Date Mon, 16 Mar 2009 00:53:18 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hama Wiki" for change notification.

The following page has been changed by udanax:

  - A map task receives a blockID n as a key, and two sub-matrices of A and B as its value
  - Reduce task computes sum of blocks
+ -- ''If A stored on Hbase and we collect the B to A, we can reduce once the mapreduce job
--Edward ''
  === Find the maximum absolute row sum of matrix ===
  Matrix.Norm.One is that find the maximum absolute row sum of matrix. Comparatively, it's
a good fit with !MapReduce model because doesn't need iterative jobs or table/file JOIN operations.
