In the notes it discussed 64bit calculations, does the GPU need to be double precision?

No, the app stores the histogram of interatomic distances in a 64-bit integer (or long long integer) array, it does not use double precision.

Hi, i try run for several days on "best" DP gpu ati 7970 and also older nvidia cards for other reason . but it was waste time.you can catch to see App-times in my setup and computer- valid app

This project is Great programed for last nvidia pascal arch.
(unfortunately i have only one pascal

Hi,
I'm not sure that I understood correctly, but note that the apps do not use double-precision floating point operation on GPU (only 64-bit integers), so GPUs with high performance in double precision do not have advantages in this project.
