Abstract
In order to meet the demands of the users with different backgrounds to get the best performance of CFIO(Climate Fast I/O)Library, the paper designs and implements a solution of automatic parameter selection, which is based on CFIO. The solution based on the I/O Trace collected by the pre-excution contains the bandwidth testing routine, the trace analysis routine and the parameter selection routine. The user will get the best CFIO parameters after running these routines in command line terminal. The results of the experiments show that under the parameters these routines provided, the I/O phase can be perfectly overlapped by the computing phase with the least computing resource.关键词
