Crash in the Cluster Sparse Solver Windows-64

[Fanny_D_]

Hi,
 

I am using the Cluster Sparse Solver on Windows 64 (Parallel Studio xe 2016.0.110) on a symmetric indefinite matrix and the numeric factorization crashes for 2 MPI process and 4 OpenMP threads. No specific error message is displayed.
 

In case of 1 or 4 MPI processes with 4 OpenMP threads the calculation is running without crash.
 

My C++ program is compiled with the Microsoft Visual Studio C++ compiler (Visual Studio 12 2013 18.0.31101.0) and is linked with the following libraries:

- impi.lib (Intel MPI 5.1.1.110 of Parallel Studio xe 2016.0.110)
- mkl_intel_lp64.lib;mkl_core.lib;mkl_intel_thread.lib;mkl_blacs_intelmpi_lp64.lib;libiomp5md.lib (MKL of  Parallel Studio xe 2016.0.110)
 

My computer has 32Go (RAM) and 2 processors (Intel(R) Xeon(R) CPU E5-2687W v2 @ 3.40GHz).
 

Please find in attachment my program and associated files.
 

Thanks in advance for your help.

Funny, what are the symptoms of this issue? Have you checked the error code returned by Pardiso. It seems your system doesn't have enough RAM available.

I have no specific error code.

Please find the output logs for 1 and 2 MPI process.

Best regards.

Funny, could you please check the latest MKL 11.3 update 2. The similar problem has been fixed after 11.3.0 release. Please let us know how it will work. thanks.

The MKL 11.3 Update 2 solves the problem.

Thanks for your help!
