Size of memory used by a program
Hello,

Here is a portion of my code:
Code:
a=(int *) malloc(dim*dim*sizeof(int));
b=(int *) malloc(dim*dim*sizeof(int));
c=(int *) malloc(dim*dim*sizeof(int));

for(i=0;i<dim;i++)
 for(j=0;j<dim;j++)
  c[i*dim+j]= rand();


for(i=0;i<dim;i++)
 for(j=0;j<dim;j++)
      b[i*dim+j]=rand();

for(i=0;i<dim;i++)
 for(j=0;j<dim;j++)
  a[i*dim+j]=0;


for(i=0;i<dim;i++)
 for(j=0;j<dim;j++)
  for(k=0;k<dim;k++)
  
{
 a[i*dim+j]+=b[i*dim+k]*c[k*dim+j];
}

How can i get the size of the data used by my program?

Thank you in advance.
Best Regards.

gmk_ub2

gmk_hy(1)						       Scotch user's manual							 gmk_hy(1)

NAME

       gmk_hy, gmk_m2, gmk_m3, gmk_ub2 - create source graphs

SYNOPSIS

       gmk_hy [options] dim [ofile]

       gmk_m2 [options] [-gcfile] dimX dimY [ofile]

       gmk_m3 [options] [-gcfile] dimX dimY dimZ [ofile]

       gmk_ub2 [options] dim

DESCRIPTION

       The gmk_* programs create source graph files for some common, regular topologies.

       gmk_hy creates a hypercube of dimension dim.

       gmk_m2 creates a 2D regular grid of dimensions dimX and dimY.

       gmk_m3 creates a 3D regular grid of dimensions dimX, dimY and dimZ.

       gmk_ub2 creates an unoriented de Bruijn graph of dimension dim.

OPTIONS

       -b base
	      For gmk_m2 and gmk_m3 only. Output graphs with base value set to base. Default value is 0.

       -e     For gmk_m2 only. Build a 8-neighbor grid rather than a 4-neighbor grid.

       -gcfile
	      For gmk_m2 and gmk_m3 only. Output graph vertex coordinates (that is, geometry data to be used by gout(1)) in file cfile.

       -h     Display some help.

       -t     For  gmk_m2  and	gmk_m3	only. Create torus graphs, that is, graphs such that there exist loop edges between vertices of rank 0 and
	      (dim-1) in every dimension.

       -V     Display program version and copyright.

EXAMPLE

       Create a 5x7 grid along with its geometry:

	   $ gmk_m2 5 7 -g/tmp/m5x7.xyz /tmp/m5x7.grf
