Is it possible to parallelize SVD computing, using for example Hadoop\'s MAP REDUCE?开发者_StackOverflow社区
I\'m confused about Twisted threading.开发者_如何学C I\'ve heard and read more than a few articles, books, and sat through a few presentations on the subject of threading vs processes in Python.It ju
I\'m trying to get my head around an issue with the theory of implementing the PageRank with MapReduce.
Please bear with me, I\'m开发者_StackOverflow pretty new to the whole CouchDb stuff. The db looks like:
When running Hadoop in EC2, I seem to have two options: A: Manage the cluster myself, using the EC2-specific shell scripts that come with Hadoop.
Upon hearing that the scientific computing project (happens to be the stochastic tractography method described here) I\'m currently running for an investigator would take 4 months on our 50 node clust
I am working on the parallelization an algorithm, which roughly does the following: Read several text documents with a total of 10k words.
My map function looks like this: map = function() { day = Date.UTC(this.TimeStamp.getFullYear(), this.TimeStamp.getMon开发者_如何学Cth(), this.TimeStamp.getDate());
I have a requirement that my mapper may in some cases produce a new key/value for another mapper to handle.Is there a sane way to do this?I\'ve thought about writing my own custom input format (queue?
