Groups are collections of parallel processes

Provided Methods

Group union

Constructs a new group that contains all members of the first group followed by all members of the second group that are not also members of the first group.

Standard section(s)

6.3.2

Group intersection

Constructs a new group that contains all processes that are members of both the first and second group in the order they have in the first group.

Standard section(s)

6.3.2

Group difference

Constructs a new group that contains all members of the first group that are not also members of the second group in the order they have in the first group.

Standard section(s)

6.3.2

Subgroup including specified ranks

Constructs a new group where the process with rank ranks[i] in the old group has rank i in the new group.

Standard section(s)

6.3.2

Subgroup including specified ranks

Constructs a new group containing those processes from the old group that are not mentioned in ranks.

Standard section(s)

6.3.2

Number of processes in the group.

Standard section(s)

6.3.1

Rank of this process within the group.

Standard section(s)

6.3.1

Find the rank in group other' of the process that has rankrank` in this group.

If the process is not a member of the other group, returns None.

Standard section(s)

6.3.1

Find the ranks in group other' of the processes that have ranksranks` in this group.

If a process is not a member of the other group, returns None.

Standard section(s)

6.3.1

Compare two groups.
