I used the low-tech method:

1. open 2nd term;
2. create 2nd rundir under gpuowl-dir, cd into same;
3. populate worktodo by running primenet.py (which I see is based on the same-name py-script of another GIMPS coder who shall remain nameless, but who restored the same "run just once and quit rather than recurring by adding '-t 0'" option which exists in his original script to the gpuowl one :);
4. ../gpuowl

I use same system sclk and fan settings for 2-worker-running as for 1.

Do you know about -pool option? You create a single folder where you put the output of primenet.py , and run multiple instances, each in its own folder (indicated with -dir) all feeding from the common pool (indicated with -pool). You can also put config files in the pool dir, for shared config. Next logical step is to put the -pool option in the config file of each individual instance, and now you can start it with only -dir.

I'm afraid all that is not very clear, so let's see an example config:

~/gpuowl-xfx/config.txt contains:
-cpu XFX -uid 780c28cffffffeee -pool /home/user/pool

(note that the gpu is indicated not by -d <position> but by UID, which is very useful when shuffling GPUs around. A symbolic name "XFX" is associated to it).

~/pool/config.txt contains:
-user name

(because the user is shared by all instances)

primenet.py only knows about the pool dir:
~/gpuowl/tools/primenet.py -u <user> -p <password> --dirs ~/pool --tasks 4 -w PRP &

There are warnings there telling you that you are passing -use options that don't exist (because they have been removed), some have been replaced by more general e.g. there is still a T2_SHUFFLE that you may want to try. But a bigger benefit would be to move to ROCm (either 2.10 or 3.1).

Thanks, Mihai, but after a few more lines your recipe was already more complex than my neoluddite recipe. :) Perhaps I'll find it useful when I build my multi-GPU dream system later this year.

To paraphrase the late great SNL comedian Phil Hartman by way of his recurring [i]Unfrozen Caveman Lawyer[/i] sketches: "I'm just a *caveman* - the ways of you modern human are strange and unfathomable to me. (But what I do know is that my client deserves at least a $5 million triple-damages settement for injuries and psychological trauma resulting from the defendant's spilling ketchup on him.)"

Thanks - I long ago did the featuremask fiddle. My issue is not a missing pp_od_clk_voltage entry, is that Ubuntu is not allowing me to modify it. Not a huge deal, just eating the extra Watts and running with mclk at stock. Could become an issue when I build that multi-GPU dream system later this year, though - have an 850W[sup]*[/sup] PS laid in, intended to drive something along the lines of an 8-core AMD CPU plus 3 Radeon VIIs. That will likely need sclk = 3 undervolting of the latter to get the wattage within what the PS can stably handle, would be nice to be able to tune mclk to help maximize throughput of the setup by way of another "tuning dial".

-------------

[sup]*[/sup]That seemed to be the sweet spot in terms of $/watt at $120, all the >= 1KW PSs I looked at cost well over $200. Plus I don't want to be running a system needing more than a kW, our household circuit breakers start tripping at that level when anything else that is power-hungry (e.g. toaster, hair dryer) running off the same part of the "household grid" gets turned on.

Documentation of what -use options are available would be helpful.[/QUOTE]

There is some brief documentation at the top of gpuowl.cl, that we try to maintain in sync with the code as it changes:

[QUOTE=Prime95;539912]Using not yet committed code:

Rocm 2.10, sclk 4, mem 1200, FFT 5M; 662us/it.
Running 2 instances: 604us/it (200W measured by rocm-smi)

I love this GPU.[/QUOTE]

Way to go Mihai!! With his latest commit this GPU has broken through the 600us barrier -- 597us.
