BEMAP

INTRODUCTION

Bemap is a benchmark used to measure parallel hardware performance.

All OpenCL code benchmarks covered in this project are done step-by-step along with hand-tunning. Each tuning step executional time are measured in details with a comprehensive user interface and help option. The exact implementation in native code (C++) is also provided in each project folder for reference.

By analyzing these benchmarks, we may analyze:

• How to tune/optimize using the given Parallel Programming API
• Whether the appropriate optimization procedure is provided within the compiler/hardware

This project is derived from SourceForge site of bemap.

PACKAGES

This package includes:

• Blackscholes for European Call/Put
• GrayScale
• GaussianFilter
• BackProjection
• MonteCarlo for European Call/Put

REQUIREMENTS

• CMake 2.8.x

• OpenCL SDK

  • Intel : http://software.intel.com/en-us/articles/vcsource-tools-opencl-sdk/
  • AMD : http://developer.amd.com/zones/openclzone/Pages/default.aspx
  • NVIDIA : http://developer.nvidia.com/opencl

• After the SDK installation, make sure you have set the SDK path correctly

  • For Intel SDK (Below is just an example using default Intel OpenCL SDK path) export INTELOCLSDKROOT=/opt/intel/opencl/
  • For AMD SDK (Below is just an example using default AMD APP SDK path) export AMDAPPSDKROOT=/opt/AMDAPP/
  • For NVIDIA SDK (Below is just an example using default CUDA Path) export CUDA_PATH=/usr/local/cuda/

ALL WORKLOADS COMPILATION

To build all projects in one compilation, do the following: (You have to ensure that at least cmake 2.8.x is installed)

$ mkdir build
$ cd build
$ cmake ../
$ make

After the above commands, all binaries will then be installed to bin/ folder

Building in Windows

Building in Windows with CMake needs the MS Visual Studio cmake files generator (and also requires Visual Studio to be installed).

$ cmake -G XX

XX is MSVC's version. (xx64 is for 64-bit build) Which may be:

• 6
• 7
• 7 .NET 2003
• 8 2005
• 8 2005 Win64
• 9 2008
• 9 2008 IA64
• 9 2008 Win64
• 10
• 10 IA64
• 10 Win64
• 11 Win64

The above command will create a Visual Studio solution file. It can also be done by using nmake, for example for building in a Cygwin environment.

$ cmake -G NMake\ Makefiles
