Running paraview parallel on windows 7
 
Dear users,
Hello everyone. Currently I am handling a lot of data in VTK format with paraview in windows 7. To be specific the number of cells is around 1.5 millions. Although I have a very powerful graphics card, my paraview is operating very slow. I guess the problem is arising due to the usage of the processor. Is anything like mpirun available on windows 7? If so then I think I could possibly use it and make paraview faster. Could anyone shade some lights on this matter? I would appreciate your help.
Thank you.

Greetings Naruto,

ParaView provides a neat feature to activate (by default) the usage of multiple cores on a single machine.
It's accessible through the menu "Edit -> Settings", then in the "General" item on the tree on the left and then it's the option "Use Multi-Core". To its right you can choose the number of cores.

Keep in mind that "the more, the merrier; but too many makes a mess" ;)

Best regards,
Bruno

Dear wyldckat

I want to use paraview, using multicore, on my computer (not server). I followed your comment. I have checked
Multicore support/Enable Auto MPI

However when I load my case, it does not use multi processors. Is there any thing else I have to take care?

I should note that I have installed paraview simply from "http://www.paraview.org/download/

Greetings Amir,

Unfortunately back then I either forgot to write it down or wasn't aware of another requirement: the data reader must also support parallelization.

And there are only a few data readers in ParaView that support this, for which an old list exists here: http://www.paraview.org/Wiki/ParaVie...a_Distribution

I believe it is also possible to open OpenFOAM cases in parallel as well, but it requires using the internal reader (file extension ".foam") and the case must also be decomposed and the respective case loading option must be used.

Best regards,
Bruno
