Can IBM Beat Moore’s Law?
Big Blue Researchers have discovered a way to replace silicon semiconductors with carbon nanotube transistors and think that the development will push the industry past Moore’s law limits.
IBM said its researchers successfully shrunk transistor contacts in a way that didn’t limit the power of carbon nanotube devices. The chips could be smaller and faster and significantly surpass what’s possible with today’s silicon semiconductors.
The chips are made from carbon nanotubes consist of single atomic sheets of carbon in rolled-up tubes. This means that high-performance computers may well be capable of analysing big data faster, and battery life and the power of mobile and connected devices will be better. The advance may enable cloud-based data centres to provide more efficient services, IBM claims.
Moore’s law, which has for years governed the ability of the semiconductor industry to double the processing power of chips every 24 months is starting to reach the limits of physics when it comes to doubling the power of silicon chips. This could mean a slowing of significant computing performance boosts unless someone comes up with something fast.
IBM researchers claim to have proved that carbon nanotube transistors can work as switches at widths of 10,000 times thinner than a human hair, and less than half the size of the most advanced silicon technology.
The latest research has overcome “the other major hurdle in incorporating carbon nanotubes into semiconductor devices which could result in smaller chips with greater performance and lower power consumption,” IBM said.
Electrons found in carbon transistors move more efficiently than those that are silicon-based, even as the extremely thin bodies of carbon nanotubes offer more advantages at the atomic scale, IBM says.
The new research is jump-starting the move to a post-silicon future, and paying off on $3 billion in chip research and development investment IBM announced in 2014.

IBM Debuts New Mainframe
IBM has started shipping its all-new first z13 mainframe computer.
IBM has high hopes the upgraded model will generate solid sales based not only on usual customer patterns but its design focus aimed at helping them cope with expanding mobile usage, analysis of data, upgrading security and doing more “cloud” remote computing.
Mainframes are still a major part of the Systems and Technology Group at IBM, which overall contributed 10.8 percent of IBM’s total 2014 revenues of $92.8 billion. But the z Systems and their predecessors also generate revenue from software, leasing and maintenance and thus have a greater financial impact on IBM’s overall picture.
The new mainframe’s claim to fame is to use simultaneous multi-threading (SMT) to execute two instruction streams (or threads) on a processor core which delivers more throughput for Linux on z Systems and IBM z Integrated Information Processor (zIIP) eligible workloads.
There is also a single Instruction Multiple Data (SIMD), a vector processing model providing instruction level parallelism, to speed workloads such as analytics and mathematical modeling. All this means COBOL 5.2 and PL/I 4.5 exploit SIMD and improved floating point enhancements to deliver improved performance over and above that provided by the faster processor.
Its on chip cryptographic and compression coprocessors receive a performance boost improving both general processors and Integrated Facility for Linux (IFL) cryptographic performance and allowing compression of more data, helping tosave disk space and reducing data transfer time.
There is also a redesigned cache architecture, using eDRAM technology to provide twice as much second level cache and substantially more third and fourth level caches compared to the zEC12. Bigger and faster caches help to avoid untimely swaps and memory waits while maximisng the throughput of concurrent workload Tom McPherson, vice president of z System development, said that the new model was not just about microprocessors, though this model has many eight-core chips in it. Since everything has to be cooled by a combination of water and air, semiconductor scaling is slowing down, so “you have to get the value by optimizing.
The first real numbers on how the z13 is selling won’t be public until comments are made in IBM’s first-quarter report, due out in mid-April, when a little more than three weeks’ worth of billings will flow into it.
The company’s fiscal fortunes have sagged, with mixed reviews from both analysts and the blogosphere. Much of that revolves around IBM’s lag in cloud services. IBM is positioning the mainframe as a prime cloud server, one of the systems that is actually what cloud computing goes to and runs on.
