    Distributed Matrix Memory Pool object to destroy.

public interface CheckMemoryPoolValidity

  • private pure function CheckMemoryPoolValidity_p(this, matrix) result(isvalid)

    Checks if a given distributed memory pool has been validly allocated to handle the given parameters.

    Arguments

    Type IntentOptional AttributesName
    type(MatrixMemoryPool_p), intent(in) :: this

    The memory pool to check.
    type(Matrix_ps), intent(in) :: matrix

    The associated matrix to check against.

    Return Value logical

    True if the memory pool is valid.


Derived Types

type, public :: MatrixMemoryPool_p

A memory pool datatype that can be reused for matrix matrix multiplication. this is to prevent excessive alloc/dealloc.
