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.

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
