back-substitution passes progr.

Здравствуйте!

Коллеги, помогите разобраться, что тут за passes имеется в виду. Это какие-то сигналы? Заранее спасибо!

The forward- and back-substitution passes associated with solving banded linear systems by LU-decomposition
are related to recursive filters, particularly for Toeplitz matrices, although the resulting L and U matrices have nonuniform entries at least near the domain boundaries. Forward- and back-substitution passes can be implemented with parallel scan operations.

Про подстановки я поняла, меня именно passes интересуют.

Здесь это методы.

А здесь что за passes тогда?

While much research has explored parallel recursive filtering, prior techniques do not optimize across the entire filter sequence. Typically, a separate filter (or often a causal-anticausal
filter pair) is required in each dimension. Computing these filter passes independently results in significant traffic to global memory, creating a bottleneck in GPU systems.

Хм. Тогда pass, как вариант, - "полоса", "пропускная способность".
