# Отчет по лабораторной работе №6
|
||||
|
||||
Выполнила студентка гр. ИСЭбд-41 Воронкова Е.С.
|
||||
|
||||
# Описание работы приложения
|
||||
|
||||
Приложение реализовано в виде консольного приложения C# с использованием библиотеки BenchmarkDotNet
|
||||
Был создан специальный класс в котором прописаны все методы которые мы хотим замерить
|
||||
ТК по многу раз считать матрицы больших размеров слишком долго взяла для примера матрицы 6 на 6, 12 на 12 и 16 на 16
|
||||
|
||||
# Вывод
|
||||
|
||||
С использованием параллельного алгоритма скорость обработки может увеличиться, особенно при большой размерности матрицы, но нужно быть аккуратными с разделямыми ресурсами
|
||||
В данном примере оптимальная скорость достигается при количестве потоков равном 16.
