Thrash

1.

Experiment with multiple processes and try to infer whether IRIX is enforcing a limit on the amount of memory a single process can allocate, or whether processes can steal frames from each other without restriction.

2.

Run two programs at the same time and try to get them to thrash. Either program alone should terminate in a reasonable amount of time, and use at least a little CPU (like 10% utilization). When you run the two programs at the same time, though, they should both run much longer and their CPU utilizations should go down.

In order to get this part to work, you might have to fiddle with priorities. If you are having trouble, let me know and I will make some suggestions.

Usual rant about reports omitted.
