i f the first user has access permission to access each
data set, determining multiple user identifiers corres
ponding to the multiple data sets; acquiring file storage
path information corresponding to each data set; ac
quiring, according to the multiple user identifiers,
identity authentication permission corresponding to
each user identifier; and delivering a parallel access
task to a parallel computing system. B y sending iden
tity authentication permission corresponding to mul
tiple user identifiers and file storage path information
to a computing system, inter-user access can b e
achieved, so that one user can access data sets of mul
tiple users.
