+ """Execute ramspeed benchmark in a host
+ The ramspeed script takes a number of options which you can use to
+ customise a test. The full run time usage
+ is:
+
+ ramspeed -b ID [-g size] [-m size] [-l runs] [-r speed-format]
+
+ -b runs a specified benchmark (by an ID number):
+ 1 -- INTmark [writing] 4 -- FLOATmark [writing]
+ 2 -- INTmark [reading] 5 -- FLOATmark [reading]
+ 3 -- INTmem 6 -- FLOATmem
+ 7 -- MMXmark [writing] 10 -- SSEmark [writing]

+ 9 -- MMXmem 12 -- SSEmem
+ 13 -- MMXmark (nt) [writing] 16 -- SSEmark (nt) [writing]
+ 14 -- MMXmark (nt) [reading] 17 -- SSEmark (nt) [reading]
+ 15 -- MMXmem (nt) 18 -- SSEmem (nt)
+ In this scenario, only the first 6 test type will be used for testing.
+
+ -g specifies a # of Gbytes per pass (default is 8)
+ -m specifies a # of Mbytes per array (default is 32)
+ -l enables the BatchRun mode (for *mem benchmarks only),
+ and specifies a # of runs (suggested is 5)
+ -r displays speeds in real megabytes per second (default: decimal)
+
+ The -b option is required, others are recommended.
+
+ Parameters
+ type_id - specifies whether to run *mark benchmark or *mem benchmark
+ the type_id can be any number from 1 to 19
+ type: int
+ unit: n/a
+ default: 1
+ load - specifies a # of Gbytes per pass

+ unit: gigabyte
+ default: 8
+ block_size - specifies a # of Mbytes per array
