RACEway Broadcast Support
The PowerPC compute node supports RACEway crossbar
broadcast capabilities for enhanced bandwidth utilization
when sending the same data to multiple nodes. This
hardware broadcast also reduces latency compared to
software-based schemes that emulate a hardware broadcast by
repetitively sending the same data in separate transfers.

hardware broadcast also reduces latency compared to
software-based schemes that emulate a hardware broadcast by
repetitively sending the same data in separate transfers.
As the initiator of a broadcast, either the PowerPC
processor or the DMA controller may use any of the broad-
cast or multicast modes provided by the RACEway crossbar.
As a receiver of broadcast data, the PowerPC CN has the
programmable option of accepting or ignoring the data.

Mercury's Scientific Algorithm Library (SAL) provides the
industry's easiest method of accessing the full power of the
AltiVec vector unit. The SAL contains hundreds of image and
signal processing functions that are optimized for AltiVec exe-
cution. These high-performance algorithms can also be
accessed through the industry-standard VSIPL interface using
Mercury's VSIPL-Lite signal processing library. For applica-
tions that require custom algorithms with demanding vector
processing requirements, Mercury's C compiler includes the
AltiVec C extensions that allow direct access to the AltiVec
vector unit.

For large-scale programming, the Parallel Acceleration System
(PAS™) supports data reorganization techniques for a wide
variety of efficient and scalable programming models, by
means of a high-level set of library calls. Scaling is achieved
by changing runtime variables rather than recompiling
the core code.

The TATL™ Trace Analysis Tool and Library from Mercury
is also available to assist during software development and
debugging. TATL is a minimally intrusive software logic
analyzer that allows developers to visualize multiprocessor
interactions. Using TATL, developers can spot bottlenecks,
such as contention for shared resources or load imbalances.

Commercial Environmental Specifications
Operating
temperature
0°C to 40°C up to an altitude of 10,000 feet
(inlet air temperature at motherboard's recommended minimum airflow)
Storage temperature
-40°C to 85°C
Relative humidity
10 to 90% (non-condensing)
As altitude increases, air density decreases, hence the cooling effect of a particular
CFM rating decreases. Many manufacturers specify altitude and temperature ranges
that are not simultaneous. Notice that the above operating temperature is specified
simultaneously with an altitude. Different limits can be achieved by trading among
altitude, temperature, performance, and airflow.
