Hello, I'm sorry that this is off-topic, but I think many people here would be able to answer this question easily. The unix system in my research center has a file server with 4 CPUs. I don't know all the specifics of the machine, but my question is rather general anyway. Basically, the file server is the fastest of all the Sun stations by far, so everyone logs into it to run their jobs. Some of these jobs last for several days and are very processor intensive. It "feels" to me like my I/O intensive jobs slow down when these processor-intensive jobs are running. However, our sysadmin insists that cpu-intensive jobs will have no effect on I/O intensive jobs. Is this generally true?
Thanks very much for any information you can give me. I would like to make the case that the file server should be just a file server and that all these week-long jobs should be run somewhere else, but I just don't know if that is a valid argument.
