[Beowulf] Time Measurement

[ThanhVu Nguyen]

Hi, just wondering what the standard way of measure the execution time
?  

2 methods can be : 

1) /usr/bin/time  prog   : this includes all the communcation, i/o ,
loading overhead etc

2) include start_time , end_time code in the program : this won't
include the communication , i/o , loading etc overhead.

what method is usually used ?  thanks  

tvn,
