[petsc-users] valgrind errors.

[(Rebecca) Xuefei YUAN]

Dear Jed,

This makes a lot of sense!

I made the following change:


	ierr = PetscMalloc((info.mx)*(info.my)*sizeof(FieldOther),  
&fieldother);CHKERRQ(ierr);

and the values of iFirst, iLast, jFirst, jLast in one single processor is from

	iFirst = info.xs;	iLast = info.xs + info.xm - 1;	jFirst =  
info.ys;	jLast = info.ys + info.ym - 1;


where
	ierr = DAGetLocalInfo((DA)dmmg->dm,&info);CHKERRQ(ierr);

.

However, I still have the same errors as before in valgrind.

I think it is better for me to do the second way of cloning DA to set  
up these temp arrays.

More later.

Thanks so much!

Rebecca
