Get the program and compile it

1.

From the class web page, get the ``Cache-testing program'', unpack it and compile it.

2.

Read the code. It's actually C, not C++, but for codes like this it almost doesn't matter. There are some system calls and things here that we will probably want to use later, so keep this program around for future reference.

3.

Run the program on one of the SGI workstations, redirecting the output into a file. For example, cache > data will put the output in a program named data. The program takes a few minutes to run.
