Here's the $64,000 question - what is the value of knowing the number of dies on which the cores reside?

Some 3rd party software vendors are now licensing software based on number of sockets instead of number of cores....

which may mean that to comply software has to perform a socket check.

Are they doing this with Java software?

I know that some Java partisans think it's the everything language, but that sort of thing seems much more like systems programming than "write once, run anywhere"-land. In any event, they couldn't use Java directly in a cross-platform way to do that license check; they have to be relying on JNI or some other platform-specific means to get this information.

Please understand that here in clj.programmer I am asking such $64K-questions in a Java-centric way. I never denied that knowing this type of information is useful, I only question how useful in a Java-oriented, cross-platform context.

As to whether this licensing approach works "better" than by the less customer-friendly core count, the more friendly server count, or the commonly offered concurrent usage count, what Everrr! Companies are simply seeking a reasonable metric of usage volume on which to base pricing, as is their right. One could argue in favor of various metrics, but they're all negotiable anyway. Their purpose is merely to give vendor and buyer a common language for the negotiation, is all. As long as the terms are (intelligibly) disclosed negotiations can proceed in good faith.
