I'm on Ubuntu 17.04 (64-bit) with a 6 GB GTX 1060 with 1280 CUDA Cores.

Any advice?

[blueberry]

do you have intel mkl on your path? the message complains that neanderthal can't fond libmkl_rt.so

[aaelony]

that's right. Looking for docs on how to install libmkl_rt.so

[MrEbbinghaus]

@aaelony You can get it here: https://software.intel.com/en-us/intel-mkl

[aaelony]

thanks

[aaelony]

actually perhaps ubuntu 17.04 is not yet supported by Intel?

Most linux distributions are "unsupported", but it installs on them just fine. Moreover, you do not even need to i stall it properly - since you do not need to compile any binaries with mkl (I already did that) it is enough to obtain te libXXX.so anyhow add put them on your machine. It is all explained in the Gettimg atarted guide on the neanderthal website.

additionally, ubunty may have some shenanigans on its own when it comes to setting LD_LIBRARY_PATH for java, but that is solvable (see the previous issus related to ubumtu and atlas - Goran Jovic wrote a blogpost and put a link to it in that github issue thread).

iphone keyboard :) it seems there is no editing option in mobile...

[MrEbbinghaus]

@blueberry I had to install the MKL libraries. I don't know exactly why, but my REPL wouldn't work correctly.

[blueberry]

@mroerni just to be clear: when you installed mkl, everything works fine?

btw i tested that: removed mkl installation, everything works fine with library files at the right place...

[MrEbbinghaus]

@blueberry I removed the mkl libs and started a repl. Following error:

formons.core=> (require 'uncomplicate.neanderthal.native)

  Reason: image not found, compiling:(uncomplicate/neanderthal/internal/host/mkl.clj:98:5) 

I reinstalled the libs and restarted the repl. (require 'uncomplicate.neanderthal.native) => works.

[blueberry]

hey, wait! when you remove mkl, you have to place (copy) mkl's libxxx.so files in a folder, and add that folder to LD_LIBRARY_PATH, of course. This is nothing mkl specific, that's how linux dynamic libraries work..

[blueberry]

now i see that you're on osx. in that case, you should add that folder to DYLD_LIBRARY_PATH. see the getting started guide.

[MrEbbinghaus]

Ah nevermind. I was confused because you said, that you removed mkl.

[blueberry]

I removed the installation and tested the manual way. I have to keep the installatiom though because it is required for neanderthal-mkl compilation. you,the user, have more options.

[blueberry]

@aaelony What happened? Did you succeed setting it up?
