|Title||The MPS can't be used to simulate a smaller machine|
|Assigned user||Gareth Rees|
|Description||Developers often work on powerful machines with lots of memory, but want to know how their software will perform on a more restricted machine. The MPS ought to be able to help with this assessment.|
|Analysis||I expect some of this is already possible by creating a limited size arena, but I'm not sure. There are two aspects to this: what happens to performance when, for example, the machine starts to page, but also what happens when allocation actually fails due to lack of resources. Both need to be simulated.|
GDR 2013-05-25: MMQA test function/120  needs a feature like this. RB suggests that "ulimit -v" might do the trick (on Unix, anyway).
