - even if they only supplied for the game consoles, (especially with the large chunck of change intel gave to RAMBUS) they can survive for quite a while. RAMBUS as a company I think will eventually fail if they continue this path of IP-only, though - for other reasons. but this is getting long already.
