New "Memristor" from HP

Saturday, June 12th, 2010

The New York Times reports that a team of Hewlett-Packard scientists have designed an electrical resistor with memory properties called "memristor." The technology is simpler than existing transistors, and do not require a constant electrical current to retain information. Originally revealed in the science journal Nature Wednesday, the team believes that its new memory technology will lead to powerful yet extremely small computers that imitate biological functions.

The article covers different applications of memristor including to possibility of creating dense memory chips that use less power than DRAM memory chips of today. But the big bonus prize is that HP’s technology can store and retrieve values outside the standard 1′s and 0′s–a vast array of intermediate values as the NYT claims–allowing the resistors to function like biological synapses.

Intel Demos System Based on 48-Core Processor

Saturday, June 12th, 2010

Last month Intel announced that it was shipping systems with its experimental 48-core processor. Now we get to see what a system with the radical chip looks like.

X-bit labs caught the supercomputer on chip (SCC) system on demonstration in Europe, which runs on an experimental "Copper Ridge" motherboard with integrated I/O and graphics and eight DIMM slots. There’s no SATA ports, instead an Intel USB flash disk is used for storage.

According to the report, the SCC contains 24 tiles with two x86 cores per tile, each of which has its own L2 cache and can run a separate OS and software stack and act like an individual compute node that communicates with other compute nodes over a packet-based network. The SCC also has four integrated DDR3 memory controllers.
