Debugging an OpenMP code

[Jack_S_]

Hi all,

I haven't seen a coherent/official OpenMP debugging post by the Intel guys.

How can I debug an OpenMP Fortran code with idb ? Are there any compilation flag(s) required in order to ''serialize'' the code first ?

Any suggested manual/links that you know off ?

Appreciate your time and your answers.

Best regards,

Jack.

Dear Jack,

other then enabling symbol info in your code there is no need for execuation serialization or anything like it with the old Intel Debugger 13.0 (IDB).

In the debugger user guide (https://software.intel.com/sites/products/documentation/doclib/stdxe/2013/composerxe/debugger/user_guide/) I would refer to the chapters "Debugging Parallel Applications", especially the entries on "Working with Threads" and "Debugging Multi-Threaded Applications".

There are special notes on

• Finding Bugs in OpenMP* and Serial Code  https://software.intel.com/sites/products/documentation/doclib/stdxe/2013/composerxe/debugger/user_guide/GUID-B555131E-9008-46EF-BC0C-465E157DF7DC.htm

Please let me know if this answers your question or if you would like to ask about a specific use that you would like to discuss in mor detail.

I will gladly try to help.

Thanks, Rob
