[Beowulf] METIS Partitioning within program

Amjad, 


Have you thought of using the system call: 


"system(const char *string);" 


Type "man system" for a description. You can pass any string 
to the shell to be run with this call. For instance: 


system("date > date.out"); 


would instruct the shell to place the current date and time 
in the file date.out. If the command you wish to run changes 
cyclically y ou would have to manage the changes from inside 
the program. I am assuming a C program here. 


Regards, 


rbw

Subject: [Beowulf] METIS Partitioning within program 

Hi all, 

For my parallel code to run, I first make grid partitioning on command line then for running the parallel code I give hard-code the path of METIS-partition files. It is very cumbersome if I need to run code with different grids and for different -np value. Please tell me how to call METIS partitioning routine from within the program run so that whatever -np value would be we are at ease. 

THANKS A LOT FOR YOUR ATTENTION. 

Regards, 
Amjad Ali.
