MB/AP Bench Test Instruction

(1/2) > >>

Dirk:
Because of my Message in the SETI-Beta Forum which I wrote for 15 days...

I made something wrong because of the .wisdom file creation?

It's possible to make a MB/AP Bench Test Instruction?

Thanks.

Raistmer:
Did you read existing instruction before asking?

Dirk:
I'm a semi advanced user.
I know a bit how to make bench test runs.

AstroPulse worked well, MultiBeam not (slightly deeper explanation).

Of course, I read the readme.txt files.
But, there I can't read this which I asked in the above linked message.

E.g. (after my experiences)...

AP bench test runs (on NV GT730):

APbench211_minimal.7z (which have the WU #ap_genwis.dat incl. This kind of file isn't in the MultiBeam tool, because of this always two times superfluous runs)
ap_Zblank_2LC67.wu of ap_Zblank_2LC67and6LC67.7z

In short (something like this, for an entry level, low end VGA card)...
cmdline tests:
-unroll 2 up to 10 (+1)
-ffa_block 256 -ffa_block_fetch 128 up to -ffa_block 2048 -ffa_block_fetch 1024 (+128, rough) (+/-64, fine)
-tune 1 8 4 1 up to -tune 1 64 4 1 (1st N *2)
-tune 2 8 1 1 up to -tune 2 256 1 1 (1st N *2)
-oclFFT_plan 16 8 32 up to -oclFFT_plan 256 32 256 (all possible N's specially written)
-sbs 32 up to -sbs 512 (N *2)
-skip_ffa_precompute (without N's)


Like this above for AP, I would like to have this also for MB.
Until now I have no ideas which N's are possible and if the cmdline settings are alone (e.g. -unroll N) or connected together (e.g. -ffa_block N and -ffa_block_fetch N).

The currently available bench test MB WUs are too small/fast for very fast VGA cards.

For MB is possible (I have no idea which N's are possible and if the cmdline settings are alone or connected together):

-period_iterations_num N
-spike_fft_thresh N
-sbs N
-use_sleep_ex N
-no_caching
-tune N Mx My Mz
-oclfft_tune_gr N
-oclfft_tune_lr N
-oclfft_tune_wg N
-oclfft_tune_ls N
-oclfft_tune_bn N
-oclfft_tune_cw N


Of course -use_sleep is needed for AP and MB NV OpenCL apps.

Also the download possibilities of all available apps (stock are newer than Installer ones).

It's a pity, sad and annoying that I can't let run SETI@home like other projects (Plug&Play or "just out of the box and fine") for to get max. performance.


Until I finshed this AP and MB bench test runs (for to find the best/fastest cmdline settings) I don't let run SETI@home in my BOINCs.


Thanks.

Mike:
I`m not sure what you are talking about.

The NV read me`s have examples of best params to use, same as AMD.

Most users are quite happy with them.

Maybe you can get a few seconds more out of it but thats host dependent.

What hell make you think you can do that for other projects ??? Or do you think that if there is no options then max possible performance already achieved?
What a perverted way of thinking started to spread recently... Ok, forget about options. Just run stock. It's the best you can do. Just as with other projects.
