Though Rather slightly off topic, can I use openblas instead of MKL? If it’s a matter of changing the name of library in loadLibrary… Or else?

@chunsj No. OpenBlas is BLAS only, while MKL also implements LAPACK and lots of other extra functions that Neanderthal uses.

@blueberry: does either OpenCL, Neandertheral, or Cuda have an webasembly backend ?

I'm trying to write one piece of code, and have it be able to run both on my dual 1080 GTX as well as webassembly

I don't know.

okay, but I guess there's no plan to have WebAsembly as a backend to Neanderthal, so I'm on my own if I want this ?

never say never

@blueberry I'm on Linux and have MKL for it. I moved all the mentioned libs (literally copied them) to /usr/local/lib. Actually, let me just give the list here of the ones I moved:

`libiomp5.so libmkl_avx2.so libmkl_avx512.so libmkl_core.so libmkl_def.so libmkl_intel_lp64.so libmkl_intel_thread.so libmkl_rt.so libmkl_vml_def.so`

Most things work, but when playing around with the new flare lib (for rnns) I stumbled at one point upon this:

java: symbol lookup error: /tmp/libneanderthal-mkl-0.17.0283772954573527292.so: undefined symbol: vdFmax

Presumably I need to move another lib (or more) to where it is visible, but I'm not sure which or what. Thanks for any info!

@blueberry hello! I want to try to execute simple OpenCL function

@jsa-aerial are you sure you have the latest MKL 2018?

@rustam.gilaztdinov Your mac supports OpenCL 1.2, so you have to use a few legacy functions with -1 suffix in names. See the docs and the hello-world example, particularly https://github.com/uncomplicate/neanderthal/blob/master/examples/hello-world/src/hello_world/opencl1.clj

@blueberry No - I just figured that out (before seeing your msg) and now have 2018 installed. I will test and confirm it works. Thanks.

@blueberry That was it alright. Confirmed: with new 2018 install all tests pass. Thanks again!
