Phoronix OpenCL Benchmark 3.0 beta

So you want OpenCL-benchmarks? Phoronix is a benchmark for OSX and Linux, created by Michael Larabel, Matthew Tippett (http://en.wikipedia.org/wiki/Phoronix_Test_Suite). On Ubuntu Phoronix version 2.8 is in the Ubuntu “app store” (Synaptic), but 3.0 has those nice OpenCL-tests. The tests are based on David Bucciarelli‘s OpenCL demos. Starting to use Phonornix 3.0 (beta 1) is done in 4 easy steps:

  1. Download the latest beta-version from http://www.phoronix-test-suite.com/?k=downloads
  2. Extract. Can be anywehre. I chose /opt/phoronix-test-suite
  3. Install. Just type ./phoronix-test-suite in a terminal
  4. Use.

WARNING: It is beta-software and the following might not work on your machine! If you have problems with this tutorial and want or found a fix, post a reply.

Let’s start with listing all tests:

> ./phoronix-test-suite list-available-suites

Generating this takes a while, so here are the results for the impatient:

OpenCL

You saw the bold-printed “OpenCL”. We can start the test with:

> ./phoronix-test-suite benchmark pts/opencl

In my case I got a message

The following dependencies are needed and will be installed:

- libsdl1.2-dev
- libsdl-gfx1.2-dev
- libsdl-net1.2-dev
- libsdl-image1.2-dev
- libsdl-ttf2.0-dev
- lib3ds-dev

It was automatically installed, so very user-friendly. So it *seems* to work well, but then the error-messages pop up.

Fixing the tests

The tests are made for 64-bit Linux with an AMD/ATI GPU. You might not have it.

Go to ~/.phoronix-test-suite/installed-tests/pts/juliagpu-1.1.0 and open the zip-file. In the zip-file you need to edit “Makefile”, which looks like this:

(...)
ATISTREAMSDKROOT=/home/david/src/ati-stream-sdk-v2.0-lnx64

CC=gcc
CCFLAGS=-O3 -msse2 -mfpmath=sse -ftree-vectorize -funroll-loops -Wall 
-I$(ATISTREAMSDKROOT)/include -L$(ATISTREAMSDKROOT)/lib/x86_64 -lglut -lglut -lOpenCL

# Jens's patch for MacOS, comment the 2 lines above and un-comment the lines below
#CCFLAGS=-O3 -ftree-vectorize -msse -msse2 -msse3 -mssse3 -fvariable-expansion-in-unroller 
#    -cl-fast-relaxed-math -cl-mad-enable -Wall -framework OpenCL -framework OpenGl -framework Glut
(...)

So there is a patch to get it working on Apple (you lucky folks!). For BSD/Linux we need to patch this, to get it also working with NVIDIA-32, NVIDIA-64 and AMD-32 from the right directory. Just edit the Makefile from the zip as below (uncomment the right driver and fix the location).

# NVIDIA 32
#OPENCLLIB=/usr/local/cuda/lib/
#OPENCLINC=/usr/local/cuda/include/

# NVIDIA 64
#OPENCLLIB=/usr/local/cuda/lib64/
#OPENCLINC=/usr/local/cuda/include/

# AMD 32
#OPENCLLIB=/opt/ati-stream-sdk-v2.0-lnx32/lib/x86
#OPENCLINC=/opt/ati-stream-sdk-v2.0-lnx32/include

# AMD 64
#OPENCLLIB=/opt/ati-stream-sdk-v2.0-lnx64/lib/x86_64
#OPENCLINC=/opt/ati-stream-sdk-v2.0-lnx64/include

CC=gcc
CCFLAGS=-O3 -msse2 -mfpmath=sse -ftree-vectorize -funroll-loops -Wall 
-I$(OPENCLINC) -L$(OPENCLLIB) -lglut -lglut -lOpenCL

# Jens's patch for MacOS, comment the 2 lines above and un-comment the lines below
#CCFLAGS=-O3 -ftree-vectorize -msse -msse2 -msse3 -mssse3 -fvariable-expansion-in-unroller 
#    -cl-fast-relaxed-math -cl-mad-enable -Wall -framework OpenCL -framework OpenGl -framework Glut
(...)

Save the file and say yes to update the zip-file. We can test the fix with:
> ./phoronix-test-suite benchmark pts/juliagpu-1.1.0

If it works, you can make the same changes for pts/mandelbulbgpu-1.1.0, pts/smallpt-gpu-1.1.0 and pts/mandelgpu-1.1.0

Bad luck? Try your luck with the originals of these tests.
