Focused heat removal where you need it.
Although I'd presume the particles are encapsulated to prevent settling and forming a lump in the low points of the systems.
Personally I've always wondered about about a sort of "liquid crankshaft" linking the cylinders on an internal combustion engine. The system acting as a regular hydraulic system with 1 way valves to keep the pistons cycling, then turning on the magnetism to shut down part of the engine (any part of the engine) and let the rest of the cylinders run.
Handy (I though) for any big engine that runs a lot in traffic, where a lot of the time is spent on ideal.
Thumbs up for bringing this out.
"Another senator was a little more honest in his appraisal. Senator Mark Warner of Virginia observed that Bitcoin could "dramatically transform" the role of central banks."
Didn't he also admit it took him 2 months to get his head round it?
A politician who admits stuff is "hard."
"Mixed feelings on this. The disgusting things that are being blocked in this example is obviously good, but cant help but feel this is just the tip of the iceberg when it comes to deciding what people see and don’t see online."
That's why the TOTC routine works so well.
Whenever someone talks about "Saving the children" you better ask "For whom?"
Very fast compilers (or more likely) cross compilers.
Handy if you're going to build compilers for all those interpreted languages currently using the shared runtime. that MS encourage everyone else (but themselves) to use.
Pretty much what I thought.
That said fine state automata can be powerful abstractions.
But it does sound like the "pixel planes" PE's embedded in memory of Chapel Hill NC in the mid 80's.
I actually think using an interface common to memory modules is a pretty good idea.
That spells MEMS actuator technology to me.
I'm thinking of an on chip container will etched pillars and sacrificial supports to create the "pellets" in the chamber and the use of flexures to maintain the activating fluid within the chamber. With the etched volume being less than 2/3 of the volume of the chamber as the Silicon is exposed it expands and exerts pressure on the membrane used to transmit force, effectively the "cylinder head."
The attractive feature of this is that (potentially) high pressure could be excerted without needing to transmit high pressures by some sort of micro hydraulic system (which AFAIK does not scale down well).
"What party politics? I'm Canadian. I have no "party" within the US. They're all bloody nuts, but some have recently been demonstrably more nuts than others."
Indeed.
Time was you only had to know about the religious nut jobs.
Now you have the Swivel Eyed Loons of the "Tea Party," with their Trotsky style infiltration tactics. I'm sure US readers can identify other types for whom their prime "candidacy" should be that of a room with mattress wallpaper.
I think it was actually Richard Condon in The Manchurian Candidate (which is actually more a political satire and black comedy than a thriller) who noted politics is about who you get to do it to you, about 30 years before Douglas Adams.
So wrap the crystals in a cooling jacket.
Simple answer is a closed loop with anti freeze, being good down to a few 10s of degrees below C.
Beyond that you're into LO2, LN2, LH2 and LHe, with progressive levels of nastiness.
Thumbs up for the enormous enlargement but the computing procedure sounds more like the days of analog computing, when programmers re-configured the wiring between op-amp modules to change what was being computed. Keep in mind that tech was how the early flight simulators could give real time response to control inputs when the digital hardware of the day would take seconds to solve the equivalent equations and drive the actuators.
One would be a "de-bloater" run of your favorite language system, like the old "development" (fast compile) and "production" (highly optimizing) compilers.
This would a) pull a copy of all needed library functions b)pack them into a minimal set of pages c)Renames all variables so that they could be found in the symbol table as quickly as possible (IE Long enough to be unique to the run time system but not excessively large).
Of course you could develop compilers for all those interpreted languages.
Two is much harder.
The core of parallel programs seems to mathematics. The true roadblock seems to be the core of that code where the results of parallel streams are combined
So you need to design a number system that allows numeric operations without carry between digits.
With no carry to worry about individual digits can be processed at maximum speed from different processors, without worrying that the last (slowest) processing elements result will kick over every other digit of the current partial result.
How you incorporate that into a FORTRAN/C/C++ or other compiler will be very difficult.
But until you do the true promise of parallel processing will not be fulfilled.
BTW for anyone wanting to take a crack at the new hotness and become the Intel of the mid 21st century.
1) The closer to room temperature the better. You're dead if you need an LHe cooler.
2)It has to be programmable in a language a substantial number of people already use. Anyone have any idea how to program a quantum computer?
3)Your new design technology will need a notation to describe your "gates" or whatever you're calling them. Ideally you'll also have a way so that EDA software can use them.
4) Transistors have a fan out and fan in of (typically) 10. Human neurons can go 1:10 000. Bigger is better, but at least matching a transistor is a start.
Personally I like optical systems, but the challenge is true optical transistor behavior IE light/light switching.
"2) At present the lower bound on latency is set at the speed of light (C). So far we haven't found a way to increase the value of C."
Actually a lot of the time stuff propagates at about 1/3 c on PCB tracks and normal wiring however by impedance matching the lines (which can be done on PCBs as well) you get close to c transmission speeds, and (AFAIK) that can be done at the chip level as well.
That the share will be being sold by the company (so the funds go into the company bank account, not the senior staffs).
Thumbs up for this but it will take a very strong management to remain independent and not get bought out by some American foreign conglomerate.
This could be one of the 21st century success stories of materials processing, in the way that say Gore Tex was in the 80's.
AFAIK the only way that happens is if Mars is solid all the way through.
OTOH that would also seem to kill any sort of magnetic field (no molten nickel iron to generate a current), but Mars does have one (although IIRC it's not very strong).
So a Mars with no volcanoes ever would be a very surprising beast.
thumbs up for the analysis.
"Anybody who says renewables are the future
- hankers after the Dark ages
- wants to kill most of the human race (not an unreasonable position given how crowded with green idiots its getting)
- is lying
- has an interest in a renewables company"
Or maybe has a very narrow definition of what "renewable" means.
Can include
Anerobic digestion
Micro hydro
Geothermal from every oil well that has ever been dug and is no longer producing.
Space solar.
But these options are a bit complex and "industrial" for the wigwam living Jades.
And of course if you want large scale compact, no CO2 then logic --> nuclear systems.
"This just goes to show how ignorant your average person is about CO2. Whether you believe in global warming or not - the third world cranks out *a miniscule fraction* of anthropogenic CO2 - because they don't have any bloody industry. "
That depends where you put India and China.
I'd say both countries have quite a few people with "3rd world" living standards.
I doubt that.
Historically only certain kinds of "high neutron flux" reactor have been used to make the fuel for NASA's TEG's but I think people are realizing that the US has a lot of commercial reactors that could take a specially loaded fuel pin or two. Individually their output would be small but with 10-20 of them it adds up to a tidy haul.
That said this technology did give about 28% output over the 7% currently.
"I predict that the only productive output of all the recently announced rich-guys-mining-asteroids projects will be U-235, enabling an end run around the pussies who won't let us put more reactors up on rockets."
NASA does not put nuclear reactors on rockets.
The US has not flown a nuclear reactor in space since 1965.
Very large quantity of ice + very large quantity of molten rock spewing over it --> trouble.
This is not a problem now but for those with a worst case planning turn of mind it's definitely not a happy discovery.
However thumbs up to the team for field work and finding this out before a whole bunch of people wake up one morning and find they need a boat.
I guess up to now most HPC systems have been by assuming that identical hardare == identical performance.
A reasonable idea.
But wrong.
Except I can't help think that things like Tivoli and what was CA Unicenter were meant to have tools like that a decade ago.
