As of October, 2016 the total distance travelled for both
SPMD and AACVTE is 41.8 million miles in 6.4 million trips (ignition-on to off).
In computing,
SPMD is a technique employed to achieve parallelism, and it is the most common style of parallel programming.
The proposed parallel multicore system works in
SPMD fashion.
SPMD (Single Program Multiple Data), an approach that fits well in cases where the same algorithm runs against different sets of data.
Other major components at the Lee County site include Woodward
SPMD synchronizing systems, Thompson Technology generator breakers, SEL generator protection relays, Eaton Cutler-Hammer motor control centers, Silex silencers, radiators from Sutton Stromart and vibration isolators from Getzner.
The emergence and widespread adoption of the single program, multiple data (
SPMD) programming model and the standardization of parallel communications libraries in the 1990s have increased the use of parallel computers and offered the carrot of the very highest performance for scientific computing.
Although we have designed the interface having in view an
SPMD programming model on distributed-memory machines, we do not exclude different implementations, such as those based on a shared-memory model of computations.
The execution model is single program, multiple data (
SPMD), i.e., it supports a single user thread per processor, where each processor runs the same executable.
Traditionally,
SPMD extracts have been used for chemical analysis: to back-calculate the concentrations of compounds in water, to determine bioavailable organic chemicals, and to compare concentrations in
SPMDs to those in fish tissue, mussels, or other biota used for monitoring purposes (Huckins et al., 1990, 1996; Prest et al., 1995; Rohr et al., 1996).
This (Department of the Interior) research involves five areas: (1) continued development of the
SPMD technique for integrative sampling of hydrophobic chemicals; (2) evaluation of a deployment apparatus for use with
SPMD samplers; (3) continued development of an integrative sampling approach for toxic metals, and initiation of the development of an integrative sampler for volatile metals, specifically mercury vapor; (4) initiation of development of an integrative sampling approach for more hydrophilic chemicals; and (5) evaluation of extracts from standard
SPMDs deployed in the field, using a variety of bioassay procedures to determine the applicability of incorporating the
SPMD sampling technique into exposure assessment paradigms.
