Measuring Peak Memory Bandwidths for the system
Bandwidths are in MB/sec (1 MB/sec = 1,000,000 Bytes/sec)
Using all the threads from each core if Hyper-threading is enabled
Using traffic with the following read-write ratios
ALL Reads        :	144906.6	
3:1 Reads-Writes :	130347.1	
2:1 Reads-Writes :	126626.7	
1:1 Reads-Writes :	114846.3	
Stream-triad like:	125606.5	

Measuring Memory Bandwidths between nodes within system 
Bandwidths are in MB/sec (1 MB/sec = 1,000,000 Bytes/sec)
Using all the threads from each core if Hyper-threading is enabled
