Re: [gmx-users] Gromacs installation with GPU support in Windows 7

My bad, I missed a line in the warning message:

Building NVCC (Device) object 
src/gromac/CMakeFiles/libgromacs.dir/mdlib/nbnxn_cuda/Release/libgromacs_generated_nbnxn_cuda.cu.obj

   CMake Warning (dev) at

   Argument not separated from preceding token by whitespace.
 This warning is for project developers. Use -Wno-dev to suppress it.

Hi,


I've implemented the fix and I verified that it works on the command line; I've 
successfully complied the nvcc depend file.

Nonetheless, CMake still fails on compiling in that stage. Here is the error 
message in Visual studio 2015

CMake Error at libgromacs_generated_nbnxn_cuda.cu.obj.Release.cmake:223

If this is of any use, there's also an accompanying warning message appearing 
right before the error message I showed above:

   Argument not separated from preceding token by whitespace.
 This warning is for project developers. Use -Wno-dev to suppress it.

The system specs I'm using:

  *   Windows 7
  *   VS 2015
 *   VS 2015 developer prompt to manually compile the file CMake was trying 
to compile
  *   CMake 3.11 GUI
  *   CUDA v9.1 - I've verified my CUDA installation with the provided build 
examples.
  *   Graphics card: GTX 1080


I do not know if CMake deals with whitespace paths, but when compiling 
manually, I had to make sure to add quotes around my cuda path and my --ccbin 
path because they are installed in directories with whitespaces.

Any help would be greatly appreciated.

Harry

Hello Harry,

Thank you for the report. It seems to be a trivial error in the code,
indeed.
It was not caught by the Gromacs automated testing since we don't have
Windows + CUDA configuration in it.
I have filed a bug report https://redmine.gromacs.org/issues/2509 and this

will be fixed in Gromacs 2018.2.
Meanwhile you can easily fix it yourself.
The line 646 of your src/gromacs/mdlib/nbnxn_cuda/nbnxn_cuda.cu looks like
stat = cudaStreamQuery(stream);
and you only have to remove the unused (and undeclared) "stat = " variable,
turning the line into:
cudaStreamQuery(stream);
Please don't hesitate to report if there are any more errors :-)

[gmx-users] Gromacs installation with GPU support in Windows 7

2018-05-21 Thread Jia Hong 
Aim: Install Gromacs with GPU support in windows 7


Problem: Build step failed in Visual Studio 14 2015, using CMake 3.11 GUI in 
Windows


Identified "issues":

  1.  First off, NVIDIA named their default CUDA installation directory in a 
space separated directory. This caused much grief when CMake complains that 
"Check for working NVCC/C compiler combination - broken" and "CUDA compiler 
does not seem to be functional".
 *   The solution was to surround the path with quotes in 
CUDA_TOOLKIT_ROOT_DIR
  2.  Visual Studio fails to compile libgromacs (VS complains that it could not 
find ../../lib/gromacs.lib


With regards to (2.), CMake completed the generation of VS build files without 
errors and I tried building it using VS 14 2015 (as specified in my CMake 
generation tool). The steps I took:

  1.  set the build type to Release
  2.  click build all


I also tried compiling Gromacs with the exact same steps, but without GPU 
support, and it went without a hitch.


I therefore suspect that it might be that "path issue" I faced earlier (1.), so 
I tried identifying the first error in VS build and it lead me to 
src/gromacs/mdlib/nbnxn_cuda/nbnxn_cuda.cu.


I copied the commands as-is within the makefile and tried to compile it in VS 
developer command prompt myself.


The error I got was:

C:/tools/GROMACS/gromacs-2018.1/src/gromacs/mdlib/nbnxn_cuda/nvnxn_cuda.cu(646):
 error: expression must be a modifiable lvalue.



My suspicion is that:

  1.  The error "might" be because of a path problem ? (like before)
  2.  nvnxn_cuda.cu at line 646 has a syntax error. (maybe)


Any help would be greatly appreciated.


Regards,

Harry.
