gc__filterms

a package that facilitates whitelisting or blacklisting on Golem from the command line

compatible with yapapi 0.10.0 along with Marble Castle. now with cpu features filtering. network filtering coming soon.

gc__filterms solves the problem of seeing tasks go to providers that are not performing or behaving well. it is a tool to empower the requestor to avoid (or select) providers of interest. specifically, it augments any current strategy the requestor script has designed by checking offers against criteria to filter for or against, currently filtering only on provider names and node addresses (partial ok) or cpu features.

usage

first clone the repo directory into your script directory

$ git clone https://github.com/krunch3r76/gc__filterms

set up your python script

add the following import statement to the py script that instantiates the Golem object

from gc__filterms import FilterProviderMS

when instantiating the Golem object, assign a FilterProviderMS object (in-place ok) to the the named parameter strategy:

async with Golem(
	budget=10.0,
        subnet_tag=subnet_tag,
        payment_driver=payment_driver,
        payment_network=payment_network,
        strategy=FilterProviderMS()
    ) as golem:
        #...

quickstart overview

set the environment variables to whitelist and/or blacklist providers and run the script, as in:

requestor$ GNPROVIDER=bristlecone python3 script.py
requestor$ GNPROVIDER=[azathoth-rnd,mf] python3 script.py
requestor$ GNPROVIDER_BL=[rustedrobbie,psychocalvin,sycamore] python3 script.py
requestor$ FILTERMSVERBOSE=1 GNFEATURES=[processor_trace] GNPROVIDER=[etam,ubuntu-2rec,witek,golem2005,mf] GNPROVIDER_BL=[sycamore] ./script.py
# or export first, notice addresses are permitted
requestor$ export GNPROVIDER_BL=[0x4316e,0x65df,0xb6abad,sycamore]
requestor$ python3 script.py
#etc

in powershell

> $env:GNPROVIDER="[etam]"
> python3 script.py

or create a new text file script.ps1 with the following content:

$env:FILTERMSVERBOSE=1
$env:GNFEATURES="[processor_trace]"
$env:GNPROVIDER="[etam,ubuntu-2rec,witek,golem2005,mf]"
$env:GNPROVIDER_BL="[sycamore]"
python script.py

> .\script.ps1

note: when filtering by address, filtering is against the node address, not the wallet address

advanced examples

multiple providers

requestor$ GNPROVIDER=[qbam,etam] ./ssh.py NOTE: note that i did not quote the assignment of the bash variable (and there are no spaces!). this is the most direct way of listing.

blacklisting

set the GNPROVIDER_BL environment variable, for example requestor$ GNPROVIDER_BL=[qbam,etam] ./ssh.py

a specific example for testing

you might then run golemsp on testnet (in a separate machine/vm) with:

provider$ golemsp run --payment-network=testnet --subnet=devnet-beta

let this provider node be named "jupiter-legacy".

then, on the requestor side (assuming Golem constructed with payment_network='testnet', subnet_tag='devnet-beta'), e.g. using the blender example, you can run:

requestor$ GNPROVIDER=jupiter-legacy python3 ./blender.py

and see tasks (in the log) go only to jupiter-legacy (on devnet-beta)!

wrap an existing strategy

import yapapi
from decimal import Decimal
mystrategy=yapapi.strategy.LeastExpensiveLinearPayuMS(
    max_fixed_price=Decimal("0.00")
    , max_price_for=
    {
	yapapi.props.com.Counter.CPU: Decimal("0.01")
	, yapapi.props.com.Counter.TIME: Decimal("0.0011")
	}
    ) 

async with Golem(
	budget=10.0,
        subnet_tag=subnet_tag,
        payment_driver=payment_driver,
        payment_network=payment_network,
        strategy=FilterProviderMS(mystrategy)
    ) as golem:
        #...

wrap a wrapped strategy

import yapapi
from decimal import Decimal
    my_modified_strategy = yapapi.strategy.DecreaseScoreForUnconfirmedAgreement(
            base_strategy=mystrategy
            , factor=0.01
    )

    async with Golem(
        budget=1.0,
        subnet_tag=subnet_tag,
        payment_driver=payment_driver,

usage tips

conditional import

try:
    moduleFilterProviderMS=False
    from gc__filterms import FilterProviderMS
except ModuleNotFoundError:
    pass
else:
    moduleFilterProviderMS=True
    
#...

 if moduleFilterProviderMS:
                strategy=FilterProviderMS(self.strat)
            else:
                strategy=self.strat

create a symlink to the directory with the filterms repo

(in directory of project)$ ln -s <path to gc__filterms repo dir> gc__filterms

comments

if you do not set the GNPROVIDER environment variable, the script passes the default LeastExpensiveLinearPayuMS with sane defaults.

conclusion

this is a fourth rendition of a package/suite that aims to provide more convenience and flexbility to requestors on top of yapapi for testing (current state) or enhancing (planned features). stay tuned for further developments inlcuding more integration with gc__listoffers.
