3 GPU Hardware Nvidia GPUs codesigns30: GeForce 8800 GTS 512 codesigns42: GeForce GTX 285 codesigns43: GeForce GTX 285 codesigns46: Tesla C2050 (SSH only) codesigns46: Tesla K20 (SSH only) AMD GPUs codesignsxx: Radeon HD 5870 codesignsxx: Radeon HD 6970 ARM GPUs codesignsxx: 2x ARM Mali T604 (Arndaleboard/Nexus 10) May 15, 2014 Oliver Reiche Hardware/Software Co-Design Project Discussion 2

4 Hardware Tilera codesigns35: Tilera TILEPro64 AMD CPU codesigns48: AMD Opteron Quad-Core (48 cores) OpenMPI Cluster all machines in room : 20 Intel Core i7, 4 cores (8 SMT cores), 8GiB RAM Gbit network May 15, 2014 Oliver Reiche Hardware/Software Co-Design Project Discussion 3

5 Software Nvidia CUDA 6.0 OpenCL 1.1 AMD APP SDK 2.9 OpenCL 1.2 Android Renderscript SDK 17 (Android 4.2.2) NDK 9d Tilera MDE 3.0 MPI Threading Building Blocks 3.0 OpenMPI 1.6 gcc May 15, 2014 Oliver Reiche Hardware/Software Co-Design Project Discussion 4

6 Environment CUDA set environment for CUDA module load cuda CUDA SDK (/opt/cuda/sdk) examples (sources) in /opt/cuda/sdk/c/src binaries in /opt/cuda/sdk/c/bin/linux/release link against CUDA SDK add the following to your Makefile: # set directory for common. mk CUDA_SDK_PATH?= / opt / cuda / sdk ROOTDIR := $( CUDA_SDK_PATH )/ C/ src ROOTBINDIR := bin ROOTOBJDIR := obj include $( CUDA_SDK_PATH )/ C/ common / common. mk tidy clobber clean -rf bin obj May 15, 2014 Oliver Reiche Hardware/Software Co-Design Project Discussion 5

7 Environment OpenCL set environment for OpenCL on Nvidia GPUs module load cuda CUDA SDK (/opt/cuda/sdk) examples (sources) in /opt/cuda/sdk/opencl/src binaries in /opt/cuda/sdk/opencl/bin/linux/release link against CUDA SDK add the following to your Makefile: # set directory for common. mk CUDA_SDK_PATH?= / opt / cuda / sdk ROOTDIR := $( CUDA_SDK_PATH ) ROOTBINDIR := bin ROOTOBJDIR := obj include $( CUDA_SDK_PATH )/ OpenCL / common / common_opencl. mk tidy clobber clean -rf bin obj May 15, 2014 Oliver Reiche Hardware/Software Co-Design Project Discussion 6

8 Environment Tilera set environment for Tilera module load tilera Tilera MDE / opt / tilera May 15, 2014 Oliver Reiche Hardware/Software Co-Design Project Discussion 7

9 Environment Renderscript Either use SDK or NDK: SDK simply Eclipse NDK link against native Renderscript (C++) add the following to your CMakeLists.txt find_package ( RenderScript REQUIRED ) file ( GLOB PROJECT_CPP *. cpp ) file ( GLOB PROJECT_RS *. rs *. fs) rs_wrap_scripts ( PROJECT_CPP ${ PROJECT_RS }) rs_definitions () rs_include_directories () rs_link_libraries (${ PROJECT_NAME } stdc ++) rs_add_executable (${ PROJECT_NAME } ${ PROJECT_CPP }) May 15, 2014 Oliver Reiche Hardware/Software Co-Design Project Discussion 8

10 Environment OpenMPI set environment for OpenMPI: export PATH =/ usr / lib64 / mpi / gcc / openmpi / bin :${ PATH } export LD_LIBRARY_PATH =/ lib64 :/ usr / lib64 :${ LD_LIBRARY_PATH } advice: put this into your shell s config file (e.g..bashrc) execute programs mpirun -np machinefile mymachines myprogram A machine file will be provided.

11 Login Each group gets one account: SSH + (Mercurial Git Subversion) SSH one user account per group: mappraktx external login via gateway codesigns14: ssh mappraktx@codesigns14. informatik. uni - erlangen. de from there all codesignsxx servers are reachable Repositories Mail us your public SSH key and choose a repository type: Mercurial hg clone ssh://mapsvn@codesigns14.informatik.uni-erlangen.de/seminar/map14/mappraktx Git git clone ssh://mapsvn@codesigns14.informatik.uni-erlangen.de/seminar/map14/mappraktx.git Subversion svn co svn+ssh://mapsvn@codesigns14.informatik.uni-erlangen.de/seminar/map14/mappraktx May 15, 2014 Oliver Reiche Hardware/Software Co-Design Project Discussion 10

12 Tentative Schedule status meetings every two weeks project presentations CW 28: CW 29: project: up to 2 students form a group project presentation: duration: (20+5) min group presentation language: English or German, as you like May 15, 2014 Oliver Reiche Hardware/Software Co-Design Project Discussion 11
