I read the source code of gromacs-5.0 and find some code like this:<br>
case nbnxnk4x4_PlainC:<br>
...<br>
case nbnxnk4xN_SIMD_4xN:<br>
...<br>
case nbnxnk4xN_SIMD_2xNN:<br>
...<br>
case nbnxnk8x8x8_CUDA:<br>
...<br>
case nbnxnk8x8x8_PlainC:<br>
...<br>
Could you tell me what do these<br>
items(nbnxnk4x4_PlainC,<u></u>nbnxnk4xN_SIMD_4xN,nbnxnk4xN_<u></u>SIMD_2xNN,nbnxnk8x8x8_CUDA,<u></u>nbnxnk8x8x8_PlainC)<br>
