MPSS version confusion 3.1.x vs 2.1/gold_update_3_5...

MPSS version confusion 3.1.x vs 2.1/gold_update_3_5...

Maybe it's just me, but the MPSS versioning seems potentially confusing.  I was recently updating my Compiler/VTUNE stuff from the "registration center" and saw that there's a new MPSS gold_update3_5 that just came out.  Reading through the readme-en.txt I start seeing references to MPSS 2.1.6720-23 and scratching my head.  Looking through my existing 3.1.2 readme it looks like 3.1.2 actually had newer stuff.  So I start poking around. Going through the software.intel.com site I get to the MPSS page which differences the 2.1 vs. 3.1 releases and it looks like what I really want is 3.1.4.  I guess if you pay attention it all makes sense, but I very nearly "updated" from 3.1.2 to gold_update3_5 (i.e. 2.1.6720-23) which probably wouldn't have been pretty. 

Maybe this will save someone else some heartburn?

P.S. Might be nice if there were some forum tag pulldowns for: Software Products= MPSS and/or Technology= MIC and such.

Hi Craig,

Sorry for the confusion. Let me try to clarify a bit.

There are currently two streams of MPSS for Linux we have to maintain:
- MPSS 2.1 (also referred as Gold Update x)
- MPSS 3.1.x

People who use to stream MPSS 2.1 can download the version mpss_gold_update_3.2.1.6720-21 (Gold Update 3) from http://software.intel.com/en-us/articles/intel-manycore-platform-software-stack-mpss  or get the latest version mpss_gold_update_3.2.1.6720-23 (Gold Update 5) from http://registrationcenter.intel.com

People who use the stream MPSS 3.1.x can get the latest MPSS 3.1.4 from http://software.intel.com/en-us/articles/intel-manycore-platform-software-stack-mpss 

Hope this helps. Thank you.

I'm seeing both the 3.1 family, as well as the "gold updates" (e.g. 2.1 family) in my registrationcenter.intel.com subscriptions once I select "Intel MPSS for Linux* and then explore the list of available updates/build numbers.   The naming confusion is unfortunate.  Sorry.
