Error when running compiled GPU-Debug x64 version of dualsphysics

falke

The compilation of the GPU Debug x64 version works fine and without errors.

Although i did no changes in the source code, i always get the following error,
when running for different cases:

[Initialising simulation (z9670qc0) 26-06-2015 09:46:53]
PART PartTime TotalSteps Steps Time/Seg Finish time
========= ============ ============ ======= =========
Exception (JSphGpuSingle::Interaction_Forces)
Text: Failed in reduction of viscdt. (CUDA error: invalid resource handle).

The error happens after initializing the run and at the beginning of step 1,
in JSphGpuSingle::Interaction_Forces

I have absolutely no plan how to solve it.

Compiler: Visual Studio 10 and Cuda5.5

Compilation and Running the GPU Release x64 version works fine.

You have to update your GPU driver first

Thank you Alex for the hint!
Unfortunately the update to the newest driver version and recomiling did not eliminate the error.
It´s a little bit strange since running the compiled release version works fine.

Also compiling with Cuda6.0 shows the same error...
Are there some specific essential steps when compiling/running the debugX64 version?

Am I the only one who gets this error?

gfourtakas

you are running the "GPU Debug x64" version, the project has been set up only for the release if I remember correctly.

please try the release, do you get errors there?

You might have to set up you debug version on your machine on your own..

let me know and I might give you some tips if you have issues.

Thanks,
George
