Larrabee never even made it to market; the chip was instead repurposed as Knights Ferry, a prototype MIC (Many Integrated Core) architecture.
At the moment, the current Knights Corner hardware characteristics appear to be "under evaluation," which explains why we have seen the evolution from the 32-core Knights Ferry design.
Having used Knights Ferry hardware, it is clear that synchronization upon a single memory location can dramatically slow program execution, because it will cause the cores to serialize when accessing one cache or memory location.
While Intel is not releasing any information about the power efficiency of the Knights Corner chips, Colfax did release information about an SGEMM benchmark running on an older 32-core Knights Ferry board that utilized eight cards in a workstation and achieved 7.4 TF/s.
Intel has provided Altair early access to the Intel MIC software development platform, codenamed "Knights Ferry," and early versions of the software stack.
"The 'Knights Ferry' program allows us to gain valuable insight from our partners and ensures that Intel[R] MIC architecture, the latest breakthrough in high performance computing, has full software support for a variety of usage models when it launches," said Paresh Pattani, Intel's director of HPC and Many Core computing.
(A development version known as Knights Ferry is already available.) The MIC architecture shares the memory model and instruction set with existing Xeon processors, along with enhanced floating point.
A Xeon server with eight Knights Ferry chips can deliver 7.4 teraflops of performance, said John Hengeveld, director of marketing for Intel's Data Center Group.
Top server vendors Hewlett-Packard, Dell and IBM will also show systems using Knights Ferry chips at ISC.
In 1849, Knights Ferry was a crossingarea to the gold fields and home to the first ferry across the Stanislaus.
Most of the oldest structures are on or justuphill from Main Street (Sonora Road), which runs the 1/2 mile between Knights Ferry Resort and the covered bridge.
It didn't work, so Intel decided to re-spin it as a manycore architecture dubbed Knights Ferry.
