CLOG_csync(4)
NAME
CLOG_csync - synchronize clocks for adjusting times in
merge
SYNOPSIS
#include
#include "mpe.h"
void CLOG_csync( root, diffs )
int root;
double diffs[];
This version is sequential and non-scalable. The root pro-
cess serially synchronizes with each slave, using the first
algorithm in Gropp, "Scalable clock synchronization on dis-
tributed processors without a common clock". The array is
calculated on the root but broadcast and returned on all
processes.
INOUT PARAMETERS
root - process to serve as master
timediffs
- array of doubles to be filled in
