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
