5 Reference for functions

5.1 g6_setmccount

int g6_setmccount(int mccount)

subroutine g6_setmccount(mccount)
integer mccount

This function tells the GRAPE-6 interface library how many hosts are used in parallel. Using this information, the library determines what configuration should be used in M-mode. This function should be called before g6_open.

5.2 g6_set_ijp_mode

int g6_set_ijp_mode(int clusterid, int mode)

subroutine g6_set_ijp_mode(clusterid,mode)
integer clusterid, mode

When called with mode=0, this funnction puts GRAPE-6 to the state to receive $i$-particles and other commands. When mode=1, it puts GRAPE-6 to the state to receive $j$-particles. In usual cases, this function is called internally from other interface functions and it is not necessary for an application program to call this function

explicitly.

5.3 g6_set_cbjpmode

int g6_set_cbjpmode(int clusterid, int mode)

subroutine g6_change_cbjpmode(clusterid,mode)
integer clusterid, mode

When called with mode=0, this function puts GRAPE-6 to N-mode with mode=1, to M-mode.

5.4 g6_setup_njdata

int g6_setup_njdata(int clusterid, int nbody)

subroutine g6_setup_njdata(clusterid,nbody)
integer clusterid, nbody

This function must be called before the number of particles you send to the memory (2nd argument of firsthalf/lasthalf) changed. This function must be called only when cbjpmode=1 and ijp_mode=1.
