Hi Jeremy, Can you try doing a comparison of the Scala ALS code (https://github.com/apache/incubator-spark/blob/master/examples/src/main/scala/org/apache/spark/examples/SparkALS.scala) and Python ALS code (https://github.com/apache/incubator-spark/blob/master/python/examples/als.py) from the Spark repo?
This might be the easiest way to compare Scala+Colt vs Python+Numpy on Spark! Both contain sparse matrix manipulation and multiplications. If someone already has a small Spark cluster (even standalone) already setup, please let us know about how this fares. I'll try setting up Spark on a few nodes next week.
