HPC 101: Concurrency, Parallelism and You (Part 2)

[siuwilly]

Good job Doug! I like your examples. Not everyone is a computer scientist, so your approach is very appropriate. In fact, a vast minority of the people learning this stuff today are computer scientist 'type of folks'. Thanks! I like your other videos, too.

Seriously WTF.

Hey guys you getting me baffeled here. I donot see the cosecutivety here. the continuation of the videos...

concurrency and parallelism - douglas speaking/me watching

douglas: sniffing, rambling, swallowing, assuming poorly &

me: yawning, dozing, waiting, wishing for some content &

end result:

me wasting 5+ minutes (after i figured out there was no content in the part 1)

What a waste of time! This so called "professor" needs almost ten minutes to just SAY, certainly NOT EXPLAIN, that concurrent is not a synonym for parallel. Boy, what an achievement! And he keeps on and on taking about his silly markers. Sheer rubbish!

Would have never expected something as bad from a high quality, scientifically sound and pedagogically excellent magazine as Linux Magazine is. Please improve, or just change the speaker.

You didn't define. Concurrent means happening at the same time. You may have 3-4 processes that depend to a degree on one another running concurrently. (separate, even isolated)

If a process would benefit, it can be paralleled. Multiple threads or instances of the (one) process my run separately (concurrently!) to conclude more swiftly.

Not all math can run parallel (so far as legitimate results) it often has to run linearly. The quality of results is the determinant, parallel or not..
