NAME
CLOG_csync - 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
