Subject Do spark works on multicore systems?
Date Sat, 08 Nov 2014 22:17:45 GMT
I am a Spark newbie and I use python (pyspark). I am trying to run a program
on a 64 core system, but no matter what I do, it always use 1 core. It
doesn't matter if I run it using "spark-submit --master local[64] run.sh" or
I call x.repartition(64) in my code with an RDD, the spark program always
use one core. Has anyone experience of running spark programs on multicore
processors with success? Can someone provide me a very simple example that
does properly run on all cores of a multicore system?
