Using broadcast fails with OptFramework error #122

Open zerocewl opened 7 years ago

zerocewl commented 7 years ago

Hello, I tried to use @acc function br(N) b=collect(1:N); broadcast(+,b,b')end

but this error comes up

julia> br(1000)

Any suggestions for this error? Maybe any openblas path or variable is missing?

I'm using Win 7 with Julia 0.4.6:

Platform Info:
  System: Windows (x86_64-w64-mingw32)
  CPU: Intel(R) Core(TM) i5-3570 CPU @ 3.40GHz
  WORD_SIZE: 64

My config.jl in ParallelAccelerator\deps\generated looks like that:

backend_compiler = USE_MINGW
openblas_lib = "libopenblas64_"
mkl_lib = ""
sys_blas = 0

My Windows config.jl looks similar to yours but I'm unable to replicate this issue for some other reasons. However, I can at least confirm that even though libopenblas.dll is present that cblas.h is not. I'm not an openblas expert but I do believe it uses cblas.h so maybe this is some Windows Julia thing about it being missing.

I did try your example with Julia 0.5 with PROSPECT_MODE=threads and it works. With 0.5 and PROSPECT C mode, there is an issue where we can't compile the collect function that is explicitly called here.
