Attempt to reconstruct an [`Algorithm<T>`] from a stored solver name string. Returns `None` when the name is unrecognised or the algorithm requires s

All-gather operation: gather data from all processes. # Errors Returns `MpiError::SizeMismatch` if receive buffer is too small.

All-to-all communication for complex data. Each process sends `count` elements to each other process. Total send/receive size is `count * num_process

Allocate an aligned buffer for complex values. The returned vector is guaranteed to have its data pointer aligned to `DEFAULT_ALIGNMENT` bytes (64 by

Allocate an aligned buffer for complex values with guaranteed alignment. The returned buffer is guaranteed to have its data pointer aligned to `DEFAU

Allocate an aligned buffer for real values. Note: This returns a standard Vec which may not be aligned. For guaranteed alignment, use `AlignedBuffer:

Allocate an aligned buffer for real values with guaranteed alignment. The returned buffer is guaranteed to have its data pointer aligned to `DEFAULT_

Calculate total local allocation size for a multi-dimensional array. For a distributed array where the first dimension is distributed, returns local_

Check if two complex vectors are approximately equal.

Check if two complex vectors are approximately equal.

Returns true if fast ≈ direct within relative tolerance `rel_tol` or absolute tolerance `abs_tol`.

Check that two values agree within combined absolute and relative tolerance. This avoids false failures when both values are near zero (floating-poin

Compile-time assertions that all public plan types implement `Send + Sync`. This module contains a single never-called function whose body consists o

Helper: assert that a type is both Send and Sync.

Tolerance check for pure-AVX (no FMA): relative 1e-12 floor.
