Error in PARDISO ( numerical_factorization) error_num= -987

[Andreas_Fabri__Geome]

Hello,

I try to solve a sparse system with pardiso, using the evaluation version of the Beta of the MKL
on Windows 7, 64.

As I have to enable out-of-core if necessary I initialize the parameters as follows:

m_piparm[0] = 1; // No solver default
m_piparm[1] = 2;
m_piparm[9] = 0;
m_piparm[17] = -1;
m_piparm[20] = 1;
m_piparm[26] = 1;
m_piparm[59] = 1; // out off core if necessary


Here is the trace of the pardiso run. Any help is appreciated, and if necessary
I could dump the sparse symmetric matrix in a file and make it available.

Best regards,

Andreas Fabri


=== PARDISO is running in Out-Of-Core mode, because iparam(60)=1 and there is no
t enough RAM for In-Core ===

Tierry,

We 've checked and reproduced the issue on our side. Actually the problem affects dynamiclly linked libraries. The cause of the problem has been found and will fix soon. I will inform when the fix will available.

thanks agian for the report.

we have already fixed that issue but I am not aware when this fix will available for external customer. in any case - many thanks for the good test case :).

Hi Thierry,

the problem has been fixed in the latest version of MKL 10.2 Update 7. Could you please check if the problem is still there and let us know.
