Simul Parallel File System Test Tool

Simul is a benchmark stress test that simulates a number of clients making system calls to the Lustre file system simultaneously. Syscalls may be made from one or more threads on one or more nodes.

Operations include open, close, file stat, lseek, read, write, chdir, dir stat, readdir, mkdir, rmdir, unlink, rename, creat, truncate, symlink, readlink, and link. Is this list correct?
