subject : problems with the "size.h" file
as can be seen from the manual that , in the size.h file , two kinds of parameters as fellow:
1 ,snx=90,sny=40,olx=3,oly=3 ,nsx=1 ,nsy=1 ,npx=1,npy=1 ;
2 ,snx=45 ,sny=20,olx=3,oly=3,nsx=1,nsy=1,npx=2 ,npy=2 .
I want to know that , the total grid number in X direction is snx*nsx*npx ,in Y is sny*nsy*npy , in the above two cases ,the total grid number are the same , then what is the difference between the two cases ? and , the nsx=1 ,or nsx=2 ,will cause what different influence ? as well as "the npx =1 or npx=2 " ?
someone can tell me what the “tiles” ，“process” exactly mean ? I have read the manual many times ,but I 'm still not clear about it .
many thanks !!!
