+A perl wrapper script (bench.pl) is also provided to scan certain range of thread counts and determine the absolute highest sustained main memory bandwidth. In order to use it `likwid-pin` has to be in your path. The script has three required and one optional command line arguments:
+```
+$./bench.pl <executable> <thread count range>  <repititions> [<SMT setting>] 
+```
+Example usage:
+```
+$./bench.pl ./bwbench-GCC 2-8 6
+```
+The script will always use physical cores only, where two SMT threads is the default. For different SMT thread counts use the 4th command line argument. Example for a processor without SMT:
+```
+$./bench.pl ./bwbench-GCC 14-24  10  1
+```
