a comma separated list of values in form of\n\
AxB where A is the number of threads to run in\n\
each thread block and B is the number of thread\n\
blocks to launch. If less values than devices in use\n\
are provided, the last value will be used for\n\
the remaining devices. If you don't need to vary the\n\
value between devices, you can just enter a single value\n\
and it will be used for all devices. (default: 8x40)\n\
--bfactor=X Enables running the Cryptonight kernel in smaller pieces.\n\
The kernel will be run in 2^X parts according to bfactor,\n\
with a small pause between parts, specified by --bsleep.\n\
This is a per-device setting like the launch config.\n\
(default: 0 (no splitting) on Linux, 6 (64 parts) on Windows)\n\
--bsleep=X Insert a delay of X microseconds between kernel launches.\n\
Use in combination with --bfactor to mitigate the lag\n\
when running on your primary GPU.\n\
This is a per-device setting like the launch config.\n\

--cert=FILE certificate for mining server using SSL\n\
-x, --proxy=[PROTOCOL://]HOST[:PORT] connect through a proxy\n\
-k, --keepalive send keepalive requests to avoid a stratum timeout\n\
-t, --threads=N number of miner threads (default: number of nVidia GPUs)\n\
-r, --retries=N number of times to retry if a network call fails\n\
(default: retry indefinitely)\n\
-R, --retry-pause=N time to pause between retries, in seconds (default: 30)\n\
--timeout=N network timeout, in seconds (default: 270)\n\
-s, --scantime=N upper bound on time spent scanning current work when\n\
long polling is unavailable, in seconds (default: 5)\n\
-q, --quiet disable per-thread hashmeter output\n\
