Subject RE: Hama task on multiple cores
Date Wed, 22 Jul 2015 03:19:36 GMT

Hama framework spawns one JVM for each task. So, it depends on whether JVM 
uses multicores.

If you wanna benchmark on single machine, I recommend you to use Hama local 
mode (multi-threading). :-)

Subject: Hama task on multiple cores

I am trying to do some performance comparisons between MATLAB and HAMA
implementation of same thing. MATLAB provides some functions to do parallel
execution on multiple cores.

Hama is already parallel but I do not understand the relation between Hama
tasks and cores on a computer.

For example, if I have a machine with 4 cores and I want to open up 4 Hama
tasks, where will Hama open them ? Each task on each core ?

Or If I have 4 cores but I have 10 tasks, how the tasks will be distributed
on cores ?
