Port all functions from ArrayFire 3.4

[pavanky]

Each header "foo" file should have the following:

• src/foo.cpp
• R/foo.R

Also add tests if possible, though they are not necessary

• test/simple_foo.R
• algorithm
• arith
• array
• blas
• data
• defines (library.py)
• device
• features
• graphics
• image
• index
• lapack
• signal
• statistics
• util
• version (merge with util)
• vision

---

C++ only headers that are not being ported

• exception.h (ported the necessary C function to util.py)
• complex.h
• dim4.hpp
• gfor (are there any necessary bits??)
• constants

Hi there,
I would like to give it try to arrayfire-r, but I have some errors
I would appreciate very much some help with this.
My overall computing skills are pretty basic but I'm willing ;)

This is what I achieved.

Installed Ubuntu 14.04 with AMD Catalyst 15.302 in a Dell7910 with 2 Xeon E5-2609 v3, 32Gb RAM, Fury tri-X R9 GPU
No CUDA, no NVIDIA drives
Tested GPUrat and the benchmarks ran ok
Installed Arrayfire dependencies, compilers etc, but I have some problem with GLFW 3.2 GLX, apparently it compiled from source ok.
Installed Arrayfire 3.3.2
Installed Anaconda and other dependencies
Compiled & ran arrayfire benchmark ok
The CPU benchmarks' run is very slow, only uses one core!

Compiled & run arrayfire examples, but it runtime complained.
For example

./blas_opencl
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast
libGL error: unable to load driver: swrast_dri.so
libGL error: failed to load driver: swrast

1792 x 1792: 4434 Gflops
1920 x 1920: 4087 Gflops
2048 x 2048: 4352 Gflops

peak 4434.43 GFLOPS

Installed Revolutions R with MKL
Installed arrayfire-r without errors
( library("arrayfire", lib.loc="~/R/x86_64-pc-linux-gnu-library/3.2")) seems ok
running the arrayfire-r example it complains and the print result is similar to the piR(num) CPU function:

res = piAF(num)
GLX: Forward compatibility requested but GLX_ARB_create_context_profile is unavailableError: Could not Create GLFW Window!
Error in afRunif(num) : In function random

OpenCL Error (-11): Build Program Failure when calling clBuildProgram
print(res)

@AurelioG I see that the C/C++ version is using 3.3.2 where as you are loading 3.2 for R. Can you try with 3.3 ?

I just ran the same code on an R9 Fury nano and did not get any errors.

If that doesn't work, can you post the output of clinfo over here?

No Joy yet.. I tried 3.0 and could not install properly. I tried different things starting from clean install and probably glfw is a source of headache, arrayfire binaries or compile is another flavour of problems. Here is what works with arrayfire-r

The error you are seeing seems to be coming from the OpenCL driver..

[pavanky]

Apparently this can happen if you have an older version of AMDAPPSDK installed along side the newer version. Can you check if that is the case?

[AurelioG]

Here is the R output with a clean Ubuntu 14.04 install, but my R snippet didn't work. However the errors are different. The arrayfire examples were OK, except for the graphics. This time I didn't install OpenCL GL headers, mesa or other stuff that could interfere with the AMD SDK.

So my question is ¿how to set up a working OpenCL environment for arrayfire-r? I'm not interested (yet) in the arrayfire graphic capabilities. Previously, I tried to disable GLFW when compiling Arrayfire, but I got errors complaining about glfw.

Cheers,
Aurelio

@AurelioG is that the end of the error message ? If not, can you run your script after running export AF_PRINT_ERRORS=1 ?

[AurelioG]

Yes it was the end of the R printout in RStudio! In the the bash terminal worked ok.
How can I make it work in RStudio??

export AF_PRINT_ERRORS=1
R CMD BATCH a.r

@AurelioG let me try out RStudio and see what's going wrong. I have only ever used command line.
