clog_csync(4) - Linux man page

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
