In this case, you have a clear technical difference between a shared library for distribution and for developers. But anyway, I now realize that the MKL is not free on windows anyway, so this is a non problem. cheers, David ___ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion

Let's say Ray's company buys one copy of Intel MKL. This gives them the Intel MKL DLL and link libraries (.libs). Now they compile NumPy and link it against Intel MKL. They can then (as I understand the license agreement, IANAL, etc.) distribute this binary and the Intel MKL DLLs. They may *not* distribute the link libraries. This means that there is no easy way for anyone else to build a new executable that is linked against MKL.

Of course, you better have to make sure the license agreement does permit what you think it says, since your company would bear the responsibility for it as far as I understand it. The one thing which I am not sure about is: say one MKL binary does not work, and say I (or anyone outside your company) build numpy with the MKL ro debug it, can I redistribute a new binary, even if it is just for testing purpose ? cheers, David ___ Numpy-discussion mailing list Numpy-discussion@scipy.org http://projects.scipy.org/mailman/listinfo/numpy-discussion

Given the number of people who've evidently compiledPython/numeric with it I was left wondering why there are no binaries to be found. We've been using the Enthought distros, and our company now has (finally) decided to purchase the ICC and MKL with the intention of compiling for P4 and Core2 targets. The binaries could then go up on the company's web site. Thanks, Ray Schumacher -- No virus found in this outgoing message. Checked by AVG Free Edition.
