pvm_gather - A specified member of the group receives messages
from each member of the group and gathers these messages into a
single array. C int info = pvm_gather( void *result, void *data,
int count, int datatype, int msgtag, char *group, int rootginst)
Fortran call pvmfgather(result, data, count, datatype, msgtag,
group, rootginst, info) result On the root this is a pointer to
the starting address of an array datatype of local values which
are to be accumulated from the members of the group. If n if the
number of members in the group, then this array of datatype
should be of length at least n*count. This argument is
meaningful only on the root. data For each group member this is
a pointer to the starting address of an array of length count of
datatype which will be sent to the specified root member of the
group. count Integer specifying the number of elements of
datatype to be sent by each member of the group to the root.
Integer specifying the type of the entries in the result and
data arrays. msgtag Int
