Some crunchers report about the computation errors which sometime occur on the current version of application. We are working on fixing this problem right now. It seems that some additional libraries should be added to the application. Right now a cruncher can try fix the problem by installing CUDA toolkit 8.0 on his host. It has alaready helped a couple of times.

Некоторые кранчеры сообщают, что на новой версии приложения появляются ошибки вычислений. Мы работаем над решением этой проблемы. Судя по всему, нужно добавить некоторые дополнительные библиотеки. Прямо сейчас любой кранчер может попытаться решить эту проблему установкой на хост CUDA toolkit 8.0. Это уже помогло несколько раз.

After getting 100% error rate I found this and installed CUDA 8.0 Toolkit.

At least the WUs run, but only 2 of 15 validate. The rest are getting this:

<stderr_txt>
CUDA error at C:/Users/vader/Documents/Visual Studio 2015/Projects/A5_bruteforce/A5_bruteforce/kernel.cu:422 code=30(cudaErrorUnknown) "cudaMemcpyFromSymbol(&h_result, gpu_result, sizeof(gpu_result), 0, cudaMemcpyDeviceToHost)"
</stderr_txt>

The app is still looking for version 7.5.
