System Testing with PEST is characterized by remote process invocation and parallelism. (By contrast, Functional Testing is characterized by blocking processes that are sequentially executed)
This says issue the date command on the flintstone host, start the command 'find /' four times in parallel on all linux hosts in the testbed, then issue the date command on the flintstone host again after waiting on all the find commands to complete.
