nwpc-hpc-model
A key-value model for HPC resources in NWPC. Including models for:
- LoadLeveler's
llq -lquery - Slurm's
sinfoandsqueue -o %allquery - Disk usage and disk space query
Installation
Download source code from Github releases or get the latest code from Github repo.
Run pip install . to install.
Getting started
The following example uses nwpc-hpc-model to extract job id and job owner from a llq -l query.
A config YAML file is used to create query categories.
category_list:
-
id: "llq.id"
display_name: "Id"
label: "Job Step Id"
record_parser_class: "DetailLabelParser"
record_parser_arguments:
- "Job Step Id"
value_saver_class: "StringSaver"
value_saver_arguments: []
-
id: "llq.owner"
display_name: "Owner"
label: "Owner"
record_parser_class: "DetailLabelParser"
record_parser_arguments:
- "Owner"
value_saver_class: "StringSaver"
value_saver_arguments: []
First create QueryCategoryList according to the config json file.
from nwpc_hpc_model.workload.loadleveler import QueryCategoryList, \
QueryCategory, record_parser, value_saver
import yaml
with open('config_file_path', 'r') as f:
config = yaml.load(f)
category_list = QueryCategoryList()
for an_item in config['category_list']:
category = QueryCategory(
category_id=an_item['id'],
display_name=an_item['display_name'],
label=an_item['display_name'],
record_parser_class=getattr(record_parser, an_item['record_parser_class']),
record_parser_arguments=tuple(an_item['record_parser_arguments']),
value_saver_class=getattr(value_saver, an_item['value_saver_class']),
value_saver_arguments=tuple(an_item['value_saver_arguments'])
)
category_list.append(category)Get llq -l command output.
import subprocess
command = "/usr/bin/llq -l"
pipe = subprocess.Popen([command], stdout=subprocess.PIPE, shell=True)
output = pipe.communicate()[0]
output_string = output.decode()
output_lines = output_string.split("\n")Build QueryModel from QueryCategoryList
from nwpc_hpc_model.workload.loadleveler import LoadLevelerQueryModel
model = LoadLevelerQueryModel.build_from_category_list(output_lines, category_list)model contains data of all categories in the config file.
