-M mbytes megabytes of ram to test
--reserve-memory If not using hugepages, the amount of memory to reserve for the system
-H mbytes minimum megabytes of hugepages to require
-s seconds number of seconds to run
-m threads number of memory copy threads to run
-i threads number of memory invert threads to run
-C threads number of memory CPU stress threads to run
--findfiles find locations to do disk IO automatically
-d device add a direct write disk thread with block device (or file) 'device'
-f filename add a disk thread with tempfile 'filename'
-l logfile log output to file 'logfile'
--no_timestamps do not prefix timestamps to log messages
--max_errors n exit early after finding 'n' errors
-v level verbosity (0-20), default is 8
--printsec secs How often to print 'seconds remaining'
-W Use more CPU-stressful memory copy
-A run in degraded mode on incompatible systems
-p pagesize size in bytes of memory chunks
--filesize size size of disk IO tempfiles
-n ipaddr add a network thread connecting to system at 'ipaddr'
--listen run a thread to listen for and respond to network threads.
--no_errors run without checking for ECC or other errors
--force_errors inject false errors to test error handling
--force_errors_like_crazy inject a lot of false errors to test error handling
-F don't result check each transaction
--stop_on_errors Stop after finding the first error.
--read-block-size size of block for reading (-d)
--write-block-size size of block for writing (-d). 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.
