Pardiso on Mac OS Leopard

cindygr — Tue, 27 May 2008 22:03:59 GMT

Hello,
I'm in the process of porting something from Visual Studio to XCode on the Mac. I have a piece of Pardiso code (below) that works fine on Windows but is crashing (EXC_BAD_ACCESS) on the _second_ time through the solve code (the second call to pardiso in the second round). The results from the first call are fine. As per a previous post, I changed the reporting (iMsgLvl) to zero; that didn't help. I've checked that the first round gives a valid answer. I don't re-initialize the PT data and I don't do any memory frees (problems I fixed to get it working under Windows).

Any help would be appreciated... :)

Do you mean you're using MKL 10.0(.014)? (Check mklsupport.txt in the doc directory). Your problem may have to do with some problems with 10.0 on 32-bit systems with Leopard. If that is your problem, you could try Update 3 which fixed that problem.

Looks like I am running the latest version: Package ID: m_mkl_p_10.0.3.020 Package Contents: Intel Math Kernel Library 10.0 Update 3 for Mac OS* X according to mklsupport.txt. Sigh. --Cindy
