If not defined, the size of block for writing will be defined as the size of block for reading --segment-size size of segments to split disk into (-d) --cache-size size of disk cache (-d) --blocks-per-segment number of blocks to read/write per segment per iteration (-d) --read-threshold maximum time (in us) a block read should take (-d) --write-threshold maximum time (in us) a block write should take (-d) --random-threads number of random threads for each disk write thread (-d) --destructive write/wipe disk partition (-d) --monitor_mode only do ECC error polling, no stress load. --cc_test do the cache coherency testing --cc_inc_count number of times to increment the cacheline's member --cc_line_count number of cache line sized datastructures to allocate for the cache coherency threads to operate --cc_line_size override the auto-detected cache line size --cpu_freq_test enable the cpu frequency test (requires the --cpu_freq_threshold argument to be set) --cpu_freq_threshold fail the cpu frequency test if the frequency goes below this value (specified in MHz) --cpu_freq_round round the computed frequency to this value, if set to zero, only round to the nearest MHz --paddr_base allocate memory starting from this address --pause_delay delay (in seconds) between power spikes --pause_duration duration (in seconds) of each pause --local_numa choose memory regions associated with each CPU to be tested by that CPU --remote_numa choose memory regions not associated with each CPU to be tested by that CPU --channel_hash mask of address bits XORed to determine channel. Mask 0x40 interleaves cachelines between channels --channel_width bits width in bits of each memory channel --memory_channel u1,u2 defines a comma-separated list of names for dram packages in a memory channel. Use multiple times to define multiple channels.
