Mining parameters?

I'm wondering what all the parameters mean.

For example:
--farm-recheck 300 //what does the number indicate?
-G //GPU minning I guess?
-F
and
--cl-global-work 16384

Thanks!

    theres no manuals or wiki with all the parameters listed?

    -G switches from CPU to GPU mining
    --cl-global-work fine tune your cards. Value of 16384 is good for most cards.

    I'm with u DRG, here are some I'd like to know also

    setx GPU_MAX_ALLOC_PERCENT 100
    setx GPU_USE_SYNC_OBJECTS 1
    setx GPU_MAX_HEAP_SIZE 100
    --cl-local-work 128

    setx commands tell AMD drivers preset variables. Always good to be set all of that options, some mining programs require these settings to work properly

    @DRG

    --farm-recheck is the frequency in milliseconds that ethminer will poll geth (or eth-proxy) for new work
    -G Yes, switches on GPU mining
    -F farm mode, point it to node
    --cl-global-work 16384 and
    --cl-local-work 128 are tune the chunk of work that the GPU's must hash through. It's not necessary.

    e.g. ethminer -G -F http://192.168.1.1:8545/ --farm-recheck 200

    With a small farm recheck setting you will see apparent instability in your hashing output. If you want to better guage how fast your hashing, you can set it to 2000 just as a diagnostic, but set it low again for actual mining else you might submit work on stale blocks.

    With 256 will get more mhs ? Or is better 128?

    @anonymous95 you should try it by yourself, not all card have same config, but i use 128
