and here it is (only a few hours old):

Hardware and Software Architecture of The Machine

https://www.youtube.com/watch?v=S--Kgseuy0Q

Innovations in optical interconnect and storage technologies have
prompted HP to undertake a large-scale development effort called "The
Machine". This radical departure from traditional computer
architectures which we call 'Memory-Driven Computing', where large
scales of heterogenous computation can be brought to bear on a data
set which is accessed not over a traditional network or storage
system, but rather directly from the computational elements using
memory load/store instructions.

This presentation will describe the first implementation of this
architecture, both hardware and software. On the hardware side, this
will include:

b" Heterogenous computation node hardware
b" Memory interconnection fabric
b" Hundreds of terabytes of memory
b" Network interconnect
b" Top of Rack Management Server

The system software for The Machine is based on Debian GNU/Linux. The
presentation will focus on new and updated software elements while
mentioning some of the existing code that has been particularly useful:

b" Two-level storage allocation system
b" DAX changes needed to support large storage systems
b" Concurrent file system designed for large shared memories
b" Provisioning services
b" The Machine Environment Simulator (TMES)
