Dear All, I will sort out all problems related to project 1 marks on Monday, as I had an eye operation and was on leave yesterday and today. The exam paper is fairly easy, and I am sure you will do well. all the best, Amitava

ANONYMOUS wrote good answer, thanks

No, we haven't started marking the second project.

ANONYMOUS wrote It needs to be consistent so that it is not misused by malicious processes.Complicated interfaces may be easier to manipulate to pass malicious parameters. Also parameter checking is more efficient if they are consistent.

ANONYMOUS wrote Each process starts with three open file descriptors, stdin, stdout, stderr - these will require system calls to open.

ANONYMOUS wrote page size is 2 10 primary page table size is 2 8 There are 2 14 secondary page tables, each entry of the primary page table holds the starting address of a secondary page table. One can bring the secondary page tables on demand (the sec...

ANONYMOUS wrote Sort of, but you can ignore that question. I don't know what Chris meant, may be segmented paging (I haven't explained that).

ANONYMOUS wrote No


SVG not supported 7:25pm Fri 25th Oct, Amitava D.

The page size is 2 10, but what you have written after that does not make any sense. I guess you haven't spent time to understand the lectures. It is impossible to explain here.

I have an eye operation on Thursday, and will be able to answer questions on the help forum only on Friday afternoon. I am here until Wednesday afternoon and you can come and meet me if you need any clarifications.

ANONYMOUS wrote I am trying to release the marks, some marking is still left.

You can give examples of code locality and data locality (e.g., in arrays)


SVG not supported 2:19pm Mon 21st Oct, Amitava D.

That is right, it is up to the examination hall staff to decide, and they may confiscate any typed notes.

ANONYMOUS wrote No, labs are not scheduled this week, as the semester is over. You can ask questions here, or meet me until Wednesday afternoon.

ANONYMOUS wrote multiple declaration of the same variable (name) is an error, you can assume that. We are not overthinking here, make simplifying assumptions, state those assumptions in a file, and you will be fine.


SVG not supported 3:41pm Fri 13th Sep, Amitava D.

Where did you get this ml syntax from? I haven't seen this.


SVG not supported 3:40pm Fri 13th Sep, Amitava D.

There is no need to complicate matters. Assume that there is no nested function, and that the generated code can be compiled without -Werror


SVG not supported 3:39pm Fri 13th Sep, Amitava D.

ANONYMOUS wrote You can add a print statement in the ml file if you want something to be printed. Submit that modified ml file mentioning that you have added a print statement.


SVG not supported 3:37pm Fri 13th Sep, Amitava D.

ANONYMOUS wrote I don't understand the source of this confusion. I have sent an email (and you can clearly quote that in case of any dispute) aand what I wrote there is correct. I cannot go on sending emails recursively and validate ad infinitum.


SVG not supported 3:36pm Fri 13th Sep, Amitava D.

ANONYMOUS wrote I didn't have much time to look at the project carefully. However, main() is also valid in C, without any parameters like argc and argv


SVG not supported 3:30pm Fri 13th Sep, Amitava D.

ANONYMOUS wrote You should make simplifying assumptions, and clearly write those assumptions in your report. I am not sure whether a report was required in the original project description, but you can submit a report that lists all the assumptions y...

ANONYMOUS wrote C accepts variable number of parameters in functions, so any parameter mismatch will be tolerated by the C compiler. You need not check the correctness of parameters.


SVG not supported 3:27pm Fri 13th Sep, Amitava D.

Use gcc without -Werror.

I don't know what Chris had mind, it could be a trick question (note the 'always be true'). Suppose I write a complete C code with a main() and do not call this function?
