       0	  92.1	 127.1	
       1	 129.4	  90.0	

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        :	122130.1	
3:1 Reads-Writes :	112893.9	
2:1 Reads-Writes :	110465.2	
1:1 Reads-Writes :	99124.2	
Stream-triad like:	109274.7	

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
