Abstract
A parallel filesystem remote access subsystem facilitates remote access to files in a parallel filesystem in a digital computer network, the network including at least one client computer and a plurality of server computers interconnected by a communication link, and each server computer storing a portion of at least one file in the parallel filesystem. The parallel filesystem remote access subsystem includes, associated with the server computer, a parallel filesystem input/output daemon, and, associated with the client computer, a parallel filesystem module and a parallel filesystem proxy daemon. The parallel filesystem module receives access requests generated to access a file in the parallel filesystem and refer the access requests to the parallel filesystem proxy daemon, and the parallel filesystem proxy daemon, in turn, generates server access request messages for transfer over the communications link. The client computer processes the parallel filesystems module in a privileged kernel mode and the parallel filesystem proxy daemon in an unprivileged user mode. The a parallel filesystem input/output daemon, which is processed in the server computer's user mode, controls processing of server access request messages received by the server computer over the communication link.
