报错信息为:
gpu_neighbor_list_setup :: Small box detected, with <= 2 cells in one or more
dimensions. The current GPU code has been deemed
unsafe for these situations. Please alter the
cutoff to increase the number of hash cells, make
use of the CPU code, or (if absolutely necessary)
run pmemd.cuda with the -AllowSmallBox flag. This
behavior will be corrected in a forthcoming patch.
这个报错需要需要理会吗?还是bug直接使用-AllowSmallBox就可以呢?
PS:还有Note: The following floating-point exceptions are signalling: IEEE_UNDERFLOW_FLAG IEEE_DENORMAL,这是正常的吗?
