gpucoder can't see nvToolsExt64_1.lib even if it exist ad it's declared correctly in the environement variable NVTOOLSEXT_PATH.

I tried to disable the firewall obtaining the same problem.

What to do ?

I get error:

Error using gpucoder.profile (line 41)
Unable to find NVTX library 'nvToolsExt64_1.lib'. Ensure that the NVTX SDK installation contains the
specified library file.

when I type :

cfg = coder.gpuConfig('exe');
cfg.GpuConfig.MallocMode = 'discrete';
gpucoder.profile('myH_MEX',ARGS{1},'CodegenConfig',cfg,...
    'CodegenArguments','-d profilingdir','Threshold',0.001);

Thanks!

nvtxPath = getenv('NVTOOLSEXT_PATH');
'C:\Program Files\NVIDIA Corporation\NvToolsExt\;C:\Program Files\NVIDIA Corporation\NvToolsExt\lib\x64;'
libListing = dir(fullfile(nvtxPath, 'lib', 'x64'))
0×1 empty struct array with fields:
name
folder
date
bytes
isdir
datenum

SOLVED!

setenv('NVTOOLSEXT_PATH','C:\Program Files\NVIDIA Corporation\NvToolsExt\');

If libListing calls 'lib' & 'x64' you don't need to declare it!

I changed the environement variable too manually!

What is weird is that this was the starting setting but I probably missed something ...

in gpucoderSetup all is OK & in coder.checkGpuInstall it returns :

gpu: 1
cuda: 1
cudnn: 1
tensorrt: 0
basiccodegen: 1
basiccodeexec: 1
deepcodegen: 0
deepcodeexec: 0
tensorrtdatatype: 0
profiling: 0

Why does it give me profiling: 0 ?

When I run :

cfg = coder.gpuConfig('exe');
cfg.GpuConfig.MallocMode = 'discrete';
gpucoder.profile('tvd_sim2_MEX',ARGS{1},'CodegenConfig',cfg,...
    'CodegenArguments','-d profilingdir','Threshold',0.001);

it works but now I have a new problem:

nvprof.exe stopped working
UnknownServerPort_Diagnostics - 0
UnknownServerPort_Diagnostics - 1
UnknownServerPort_Diagnostics - 2
Error using gpucoder.profile (line 41)

coder.checkGpuInstall by default does not do any profiling checks. To perform these checks, you need to set the Profiling property of the coder.gpuEnvConfig object to true before passing the config to coder.checkGpuInstall.
