Hi,
Here are few possible queries that can be discussed about multithreaded programming in linux !
1. Can a child process be called as a thread ?
2. Are there multiple ways to create a thread ?
3. Is it possible for the thread to be alive if we terminate the process ? Is it possible for a child process to be alive if we terminate the parent process ?
4. What is the memory layout of a process ?
5. What is the difference between multithreading and multiprocessing ?
6. What is the memory layout of a process with 2 threads ? What is the memory layout a process with 2 child process ?
7. If we declare a variable in the thread handler of 1st thread, will it be accessible accessible to 2nd thread ?
8. If we declare one variable locally in process and another globally in process, which one will be accessible to its threads ? Will those variable be available in child process also ?
9. Is it better to design a multi-threaded application or multi-process application ?
10. When should we need to go for multi-thread design and when should we go for a multi-process design ?
11. What is TLS ?
12. Who schedules the processes and who schedules the threads ?
13. Why process considered to be heavy weight ?
14. What are the contents of PCB ? What are the contents of TCB ?
15. How to ensure that thread1 gets terminated before thread2 ?
16. What will happen if we do not reap the zombie process ?
17. What is the use of zombie process ?
18. What are the various ways to terminate a zombie process ?
19. What is the difference between wait() and waitpid() system calls ?
20. Can two zombie process communicate with each other ?
21. How do you decide on the granularity of the lock ?
22. Is it good to have big lock or small lock ?
23. What will happen if a resource is improperly locked ?
24. What is atomicity ?
25. Where are atomic operations useful ?
26. What is spinlock ?
27. What is the use of PID ?
28. What is a process, thread ? What are the differences between process and thread?
29. If there are 2 sequential fork() calls, how many child process will be there ?
30. What is the use of reentrant function in multi-threaded environment ?
31. What is the advantage of using pthreads or POSIX threads ?
32. What are the various thread models and tell the scenario in which the particular thread model is useful / beneficial ?
33. What are the advantages & dis-advantages of 1:N user level threading (thread model)?
34. What is the difference between userspace threads and kernel space threads ?
35. Will a crash of a thread impact the other thread of the process ?
36. What is the difference between pthread_create() and fork() ?
37. What information is shared between a child process and the parent process ?
38. If a parent has 2 threads , will the child process also inherit or have a copy of those 2 threads ?
39. Why a faulty pointer does not crash a process but that of a thread can corrupt the process / other threads of the process ?
40. What is co-operative multitasking and what is pre-emptive multitasking ?
41. How do avoid race conditions in multi-threading
42. What will happen if you call a sleep() in a process or thread ?
43. Will a parent process be given higher priority compared to child process by the linux scheduler ?
44. What is vfork ?
45. What is the common mode of communication between a parent process and child process ? What are the modes of communication between threads ?
46. Is child process light weight compared to parent process ?
47. What does a fork() call return ?
48. How to terminate a process by programming method ?
49. What are the software models for mulithreaded programming ?
50. What steps are performed during a context switch of a thread and what steps are performed during a context switch of a process ?
