Quoting - Gennady Fedorov (Intel)
Michael,
Your original request was regarding dgesv but not dgemm.
1. you reported that you got quasi-infinite loop with a certain size while static linking mode was using.
Its critical for us to understand the cause of this problem, so why first of we d like to know the size
2.if you are interesting in dynamic linking - we can check which *.dll will be call.
3. Is there a service function that returns the cpu id, or instruction sets, etc?
You can use, for example the following routine for checking
int version(void) {
MKLVersion Version;
MKLGetVersion(&Version);
printf("Major version: %dn",Version.MajorVersion);
printf("Minor version: %dn",Version.MinorVersion);
printf("Update number:%dn",Version.BuildNumber);
printf("Product status: %sn",Version.ProductStatus);
printf("Build: %sn",Version.Build);
printf("Processor optimization: %sn",Version.Processor);
}//
You can have something like below:
Major version: 10
Minor version: 1
Update number:0
Product status: Product
Build: 082609.15
Processor optimization: Intel Core 2 Duo Processor
Press any key to continue . . .
+++++++++++++++++++++++++++++
Please pay attention on the line
Processor optimization: Intel Core 2 Duo Processor
If your processor was not recognized by MKLs CPU dispatcher then you will see:
Processor optimization: Default processor

Well, it's a little better now - I added /bin folder to my PATH variable and now it seems to recognize my processor as Core 2 Duo, and it calls MKL_mc.dll. It's also running quite a bit slower than before.
Interestingly, I was looking at my environment variables and PROCESSOR_ARCHITECTURE is set to AMD64. I tried changing it to EM64T, but it changed back automatically when I rebooted the machine. I wonder if this is causing something strange?
The output from the function above that you posted is:
Major version: 10
Minor version: 1
Update number:1
Product status: Product
Build: 082212.12
