CLOG_csync - synchronize clocks for adjusting times in merge
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.
- root
- - process to serve as master
- timediffs
- - array of doubles to be filled in
