Bill Gates: We can lower the world’s population with vaccines
At a time when anthropogenic global warming (AGW) is becoming broadly recognized as a politically driven, pseudo-scientific power-grab, Microsoft billionaire Bill Gates recently “unvielded his vision” of global catastrophe unless net man-made carbon emissions are reduced to zero. The video of his peculiar, ill-timed, February TED2010 talk is here. Gates also delivered a very odd [...]
8.8 Chilean earthquake predicted two days ago
Two days ago a poster on the popular Godlike Productions message board predicted large quakes might occur on February 27. At 3:45 AM today, a magnitude 8.8 earthquake struck Chile, the fifth or sixth strongest quake of the last 100 years. The poster, “ZOSIME,” based his prediction on the impact of a coronal mass ejection (CME) [...]

Apple iPad: It might be worse than you think
Apple introduced its greatly anticipated tablet computer, the iPad, yesterday. It was impossible for the product to meet the unbelievable hype surrounding the computer’s debut, but even taking this into account, the reaction to the device, which will not ship for months, has been mostly negative. Critics point out the iPad’s lack of multitasking, the low [...]

Essential Free Windows Programs
Although I use Ubuntu more and more, I still have to spend a large portion of my day working in Windows, primarily because of my job. Gaming and navigation software are other reasons why I boot up Windows. Whenever I load a box with Windows, I usually install the following programs. OpenOffice: OpenOffice 3 has [...]
Occult symbolism in 2012 Chevrolet Silverado Super Bowl commercial
Chevrolet has uploaded to YouTube a 2012 Super Bowl advertisement for its popular Silverado line of pickup trucks. Based in a post-apocalyptic world foretold by the Maya, the ad shows a surviving Chevy Silverado emerging from the rubble and driving past a series of end-of-the-world disaster movie cliches while Barry Manilow’s Looks Like We Made [...]
Strange Circular Object Sighted at the Bottom of the Baltic
Using sonar, a group of Swedish treasure hunters have discovered an odd 60 meter (200 foot) disc-shaped object on the bottom of the Baltic Sea adjacent to 400 meter (1,300 foot) “drag marks.” Referred to as an underwater “UFO” by the discoverer, the circular feature does not appear to be natural.
The talented Blue Grass group The Cleverlys covers the Bangles hit Walk Like an Egyptian and the result is comedic genius that sounds great. The spastic, twitchy, hilarious and gifted drummer is “Digger Jr. Jr.” who has been missing from the band for nearly two years. Whatever happened to him, The Cleverlys need to bring [...]
Recipe for a Revolution
Comet Lovejoy plunges towards Sun
In what could become the most spectacular solar event of an already eventful year, Comet Lovejoy (C/2011 W3) is racing towards solar doom today. With a coma that appears to be larger than Jupiter and with a tail stretching for tens of millions of miles, Comet Lovejoy is the first sungrazing comet observed directly from [...]
Deposed Libyan leader Moammar Gadhafi was reportedly killed today. While members of the United States Government celebrate his killing, this video depicts a very different man and a very different Libya than the demonized images seen in mainstream media over the last year. The simple fact is that we do not have to struggle and [...]

Spectacular comet impact triggers coronal mass ejection
The largest cometary impact of the sun that I have ever witnessed occurred this weekend triggering a significant coronal mass ejection (CME). The animated GIF below shows the event. The coma of the comet was bigger than the earth (although the nucleus was certainly much less massive) and its tail stretched for several million miles. [...]
Part 2: The Georgia Guidestones, The Mahdi, World War III and Comet Elenin
This is the second installment of a series of informal blog posts about these eminently important topics. You can read the first post here. From all available scientific information, Comet Elenin is nothing special. In fact, it looks to be a boring, barely observable fizzy little conglomeration of rock and ice hurtling quickly through the [...]
The Georgia Guidestones, The Mahdi, World War III and Comet Elenin
For several months I have needed to write an important article following up on my Georgia Guidestones research. A good introduction to that research is here. However, my business is keeping me very busy and has made it impossible for me to spare enough time to write a proper article. Since so little time is [...]
The memory system bus speed may not be important to CoreMark’s code once loaded into a core’s cache, but communication between multiple cores still operates on that bus, doesn’t it? Wouldn’t that be a factor? Or are shared, on-die cores operating at non-memory-bus speeds?
Hi, Rick. If it’s an SMP system, then the cores communicate and coordinate over the bus, but multi-core chips do most of this through their integrated caches which usually operate at core speed.
Van, that’s interesting. I’ve always thought the same-die multi-core CPUs still communicated over the system bus (and the MOESI protocol), they just did it on-die, with the cache being its own component that’s sort of “in the loop,” as it were, sending data to the cores as it’s requested and present. I didn’t realize there were different integrated buses internally and externally.
How does that work with power planes and variable-clocked cores? The bus between cores must be maintained at a constant voltage and clock speed then, separate from the thing it’s communicating with, and regardless of the other core’s compute clock speed, right? Or in the alternative, when a particular core goes high / low voltage, there must be circuitry at every other core which auto-adjusts up/down to transmit to the other cores?
Well, you’re right for some of the very primitive “dual-core” implementations like the P4-D and the “dual-core” Atoms. In those cases, you really have an SMP system on a package where two discrete dice are tied together over a shared bus. The 65-nm “dual-core” VIA Nano (CNB) prototype at the last Computex was implemented similarly, but it apparently will not be released. Instead, Centaur plans a true dual-core design for the 45-nm shrink. I believe that design will be very similar to a Core2 Duo with a large, shared L2. The last I heard, Glenn, Al and Rodney were targeting C2D-level IPC as well, and they were confident that they could reach it.
I’m not an expert on maintaining cache-coherency in true multi-core environments, particularly with integrated memory controllers like you see with AMD, ARM and newer Intel processors — in those cases, there is no external FSB. I believe they all communicate with the outside world using high-speed serial buses. I think Centaur planned to use PCIe for this.
Power management with modern CPUs has become extremely complicated. My experience has been with single-core chips. My assumption has been that multicore chips need separate power planes if each core is going to be turned off individually. Regarding P-States, I’m sure each core has its own PLL triggered by the same master B-Clock and the only way for voltages to be different for each core is if they each had their own power plane.
One issue that has been problematic over the years is the timestamp counter (TSC). Microsoft issued a recommendation many years ago that the TSC should be incremented at a constant rate regardless of the true CPU frequency; this would make it easy to keep the TSCs in sync between cores. However, it hasn’t worked that way until recently and it was a headache for benchmark developers who use the TSC as a high resolution timer.
Van, definitely makes sense. I remember reading about the RDTSC issue as well. I also remember Intel working on their 40-core Terascale 2 CPU, which contained an undisclosed x86 core (though I believe it was based on the modern Pentium-like in-order version seen in Larrabee), which had a 6-way proprietary bus architectures for massive data migration per core per clock.
Terascale 2′s die cores were arranged in a tile pattern with each core having north/south/east/west communication in 4-ways, and then 1-way dedicated back-and-forth to main memory and 1-way dedicated back-and-forth to non-adjacent cores. The total aggregate bandwidth on that CPU was theoretically unreal (don’t remember exact figures, but I believe around 256 Terabits/s (320 GB/s) on around 100 watts).
When I interviewed Jerry Bautista in 2007, he was extremely excited about Terascale 2. I even managed to arrange a meeting between him and another person I had interviewed previously, Dr. Ioannis A. Kakadiaris of the Texas Learning & Computation Center at the University of Houston. Dr. Kakadiaris hoped to utilize the amazing compute potential of Terascale 2 for 3D medical scanning systems he was developing, that had just a volume of data that it was not feasible to conduct in real-time. He was hoping to develop “agent algorithms” which would sift through the 3D medical scans, looking for problems automatically, without a doctor having to eyeball the scans to see the tumors, etc. It was a fascinating medical technology, and an equally fascinating application of the hardware side to solve it.
