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
