10. During your exciting interview at MIT, you find that they seem to like distributed shared memory. They ask you the following question involving 5 processes P1-P5 in a distributed shared memory system using invalidate. Process P3 wants to write a page. In each of the following cases, say what is the series of operations that needs to happen for P3 to be able to write (warning: there be tricks below!) -- You cannot use the Web for this question. If the setup seems wrong to you, you should point out ALL errors in it. a. P3 is the owner of the page, and is the only one holding it (in Read Mode) b. P3 is holding the page in Read mode and P4 is holding it in Write mode and P3 is the owner c. P4 is the owner and is holding the page in a Write mode d. P1 and P2 are each holding the page in a Write mode, and P3 is the owner e. P1, P2, P3 are each holding the page in a Write mode, and P3 is the owner f. P1, P2 and P3 are currently holding the page in Read mode, P2 is the owner g. P2 and P4 are holding the page in Read mode, and P4 is the owner h. P3 and P4 are both holding the page in write mode i. P1 is holding the page in write mode j. P4 and P5 are each holding the page in a Read mode, and P4 is the owner
