Multi-threading in SAS 9.3?

[hanson4022]

I've been browsing around on google and here seeing some discussion about how SAS utilizes multiple CPU cores. It seems like SAS has been adding more options for multi-threading and procedures that use it by default in the last few versions. However, I haven't been able to find a recent resource for SAS 9.3 that spells out especially what procedures support it. Has anyone stumbled across recent documentation like this? There are a few papers out there from a few years ago, but since they're for older versions of SAS I can't be sure what current versions support.

What I'm ultimately hoping is that a few of my commonly used procedures, such as PROC LOGISTIC, have the option to use it. In many cases I do regressions using very large combinations of by variables and output all the results to a single dataset showing model fit for each variable combination. That takes quite awhile, but it seems like a very opportune type of analysis to take advantage of multi-threading since you should be able to run all of the analyses of the by variables in parallel. Unfortunately I'm away from my computer with SAS installed for awhile, so I can't test it out for myself right now. I'm looking into getting an 8-core processor soon, so I just overall wanted to see how much I would be able to utilize all of it.

Hi:

  Have you looked in the R&D Scalability community area? For example:

Scalability and Performance Success Story

        Scalable SAS Procedures     

  In those topics, there is an email for specific scalability suggestions if you want to check on LOGISTIC, specifically. But I only see these 4 SAS/STAT procedures listed.
