NVIDIA CUDA Toolkit v5.5 for POWER8

NVIDIA CUDA Toolkit v4.0 Release Notes of the newest one. CUDA project files previously specified the include paths to be

$(CUDA_PATH)\include

. To address this, SDK sample projects now specify either

$(CudaToolkitIncludeDir)

or

$(CudaToolkitDir)\include

.

3. Individual SDK solutions from VS2005, VS2008, VS2010 do not build properly.

Each SDK sample solution may depend on

cutil

,

shrUtils

, or

oclUtils

libraries which are also part of the SDK. In order to build with the proper dependencies, developers needed to open the

release_vs200?.sln

solution file for all dependencies to work. The individual SDK sample solutions for CUDA, CUDALibraries, and OpenCL now include dependencies from individual solution files.

‣

In some cases, Visual Profiler global memory derived statistics and hints may be incorrect. If the kernel has local memory accesses, the derived statistics-

global memory excess load %

and

global memory excess store %

can yield incorrect results. This is because the L2 throughput that is used to calculate these values include local memory accesses too. As a result, the hints which use these statistics are incorrect as well since the excess loads given by this formula are caused due to the local memory accesses (in addition to possibly uncoalesced memory access pattern)

‣

In a multi-gpu setup, when compute mode is set to

compute prohibited

for some GPUs, the Visual Profiler cannot profile a CUDA runtime application; Visual

Profiler reports an error and profiling data is not shown.

‣ CudaHostRegister()

is not supported in RHEL4. Please refer to the NVIDIA

CUDA C Programming Guide for details on

CudaHostRegister()
