"""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]
8 -- MMXmark [reading] 11 -- SSEmark [reading]
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
type: int
unit: gigabyte
default: 8
block_size - specifies a # of Mbytes per array
type: int
unit: megabyte
default: 32
Parameters for *mem benchmark
iteration - specifies a # of runs for each test
type: int
unit: n/a
default: 1
