Is it wise to access read-only data from multiple threads simultaneously?

Question

I have an application that I\'m trying to make multithreaded. Each thread will access a large chunk of read-only data.

Is is okay if multiple threads access the data

Answer 1

If the data is truly read-only for the duration of the multi-threaded access, then no synchronization is necessary.

Answer 2

Yes, that's fine.

You shouldn't have any problem.

Answer 3

If the data is read-only for the lifetime of all the threads that read it, then yes, it's perfectly fine to read without synchronization.

Answer 4

If the data is fixed before any of the reading threads start, then yes, it's OK.
