2 Intel Compiler and Libraries for the Android NDK

3 Parallel Studio Installation For optimal performance on Intel Android devices, use the Intel compiler and libraries. You can download C++ Composer, or even the full Parallel Studio. A free 1 year (renewable) linux license for non commercial users are available from : Trial 30 days versions are also available for all other users from :

4 Parallel Studio Installation Ubuntu : sudo apt-get install gcc-multilib Unpack and launch : sudo./install.sh Edit your.bashrc file and add : source /opt/intel/bin/compilervars.sh ia32 (select ia32 even on a 64bit build machine) Restart a shell, and test : icc -v

5 GCC Build optimization Change the build from debug to release with 03 flags in Application.mk : APP_OPTIM := release APP_CFLAGS := -O3

6 Intel Compiler in the Android NDK cd NDK_dir mkdir -p toolchains/icc13/prebuilt ln -s /opt/intel/composerxe/ toolchains/icc13/prebuilt/intel cp toolchains/x86-4.6/*.mk toolchains/icc13/

7 Intel Compiler in the Android NDK Edit setup.mk (delete existing references) : TOOLCHAIN_NAME := icc13 TOOLCHAIN_PREFIX := $(TOOLCHAIN_ROOT)/prebuilt/intel/bin/ export ANDROID_GNU_X86_TOOLCHAIN=$ (TOOLCHAIN_ROOT)/../x86-4.6/prebuilt/linux-x86/ export ANDROID_SYSROOT=$(call host-path,$(sysroot)) TARGET_CC:=$(TOOLCHAIN_PREFIX)icc TARGET_CXX:=$(TOOLCHAIN_PREFIX)icpc TARGET_LD:=$(TOOLCHAIN_PREFIX)xild TARGET_AR:=$(TOOLCHAIN_PREFIX)xiar TARGET_STRIP:=$(ANDROID_GNU_X86_TOOLCHAIN)i686-linuxandroid/bin/strip TARGET_LIBGCC:=$(shell env ANDROID_GNU_X86_TOOLCHAIN=$ (ANDROID_GNU_X86_TOOLCHAIN) $(TARGET_CC) -print-libgcc-filename) # -m32 is needed if you are on a 64bit machine : TARGET_LDFLAGS := -m32 TARGET_x86_release_CFLAGS := -O2 -m32 -g

8 Intel Compiler in the Android NDK Go to your project jni folder and rebuild with the new toolchain : ndk-build -B V=1 NDK_TOOLCHAIN=icc13 Try run as android application : it won't work. Check the intel dependencies : ldd../libs/x86/libhello-jni.so grep intel libsvml.so => /opt/intel/.../lib/ia32/libsvml.so libirng.so => /opt/intel/.../lib/ia32/libirng.so libintlc.so.5 => /opt/intel/.../lib/ia32/libintlc.so.5

9 Intel Compiler in the Android NDK Go to your project jni folder and rebuild with the new toolchain : ndk-build -B V=1 NDK_TOOLCHAIN=icc13 Try to run the app : it won't work. Check the intel dependencies : ldd../libs/x86/libhello-jni.so grep intel libsvml.so => /opt/intel/.../lib/ia32/libsvml.so libirng.so => /opt/intel/.../lib/ia32/libirng.so libintlc.so.5 => /opt/intel/.../lib/ia32/libintlc.so.5

10 Intel Compiler in the Android NDK To ask the NDK to package the 3 linked intel libraries with your app, edit Android.mk : include $(CLEAR_VARS) LOCAL_MODULE := libintlc LOCAL_SRC_FILES := libintlc.so include $(PREBUILT_SHARED_LIBRARY) include $(CLEAR_VARS) LOCAL_MODULE := libirng LOCAL_SRC_FILES := libirng.so include $(PREBUILT_SHARED_LIBRARY) include $(CLEAR_VARS) LOCAL_MODULE := libsvml LOCAL_SRC_FILES := libsvml.so include $(PREBUILT_SHARED_LIBRARY)

11 Intel GPA - Graphics Performance Analyzer

12 Graphics Performance Analyzer Intel GPA is very interesting to monitor and debug graphics. It works with both Windows and Android apps, and the tool can run on Windows, OSX, Android. Download and unzip from : Ubuntu : sudo apt-get install sharutils Install : sh intel-gpa_12.5_x64.deb.shar (if you are on a 64b machine) sudo dpkg -i intel-gpa_12.5_m64.deb

13 Graphics Performance Analyzer Run : gpa-system-analyzer ADB path : GPA may ask you for the ADB path. Example : /home/intel/adk/sdk/platform_tools/adb

14 Graphics Performance Analyzer If you click on the device of your choice (in my case an USB attached smartphone), you should see the list of apps :

15 Graphics Performance Analyzer Select an app, the app will be launched, debugger attached and live graph displayed. You can drag and drop metrics on the graphs :
