I’m opening multiple files and processing them, one line at a time. The files contain tokens separating the data, such that sometimes the processing of one file may have to wait for others to catch up to that same token.

I was doing this initially with only one thread and an array indicating with true/false if the file should be read in the current iteration or if it should wait for some of the others to catch up.

Would using threads make this simpler? More efficient? Does Ruby have a mechanism for this?

    I’m not sure if using threads in ruby is beneficial. Recently I’ve written and tested an application which was supposed to do parallel computations, but I didn’t get what I expected even on quad core processor, it performed computations sequentially, one thread after another. Read this article, it has discussion about threads scheduling, it may turn out that things haven’t changed at least for original ruby.
