Description
===========
The Compaq AlphaServer SC system is a distributed memory, parallel
supercomputer that scales up to 128 nodes to deliver incredible sustained
performance for large-scale applications. It is based on AlphaServer nodes
and an ultra-low-latency, high-bandwidth interconnect with an integrated
software package for management and application development. Compaq
AlphaServer SC System Software provides the utilities and libraries required
to operate and manage the AlphaServer SC. Optional Compaq AlphaServer SC
Development Software provides a full suite of tools for technical software
development.
Compaq AlphaServer SC systems include:
Compute Building Blocks (CBBs)
Interconnect Building Blocks (IBBs)
Management Building Block (MBB)
Storage Building Blocks (SBBs)
Compute Building Block
~~~~~~~~~~~~~~~~~~~~~~
A CBB is a rack that includes specially configured AlphaServer nodes. Each
node includes:
One or more Alpha 21264 (EV67 or EV68) CPUs
One or more AlphaServer SC Elan Adapter Cards
Tru64 UNIX
Interconnect Building Block
~~~~~~~~~~~~~~~~~~~~~~~~~~~
An IBB includes a multi-port switch using technology from Quadrics
Supercomputers World. Some IBB's also may contain management network and
console network components.
Management Building Block
~~~~~~~~~~~~~~~~~~~~~~~~~
An MBB consists of at least one Management Server, based on a DS20E, and may
also include management-network and console network management components
Storage Building Block
~~~~~~~~~~~~~~~~~~~~~~
An SBB includes a
Dual HSG80 RAID Controller
Required Storage Software
