The API interfaces provided by CUDA can help programmers develop CUDA applications and get high performance in GPU. However, many of the I/O operations are not supported in device codes. This paper has implemented most of the I/O functions through host's agent by using the characteristics of mapped memory in CUDA, such as read/write file and ¡®printf'. The methods that used to implement these I/O...
We investigate the noise-induced transport of Brownian particle in a deterministic spatial symmetrical periodic potential driven by colored cross correlation between a multiplicative white noise and an additive white noise. We derive the general formula of the stationary current. Based on numerical computation, we found that directed motion of the Brownian particles can be induced by the correlation...
