Function Documentation

subroutine,public message_passing::add_mp_perf_env ( TYPE(mp_perf_env_type),optional,pointer perf_env )

start and stop the performance indicators for every call to start there has to be (exactly) one call to stop

Parameters:

mp_comm	the mpi communicator
scr	output unit

Note:: can be used to measure performance of a sub-part of a program. timings measured here will not show up in the outer start/stops Doesn't need a fresh communicator

splits the given communicator in group in subgroups trying to organize them in a way that the communication within each subgroup is efficent (but not necessarily the comunication between subgroups)

Parameters:

comm	the mpi communicator that you want to split
sub_comm	the communicator for the subgroup (created, needs to be freed later)
ngroups	actual number of groups
group_distribution	input : allocated with array with the nprocs entries (0 .. nprocs-1)
output	the number of the group the proc belongs to (0..ngroups-1)
subgroup_min_size	the minimum size of the subgroup
n_subgroups	the number of subgroups wanted
group_partition	n_subgroups sized array containing the number of cpus wanted per group. should match the total number of cpus (only used if present and associated) (0..ngroups-1)

Note:: at least one of subgroup_min_size and n_subgroups is needed, the other default to the value needed to use most processors. if less cpus are present than needed for subgroup min size, n_subgroups, just one comm is created that contains all cpus
