digitalmars.D.learn - do mir modules run in parallell

Hi

I am wondering if MIR modules run in parallel by default or if I 
can enforce it by a compiler flag?

Thanks

Hey David,

Do you mean unittests run in parallel or mir algorithms 
themselves run in parallel?

Hi Ilya

Thanks for coming back on this and sorry for not being precise. I 
am wondering about the Mir algorithms.

mir-blas, mir-lapack, and lubeck parallelism depend on system 
BLAS/LAPACK library (OpenBLAS, Intel MKL, or Accelerate Framework 
for macos).

mir-optim by default single thread but can use TaskPool from D 
standard library as well as user-defined thread pools.

mir-random was created for multithread programs, check the 
documentation for a particular engine. The general idea is that 
each thread has its own engine.

Other libraries are single thread but can be used in multithread 
programs with Phobos threads or other thread libraries.

Best,
Ilya
