gc_spyu is being rewritten for yapapi 0.9. it is not usable at the latest tag v0.1.3. thank you for your patience.

gc_spyu

espy cpu model information from specific providers and persistently store for later retrieval.

The current Golem network conceals the model information of providers. While obtaining model specifications is possible utilizing the yapapi repository examples (Golem code), it only randomly selects providers. gc_spyu solves this problem of only random specifications by facilitating the procurement of specific provider's (cpu) model information.

For information on the global supercomputer that is Golem and how to run or engineer apps on it, visit https://www.golem.network

For a listing of providers to inspect, visit https://stats.golem.network or invoke my gc__listoffers (https://github.com/krunch3r76/gc__listoffers)

first installation

$ git clone https://github.com/krunch3r76/gc_spyu.git
$ cd gc_spyu
(gc_spyu)$ git checkout v0.1.3
(gc_spyu)$ python3 -m venv myvenv # python3.9 or python3.8
(gc_spyu)$ . myvenv/bin/activate
(myvenv)$ pip install -r requirements.txt

check for new / latest release tag

(gc_spyu)$ git fetch
From github.com:krunch3r76/gc_spyu
   d87b579..01f72be  master     -> origin/master
 * [new tag]         v0.1.3     -> v0.1.3

upgrade installation to latest tag, removing current installation

(gc_spyu)$ git checkout master
(gc_spyu)$ git checkout --hard HEAD
(gc_spyu)$ git pull
(gc_spyu)$ git clean -dfx
(gc_spyu)$ git checkout v0.1.3

DEMO

spyu_v0.1.2.mp4

USAGE

invocation

(myvenv)$ ./gc_spyu.py --spy <space delimited list of nodes>

to inspect etam and q53 on testnet, subnet devnet-beta

(myvenv)$ ./gc_spyu.py --spy etam q53

to inspect collossus, odra, and whirlwind on testnet, subnet public-beta

(myvenv)$ ./gc_spyu.py --disable-logging --subnet-tag public-beta --spy collossus odra whirlwind

to use the gc__filterms / gc__listoffers environment setting

(myvenv)$ GNPROVIDER=['0x3dd491','0xcef890','etam'] ./gc_spyu

TROUBLESHOOTING

If the script fails to run and you see errors including:

ValueError: loop argument must agree with lock
AttributeError: 'SmartQueue' object has no attribute '_new_items'

please use a version of Python < 3.10.

python3.9 -m venv myvenv
# etc

utils.py from yapapi examples was utilized to start the Golem process and help manage exceptions. To see the original code, browse: https://github.com/golemfactory/yapapi/blob/master/examples/utils.py

data_directory.py module to get a cross-platform specific data directory was adapted from code shared by an Honest Abe on a discussion at: https://www.py4u.net/discuss/161917

MORE

Stay tuned for gc_listoffers interop (some interop already implied by filterms).
