25 The ramspeed script takes a number of options which you can use to
26 customise a test. The full run time usage
29 ramspeed -b ID [-g size] [-m size] [-l runs] [-r speed-format]
31 -b runs a specified benchmark (by an ID number):
32 1 -- INTmark [writing] 4 -- FLOATmark [writing]
33 2 -- INTmark [reading] 5 -- FLOATmark [reading]
34 3 -- INTmem 6 -- FLOATmem
35 7 -- MMXmark [writing] 10 -- SSEmark [writing]
36 8 -- MMXmark [reading] 11 -- SSEmark [reading]
37 9 -- MMXmem 12 -- SSEmem
38 13 -- MMXmark (nt) [writing] 16 -- SSEmark (nt) [writing]
39 14 -- MMXmark (nt) [reading] 17 -- SSEmark (nt) [reading]
40 15 -- MMXmem (nt) 18 -- SSEmem (nt)
41 In this scenario, only the first 6 test type will be used for testing.
43 -g specifies a # of Gbytes per pass (default is 8)
44 -m specifies a # of Mbytes per array (default is 32)
45 -l enables the BatchRun mode (for *mem benchmarks only),
46 and specifies a # of runs (suggested is 5)
47 -r displays speeds in real megabytes per second (default: decimal)
49 The -b option is required, others are recommended.
52 type_id - specifies whether to run *mark benchmark or *mem benchmark
53 the type_id can be any number from 1 to 19
57 load - specifies a # of Gbytes per pass
61 block_size - specifies a # of Mbytes per array
66 Parameters for *mem benchmark
67 iteration - specifies a # of runs for each test
