Android (outdated instructions)
|
||||||
|
------------------
|
||||||
|
|
||||||
|
Assuming you have a recent Android NDK available, you can use the
|
||||||
|
toolchain that it provides to build GPU-STREAM. You should first
|
||||||
|
use the NDK to generate a standalone toolchain:
|
||||||
|
|
||||||
|
# Select a directory to install the toolchain to
|
||||||
|
ANDROID_NATIVE_TOOLCHAIN=/path/to/toolchain
|
||||||
|
|
||||||
|
${NDK}/build/tools/make-standalone-toolchain.sh \
|
||||||
|
--platform=android-14 \
|
||||||
|
--toolchain=arm-linux-androideabi-4.8 \
|
||||||
|
--install-dir=${ANDROID_NATIVE_TOOLCHAIN}
|
||||||
|
|
||||||
|
Make sure that the OpenCL headers and library (libOpenCL.so) are
|
||||||
|
available in `${ANDROID_NATIVE_TOOLCHAIN}/sysroot/usr/`.
|
||||||
|
|
||||||
|
You should then be able to build GPU-STREAM:
|
||||||
|
|
||||||
|
make CXX=${ANDROID_NATIVE_TOOLCHAIN}/bin/arm-linux-androideabi-g++
|
||||||
|
|
||||||
|
Copy the executable and OpenCL kernels to the device:
|
||||||
|
|
||||||
|
adb push gpu-stream-ocl /data/local/tmp
|
||||||
|
adb push ocl-stream-kernels.cl /data/local/tmp
|
||||||
|
|
||||||
|
Run GPU-STREAM from an adb shell:
|
||||||
|
|
||||||
|
adb shell
|
||||||
|
cd /data/local/tmp
|
||||||
|
|
||||||
|
# Use float if device doesn't support double, and reduce array size
|
||||||
|
./gpu-stream-ocl --float -n 6 -s 10000000

Drivers, compiler and software applicable to whichever implementation you would like to build against. Our build system is designed to only build implementations in programming models that your system supports.
|
|
||||||
|
|
||||||
Generate the Makefile with `cmake .`
|
We have supplied a series of Makefiles, one for each programming model, to assist with building.
|
||||||
|
The Makefiles contain common build options, and should be simple to customise for your needs too.
|
||||||
|
|

Android (outdated instructions)
|
General usage is `make -f <Model>.make`
|
||||||
------------------
|
Common compiler flags and names can be set by passing a `COMPILER` option to Make, e.g. `make COMPILER=GNU`.
|
||||||
|
Some models allow specifying a CPU or GPU style target, and this can be set by passing a `TARGET` option to Make, e.g. `make TARGET=GPU`.
|

Assuming you have a recent Android NDK available, you can use the
