Hello everyone, I am currently running the GPU version of croco. Now I have a problem: with the CPU version, it can run normally for over 360 days before blowing up, but when using the GPU version, it blows up in less than a day. Why is this? Besides using GPU computation, I haven’t made any other changes. Thank you all for your answers.
Any help is appreciated, thanks!

Hello Zhixin,
It looks a variable (at initial time ou near) is not copy to the GPU. One of the forcing variable is the first probability ?
I sow yours cppkeys keys, i can try to reproduce the problem on a test case.
Iin addition, and apart from this problem, with OpenACC and compiller optimisation CPU and GPU will not have same results.
There is a CVTK keys to run and fix the reproductility in developpement mode.
Let me know !
