Can someone explain what is the difference between parameter server and spark ? There's already an issue on this topic https://issues.apache.org/jira/browse/SPARK-4590 Another example of DL in Spark essentially based on downpour SDG http://deepdist.com On Sat, Jan 10, 2015 at 2:27 AM, Peng

Not if broadcast can only be used between stages. To enable this you have to at least make broadcast asynchronous non-blocking. On 9 January 2015 at 18:02, Krishna Sankar ksanka...@gmail.com wrote: I am also looking at this domain. We could potentially use the broadcast capability in Spark to

Hi all, DeepLearning algorithms are popular and achieve many state of the art performance in several real world machine learning problems. Currently there are no DL implementation in spark and I wonder if there is an ongoing work on this topics. We can do DL in spark Sparkling water and H2O but

You are not the first :) probably not the fifth to have the question. parameter server is not included in spark framework and I've seen all kinds of hacking to improvise it: REST api, HDFS, tachyon, etc. Not sure if an 'official' benchmark implementation will be released soon On 9 January 2015

Does it makes sense to use Spark's actor system (e.g. via SparkContext.env.actorSystem) to create parameter server? On Fri, Jan 9, 2015 at 10:09 PM, Peng Cheng rhw...@gmail.com wrote: You are not the first :) probably not the fifth to have the question. parameter server is not included in

I am also looking at this domain. We could potentially use the broadcast capability in Spark to distribute the parameters. Haven't thought thru yet. Cheers k/ On Fri, Jan 9, 2015 at 2:56 PM, Andrei faithlessfri...@gmail.com wrote: Does it makes sense to use Spark's actor system (e.g. via
