Hi Liquan,
There is some working being done on implementing linear algebra algorithms
on Spark for use in higher-level machine learning algorithms. That work is
happening in the MLlib project, which has a
org.apache.spark.mllib.linalgpackage you may find useful.

Hi
I am currently implementing an algorithm involving matrix multiplication.
Basically, I have matrices represented as RDD[Array[Double]]. For example,
If I have A:RDD[Array[Double]] and B:RDD[Array[Double]] and what would be
the most efficient way to get C = A * B
Both A and B are large, so it w
