Cray turns cluster crank with ScaleMP
New products for memory deprived datacenter set
http://www.theregister.co.uk/2013/10/02/cray_turns_cluster_crank/

Does your performance in the datacenter suffer because you don't have
enough memory to really get the job done? Do you have apps that don't
perform well on clusters, or don't parallelize at all? If this
describes you or a loved one, read on, because Cray thinks it has the
solution for you.

Cray, with partner ScaleMP, recently announced two new systems that aim
to cure your memory woes, in distinctly different ways.

Quantum computing gets recursive
Quis custodiet ipsos quanta?
http://www.theregister.co.uk/2013/10/01/quantum_computing_gets_recursive/

When a quantum computer can produce results that would take thousands
of years to produce out of a classical computer, an obvious question
arises: if you've given the wrong answer, how would you know? That's a
question to which University of Vienna boffins have turned their
attention to.

A computation involving a handful of qubits can be checked by a
classical computer, because it can iterate through the possible states
one-by-one. Some other quantum computations are also checkable in the
classical world: for example, if we produce a quantum computer with
enough power to factor very long cryptographic keys, the result would
be testable against the original message.

EMC snaps up ex Symantec veep to rule new HPC skunkworks
And hybrid cloud storage gateways - which EMC don't (yet?) do
http://www.theregister.co.uk/2013/09/27/emc_developing_hpc_storage/

EMC has recruited an ex-Symantec exec to lord it over its Emerging
Technology Products division. His product brief includes "hybrid Cloud
Gateways and High Performance Computing storage" which is fine ...
except EMC hasn't got any such products.

Chirantan "CJ" Desai will be the president of the newly-formed Emerging
Technology Products division and report to David Goulden, EMC's
president and COO. Goulden said: "CJ and this new division will bring
an elevated level of focus and scale for converting the full potential
of key emerging technologies into the most powerful solutions for our
customers."

StorNext gets revamp, Quantum claims 5x data throughput boost
Multi-threaded code, flash, metadata redesign and Infiniband support
http://www.theregister.co.uk/2013/09/23/stornext_gets_speedifying_kick/

Quantum has taken its StorNext file management system and updated it
from top to bottom, making it multi-core processor aware and more
scalable so it can handle five times more data than StorNext 4.

The company says workflows in the digital media and entertainment
business are becoming more complex, involving bigger files, greater
numbers of files, and larger team collaboration efforst. Its StorNext
software virtualises files and presents them for use irrespective of
whether they are stored on disk as files, on disk as objects or on tape
as files. The v5 update makes the whole package much snappier in use,
especially with random small file open operations.
