Re: Page Rank Calculation

Hallo Matthias,

herzlichen Dank für die Rückmeldung.....
It was a really nice explanation. But one question is that why (cira ~12 round) does it need? Can I finish after 5,6 or any random number? Is there any rules for the round?

Dank im Voraus

Straggler?

Hallo Zusammen?

As far as I could figure out that Straggler is the degradation of performance. isn't? Because performance is based on completion. So, Either re-execution or faulty Hardware might be propagated, Straggler. Is it correct? Is there any other reason for Straggler?

Dank im Voraus

Re: Methodolgy of Teaching System totally disagree

Dear Meichholz, Thanks for the reply. I am afraid that I have to strongly differ on your some points. '' Besides this, this course is targeted at master students and we assume that you are already familiar with Java. What we want to teach you, is the concept behind the MapReduce programming model, w...
