ifort with math karnel library not working

[Natu_D_]

Hi all,

I installed parallel_studio_xe_2015_update3 on fedora 22 operating system. Although it activated and installed successfully but

it is not working properly. That is when i run a fortran90 code which include some lapack subroutines with this command for compilation-

ifort -mkl example.f90

 It compiled successfully. but as soon as i am going to execute this code with ./a.out, i found that the code stopped suddenly without

completing its loop. For example if my loop is from x=0 to x=7, then it stopped at some random value in between x=0 to x=7.

So i don't know the reason behind this cause. If anybody have any idea about this problem then please help me.

Thanks....

What do you mean by "stopped"? Did the program exit prematurely, or did it freeze up? Without seeing the source code, it is hard to advise you about what to do.

To test whether you have a functioning software installation, build one of the test problem source codes provided with MKL and run it.

Hi mecej

Thank you for your kind response. By 'stopped' means, the program freeze up.

Like at first, it takes almost 398% of c.p.u out of 400% c.p.u but after two or three hours, it comes down to 0%.

But i checked that the same code is running well in my older version of parallel_studio_xe that is  Intel(R) Fortran Intel(R) 64 Compiler XE for applications running on Intel(R) 64, Version 14.0.2.144 Build 20140120

Are you able/willing to provide the example.f90 source code so that the problem may be reproduced by others, since that is the usual way of finding the root cause of a problem? Have you considered upgrading to Parallel Studio 16.0, since it is possible that your bug may have been one of those that were fixed in going from 15.0.3 to 16.0?

Hi

Thanks a lot. I downloaded and installed the parallel studio 16.0 and it is working well in the newer version. Can you please tell me how can i upgrade the 15.0.3 to 16?

By installing the Parallel Studio XE 2016 (16.0 compiler) you have in effect "upgraded". There's nothing more needed really. Both the PSXE 2015 Update 3 (i.e. 15.0.3) and PSXE 2016 (i.e. 16.0) can reside on your system simultaneously. If you no longer wish to have the 15.0.3 release present, then you can use the uninstall.sh (found under the default path: /opt/intel/composer_xe_2015.3.187/) to remove that release.
