How to solve the problem?
the error point to the line of code “ERR = cudaMemcpyAsync(m_DEN(STARTA),DEN(STARTA),NPRT)”
And the detailed information by cuda-memcheck are listed

========= ERROR SUMMARY: 1 error

the codes can be run successful in one machine, but it can not work well in the present machine, I don’t know Why. and what should I do?

2

And I found the function “cudaMemcpyAsync” is not first used in this place.
Why the front code can work through,but break here?

3

what mean of the following error? I wish someone can help me
