What is the value of High-Performance Analytics

Many organizations struggle with identifying the business value of accelerating the performance of analytics. Can Mark describe what the business value will be to UnitedHealthcare of accelerating the time of the process from 4 hours 15 minutes to 10 seconds, and how it will impact on the business?

Right -- because a run time of ten seconds is great, but you have to consider time to load from Greenplum to HPA when weighing in-memory analytics versus in-database analytics (which don't require the extra load).

Usually people love to talk about stuff that works well, so the load time must be an issue.

Whoops! Missed this earlier. This OptimumInsight project looks fascinating, at a quick flip through the slides. I have to set aside some time to give it my full attention!

@thomaswdinsmore -- Mark declined going into further detail, but I would assume that, yes, data load time is a consideration!

Any response to the last two questions?   It's curious that nobody wants to talk about the time to load data from Greenplum to HPA -- that strikes me as a material consideration when evaluating a co-located approach.

It's production work, not a test.  Here's a link.  OptumInsight is a unit of UHG

@thomasedinsmore, while I'm checking in with Mark on these answers, maybe you could briefly share the results of the other UHG high-performance test?

Beth,

Thanks for the response.  Two follow-up questions:

(1) How much time did it take to load the data from Greenplum into HPA's memory?

(2) Did you test any larger problems?  There is a group inside UHG that successfully run predictive analytics on billion-row datasets (using alternative technologies).

@thomaswdinsmore, I've checked with Mark Pitts, and here are his responses: 

(1) UHG has not yet purchased the product. 


(2) The load rate referenced in the article -- is that the time needed to load raw data into EMC Greenplum, or the time needed to load data from Greenplum into HPA's memory?
    - The load rate in the article is the time to load raw data into the EMC Greenplum DCA.
  

(3) The analysis on four million rows that takes four hours in the current state environment -- what analysis did Mr. Pitts's team test, and what environment does this currently run on?
    This was one of many tests we ran.  This one was a simulation written in DS2 that ran an algorithm that was computationally intensive and I/O intensive - we wrote it intentionally to put the DCA through it's paces.  The 4-hour run for the same algorithm ran on a dedicated, 16-core SMP Unix server - with dedicated meaning that nothing else was running on the server during the test.

Several questions about this story.

(1) Did Mr. Pitts' firm actually license the product for production?  The article simply refers to a POC.

(2) The load rate referenced in the article -- is that the time needed to load raw data into EMC Greenplum, or the time needed to load data from Greenplum into HPA's memory?

(3) The analysis on four million rows that takes four hours in the current state environment -- what analysis did Mr. Pitts's team test, and what environment does this currently run on?
