olà everyone,

I have a problem with a UDF that i'm trying to use on parallel. When using it in the serial mode, it's ok. But i don't understand how to use the commands such as "#if RP_HOST .... and also the commands such as "host_to_node"...ecc.
My udf is as follows - i can't send it for "confidential reasons" - so i will try to be as clear as precise as possible :

-----------------------------------------------
#include "udf.h"
#include "math.h"
#include "stdio.h"
#include <stdlib.h>
#include <unistd.h>
#include "para.h" (is this one useful? )

#define M_PI 3.14159265....

int **holewall;
int *indicet;


DEFINE_ON_DEMAND(calc_holewall)
- list of variables...
- reading of the data file

- other variables :
meth = (Thread **)malloc(sizeof(Thread *)*idotmax);
holewall = (int **)malloc(sizeof(int *)*idotmax);
- program that loops on c_loop

end of DEFINE_ON_DEMAND

DEFINE_SOURCE(xmom_source,c,t,dS,eqn)
-list of variables
- program

the same for ymom and zmom.
------------------------------------------------
I don't know how i can understand what the host or the nodes do...

If someone as any clue for me...i can be more precise if needed.

Thank you very much.
