f# - MathNet.Numerics not utilizing the Mkl native provider -


i have f# project uses mathnet.numerics linear algebra routines.

i have placed following code in f# module:

module linearalgebra  open mathnet.numerics open mathnet.numerics.linearalgebra.double open mathnet.numerics.linearalgebra.generic  control.linearalgebraprovider <- new algorithms.linearalgebra.mkl.mkllinearalgebraprovider()

but times seeing matrix multiplication remain same whether have line of code enabled or commented out.

i have installed mkl provider nuget package described here: http://christoph.ruegg.name/blog/mathnet-numerics-with-native-linear-algebra.html

and have ensured these 2 dlls copied bin directory: libiomp5md.dll mathnet.numerics.mkl.dll

any ideas how can detect if native provider being used?

the docs bit more date mentioned blog post, seems required steps have been done.

  • how large matrices?
  • are involved matrices dense?
  • is module module linear algebra code in? if not, have made sure module executed - before linear algebra code?

you can verify native provider enabled checking control.linearalgebraprovider right before linear algebra code executed. in v3, calling tostring on provide additional info platform , revision well.
