My program is compiled with the latest revision of IVF 2015 Composer edition. It makes use of a number of mkl functions including CGEMM and ZGEMM. The code involving the mkl functions is unchanged and has worked flawlessly for many years through numerous versions of IVF and CVF before that.
But since compiling with IVF 2015 a problem has shown up. When calling CGEMM or ZGEMM, the program abruptly ends without any message. Compiled for debug, it also shows nothing. It only happens above a certain problem size, and the two users reporting the problem have AMD processors, one an FX8320 and the other an A10-4500M. My program is compiled as a 32 bit application so runs as such on either 32 or 64 bit systems. Both users with problems are using Windows 7.
I've updated my IVF 2015 to the latest revision, and out of curiosity I furnished one customer with mkl dlls from an earlier revision of 2015 and from 2013 SP1 to try. No help, although all were run with the basic program compiled with 2015 and its associated libraries.
Is there some compiler option I need to use in order to gain compatibility with these processors or to isolate the problem? I'm assuming that the problem is related to AMD processors since the two people out of several hundred successful users both have them -- but I don't know this for sure.
I'll be glad to furnish any other information that might be helpful in solving this.
Thanks!
