"Frame reclaming" algorithm clarification. | |
1. The "Frame reclaiming" algorithm as originally (and clearly) defined in HW5 was supposed to go over all the pages every time a frame should be freed, update their counters and reference bits and only then release a frame. 2. Due to a misunderstanding, the FAQ changed the original definition to the following: "Frame reclaiming" algorithm first seeks a page that can be released and only if no such page was found it goes over all pages to update the "counter" and "reference" fields. In both versions, the actual evacuation of a frame is done only when the frame is assigned to a new page. We will accept both versions. Please clearly state which version of the algorithm you implemented. Note that the answer to Q2.4 depends on the version of the algorithm. We have attached test files that show the difference between the two algoritms. Files are: lruinput2.txt , lruinput7.txt : same access sequence with different *k* parameter. lruinput2.txt - LRU-2. lruinput7.txt - LRU-7. out1_2.txt ,out1_7.txt : output according to original version. out2_2.txt , out2_7.txt : output according to "new" (wrong) version. We won't publish big tests examples since then there will be no point in automatic check. For test purposes you can use this random test generator ("testGenerator.c"). |

Corrections to HW1 | |
Corrections to HW1 - file that you should use with VMWare is 'linux-234120.vmx' and not 'linux.vmx' - bzImage location is '/usr/src/linux-2.4.18-14custom/arch/i386/boot/' and not '/usr/src/linux-2.4.18-14custom/' - for printing jiffies you should use '%ld' and not '%lld'. |
