super computer 不是这样用的。中文输入好累，请允许我打英文。
Nodes of a supercomputer, such as Tianhe II, are divided into two types: interactive nodes and computing nodes.
Interactive nodes are for the interaction with users.We use those nodes for editing files, compiling programs and submitting jobs. We may run the program on those nodes by './program'. But the computing is conducted on interactive nodes of which the performance are usually bad.
To drain the performance of a supercomputer, we should submit our program to one or more computing nodes. We usually write a job description file specifying the program we want to run, resources we need during computing and the expected running time/duration of our program. We submit our job to computing nodes via the job management system that reads info from the job description file. In this way, the computing is conducted on the powerful, resourceful and high speed computing nodes.
Different supercomputers have different job management systems. I have ever used systems of IBM and Cray.
