Subject [jira] [Commented] (HAMA-500) Add random matrix generator.
Date Fri, 13 Apr 2012 09:34:15 GMT


Mikalai Parafeniuk commented on HAMA-500:

I have submitted first version patch for this issue. It doesn't have the option
to produce symmetric matrices yet. This class will be refactored later
to use data structures, which I want to create for linear algebra package.
Anyway I have a set of question about this patch.
1) Is this algorithm is something you have expected?
2) Have I choose the right command line format?
3) Is exception handling appropriate for Hama?
4) Is documentation style appropriate for Hama?

> In this issue, we add random matrix generator to produce large data sets that can be
used for graph or matrix examples. This can be implemented using BSP job.
> It'd be nice if sparsity, symmetry, and size can be configurable via the command line.
