# mkl-service

This package exposes a few functions which are declared in mkl_service.h. The main purpose of the package is to allow the user to change the number of CPU’s MKL is using at runtime.

## Example:

In this small example, we first query how many CPU are being used, and then change this number.

    >>> import mkl
    >>> mkl.get_max_threads()
    2
    >>> mkl.set_num_threads(1)
    >>> mkl.get_max_threads()
    1

## Reference

mkl service functions:

`mkl.get_cpu_clocks()` -> int
  Return the CPU clocks as an integer.
`mkl.get_cpu_frequency()` -> float
  Return CPU frequency in GHz as a float.
`mkl.get_max_threads()` -> int
  Return the number of threads Intel MKL is targeting for parallelism.
`mkl.get_version_string()` -> str
  Return the MKL library version information as a string.
`mkl.mem_stat(n)` -> int
  Returns an amount of memory, allocated by the MKL Memory Allocator.
`mkl.set_num_threads(n)`
  Set the number of threads MKL should use. This is only a hint, and no guaranteed is made this number of threads will actually be used. This function takes precedence over the environment variable MKL_NUM_THREADS.
