Are they also suing scientific journals?

The word "Hobbit" is used to describe small, smart hominids found on the island of Flores in Indonesia in the scientific literature. See e.g. this pdf. Do they want to sue Nature, or Elsevier?

The situation is a bit different from that of planets, as the notion of dwarf planet was introduced to cover cases like Pluto and the larger Kuiper-belt objects. The notion of a dwarf galaxy has been around much longer. Proper definitions help to avoid confusion.

Re: "Study shows soap operas trigger aggression in women"

" personally think that watching that shit would wind anybody up, male or female. I only have to hear the theme tune from A Certain Famous Soap to feel my blood pressure rising."

Absolutely! My wife frequently wonders why I leave the room when certain shows are on TV (not just soaps, "talent" (word used without prejudice) shows have an even more pronounced effect). I tend not to say I am looking for more fun things to do, like stapling my ears to a wall, or putting my hand in a meat grinder. Somehow, remarks like that do not go down well.

Pity I did not hear this yesterday.

I was accosted by evangelical Christians yesterday evening and was asked what I believed in. I pointed to Venus, Jupiter, and Mars in the sky stating that my Goddess of Love, Father of Gods, and God of war were all now visible in the sky, so who was I to doubt. They were genuinely shocked.

On the other hand, if I started out about the FSM they would probably know immediately I was pulling their leg (which I was of course), so suggesting belief in ancient gods is probably the better ploy.

Cool!

I will test the 64 core 512GB single box (4U rack server) we are getting shortly (for processing large astronomical and remote sensing images rapidly). I will compare the cents per MFLOP/s to the figures here. We already know it will kick the backside of the 32 processor Cray SV1e we used to have performance wise, at less that 1% of the cost. I am really curious what the figures will be. Linpack has its limits of course, but it is still nice to know where you stand, even roughly.

Regarding blacklisting, given that your bank knows your date of birth, surely they could forbid you to use a number derived from that date? That would not prevent you from using your wife's, or kids birthday, but those are not printed on your ID, as a rule, so at least some security is added.

Re: Re: I could use such power

Many image processing tools are easily broken up into small loads. The tools we develop are so-called connected filters in which data from all parts of the image may influence all other parts. Often you want to avoid this, but e.g. for analysis of complete road networks, you cannot predict which parts need to communicate with which other parts. To cut communication overhead down you need comparatively coarse grained parallellism.

We have been able to device a scheme (which we are now implementing) which cuts down local memory requirements from O(N) to O(N/Np + sqrt(N)), with N the number of pixels and Np the number of processor nodes. Normally you just require O(N/Np) per node. Communication overhead can be dropped from O(N) to O(sqrt(N) log(N)). This has moved the problem from the impossible to the "possible, but you need a coarse-grained cluster."

Of course, the first (shared memory) parallel algorithm for this filters dates from 2008, so we still have much to learn. Other problems in science can also require global interaction between particles (gravity has infinite reach). A lot of work is done cutting communication down, but this is often at the expense of accuracy.

I could use such power

We are looking at terapixel scale image processing. One aim is compute the entire aerial photography data set of the Haiti earthquake for damage assessment. We aim to do this in a few hours. This can still be done at the multi gigaflop rates provided by decent size clusters. For the 2004 tsunami, we would need orders of magnitude more compute power to handle all measurements required (we are talking petapixel range). These are computations that cannot possibly wait. Though exaflop processing might not be needed yet, as image resolution increases, so do the data rates. Compute power will have to keep up. Real-time emergency response requires real-time processing of vast amounts of data. The size of each compute node of the EC2 and similar cloud systems is far too small for our purposes (we need to have at least 32 cores (preferably 64) cores per node and between 128 GB and 1 TB of RAM per node).

So, yes, I can see real-world, life and death applications for these kinds of compute powers. Other applications include large scale scientific simulations (think evolution of galaxies, or the cosmic web, but also earthquakes, ocean currents, or even the blood flow through a sizeable chunk of the vascular system).

Tiny transistor stays where it's put

Michael H.F. Wilkinson

-196 C is cold, but

it is "merely" liquid nitrogen (LiN) level. Not everyday, but not nearly as impractical as previous devices requiring liquid helium (LiHe) temperatures. Think of the Josephson switch, which was hailed as a breakthrough in high performance computing once. LiHe cooling requirements.

If we can build qubit devices based on this, the potential gains might outstrip the cost of LiN cooling.

Users might not care, but what do they know?

If all OSS products were withdrawn or crippled in one fell swoop, how much of the internet would be left standing? Users do not care about the fact that Apache is OSS, or that their home wifi router runs Linux, but unplug all OSS products from the net, and the wails of anguish would be deafening. Much of open OSS (or software in general) is not sexy. It just sits in the background doing some vital job. That means people only begin to care when something fails.

Chip boffins demo 22-nanometer maskless wafer-baking

Michael H.F. Wilkinson
Silver badge
Thumb Up

Good point!

Small runs become much more interesting this way. Ultimately, one might envisage chip making to be commoditized like 3D printing is becoming a commodity. One off parts are becoming affordable (see LOHAN). Imagine designing your own ASIC chip from scratch rather than going the FPGA route. Design a schematic, send it off, have a wafer-full made, mounted and sent to you.

Far fetched now, but maybe some day.

What do you mean "a man can dream"? A man should dream!
