For instance in the latest hudson build, I see this: Running org.apache.mahout.math.jet.random.NormalTest Tests run: 4, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 231.75 sec
But on my own machine, I see this: Running org.apache.mahout.math.jet.random.NormalTest Tests run: 4, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.89 sec I am pretty sure that this means that the uncommons math package will still waiting for /dev/random. I don't think that switching to SecureRandom has helped. In fact, I think that SecureRandom is probably doing the same sort of entropy collection as the old seeding policy used. It is also somewhat puzzling to me that these tests aren't using completely deterministic seeds yet. That was a bit part of what Sean just did so I will look at that as well.
