Random Walk of Life

The Road goes ever on and on, down from the door where it began. Now far ahead the Road has gone, and I must follow, if I can, Pursuing it with eager feet, until it joins some larger way, where many paths and errands meet. And whither then? I cannot say… — J R R Tolkien, Lord Of the Rings

Opening Mood: Good Morning! Gosh, it’s already Good Afternoon.
Opening Song: Swadesh (title song)

After spending two consecutive nights going through the implementation of Read Copy Update (RCU), both classic and preemptible, and trying to find a flaw in vain, I am kind of exhausted. And very impressed. RCU is twisted, yet so simple. I read elsewhere, that maybe the human mind wasn’t cut out for designing parallel algorithms. We tend to think in a more sequential fashion. (Probably which is why folks back in college, find linked list algorithms simpler than an RB tree!!)

I guess RCU is one of the exceptions to this theory!

Anyway, recently I came across this blog which I highly recommend. Especially this post.

Cheers to a Happy Weekend ahead!!!
