| 40 | <P> | ||
| 41 | |||
| 42 | By now you should have some familiarity with the inner workings of | ||
| 43 | Pintos. Pintos can properly handle multiple threads of execution with proper | ||
| 44 | synchronization, and can load multiple user programs at once. In this assignment, | ||
| 45 | you will improve the memory management of Pintos. | ||
| 46 | </P> | ||
| 47 | <P> | ||
| 48 | |||
| 49 | This assignment requires user programs (and in particular argument passing, | ||
| 50 | which you implemented in project 0) to work. You will continue to handle | ||
| 51 | Pintos disks and file systems the same way you did before | ||
| 52 | (see section <A HREF="pintos_2.html#SEC24">2.2.2 Using the File System</A>). | ||
| 53 | </P> | ||
| 54 | <P> | ||
| 55 | |||
| 56 | The documentation for this assignment will be released when Project 2 | ||
| 57 | is about to start. | ||
