CLOG_csync(4)
synchronize clocks for adjusting times in merge
SYNOPSIS
void CLOG_csync( root, diffs )
int root;
double diffs[];
This version is sequential and non-scalable. The root process serially
synchronizes with each slave, using the first algorithm in Gropp, "Scalable
clock synchronization on distributed 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
