data parallelism

data parallelism
параллелизм на уровне данных
организация и модель параллельных вычислений в многопроцессорной среде (см. SIMD), при которой одновременно обрабатываются сразу несколько элементов потока или массива данных (т. е. одна и та же операция выполняется над многими элементами структуры данных; пример - прибавление константы ко всем элементам массива или увеличение зарплаты всем сотрудникам со стажем десять и более лет). Широко применяется в графических процессорах.
Syn:
loop-level parallelism (по названию директивы в Фортране-90). Эта модель должна поддерживаться соответствующей архитектурой компьютера и/или компиляторами
