IBM Sequoia

20 petaflops. Is the processing speed of Sequoia, the next IBM supercomputer. Let me write it again: 20 petaflops, as you read. Not only is the world's fastest processor, but more than a list of the top 500 ... combined. 20,000 trillion operations per second. If the figure does not sound enough for you, IBM has provided some tangible ways to understand the future ability of its Sequoia:

If each of the 6700 million people use a calculator on the planet simultaneously 24 hours a day and 365 days a year (without going to the bathroom), take 320 years to do what they do in an hour Sequoia.

-20 Petaflops improve 50 times the ability to predict earthquakes, their effects can calculate building to building.

-20 Petaflops improve 40 times the capacity to monitor and predict the weather. Weather events could be calculated in an area of between 100 meters and 1 kilometer, instead of the estimated 10 kilometers available.

Sequoia will have 1.6 million cores with specific 45-nanometer chips still developing, and 1.6 petabytes of memory. You need 96 refrigerators and 280 square feet of space. The supercomputer will be impressive in the hands of the government of USA and I prefer not to think about what kind of real education is to be used

Researchers develop new super microscope

Researchers from IBM and Stanford University have created a new super-microscope, which in unprecedented structures may be: The device is still structures of 4 nanometers size three-dimensional dar.

The new technology promises unusual insights into the world of smaller and smaller. 

. The development of scientists based on the magnetic atomic force microscopy (Magnetic Resonance Force Microscopy, MRFM). Here, the magnetic field of a surface with the help of so-called Superconducting Quantum Interference units scanned. The procedure is similar to the well-known from the medical magnetic resonance imaging (MRI), however, is the resolution, according to the developer 100 million times higher.

IBM researchers have been working since the 90s at the MRFM. They succeeded, the sensitivity of the method once again to increase, so that it is extremely weak magnetic forces can be measured. Moreover, they have the procedure with a 3D image reconstruction methods.

First, they have used technology on a tobacco mosaic virus. It was a 3D view of the virus with a resolution of 4 nanometers create. That is 4 millionth of a millimeter. The virus attaches itself 18 nanometers in diameter. It was the first time that MRI for the observation of biological objects in the nanometer range has been used, so IBM.

MRI is an important tool in medicine, but for microscopy it is only suitable, said Dan Rugar, manager for Nanobereichstudien at IBM Research. Using the new technique will enable the internal structure of individual protein molecules and molecular complexes, something very important for understanding biological functions is. "This technology is the way we like viruses, bacteria, proteins and other biological elements, modify," says Mark Dean, a senior employee at IBM Research.
