Openlava Server

OpenLava is a 100% free, open source, IBM LSF compliant workload scheduler that supports a variety of high performance computing and analytics applications.

Openlava Server is a set of implementations provided for more convenient operation of Openlava, which implements functions such as local and remote operation modes and parsing of Openlava call results.

Installation

Make sure you have pip (python package manager) installed.

1、python package install

pip install openlava-server

2、source resource install

# download source resource
git clone xxxx.git
# install dependencies
python -m pip install --upgrade setuptools wheel
# packaging
python setup.py sdist bdist_wheel
# install .whl
cd dist && pip install ./openlava_server-1.0.0-py3-none-any.whl

Example

openlava-server enables you to more easily implement openlava's corresponding operations, and parse and process the results.

1、 Local Module

import openlava-server

#import local controller
from openlava-server.factory import LocalController
from openlava-server.lava import JobReceiver, OpenlavaInvoker
from openlava-server.lava.command import BJobCommand

client = LocalController()

openlava_invoker = OpenlavaInvoker()

job_receiver = JobReceiver(client.get_command_dict)

bjob_command = BJobCommand(job_receiver)

lines = openlava_invoker.execute(bjob_command)

2、 Remote Module

import openlava-server

#import remote controller
from openlava-server.factory import RemoteController
from openlava-server.lava import JobReceiver, OpenlavaInvoker
from openlava-server.lava.command import BJobCommand
from session import RemoteSession

session = RemoteSession.SessionBuilder('10.62.4.10','gaotongliang', '1234').build()

client = RemoteController(session)

openlava_invoker = OpenlavaInvoker()

job_reciver = JobReceiver(client.get_command_dict)

bjob_command = BJobCommand(job_reciver)

lines = openlava_invoker.execute(bjob_command)

3、 Batch Execute Module

import openlava-server

from openlava-server.factory import RemoteController
from openlava-server.lava import JobReceiver, OpenlavaInvoker, HostReceiver
from openlava-server.lava.command import BJobCommand, BHostCommand
from session import RemoteSession

session = RemoteSession.SessionBuilder('10.62.4.10','gaotongliang', '1234').build()

client = RemoteController(session)

openlava_invoker = OpenlavaInvoker()

job_reciver = JobReceiver(client.get_command_dict)
host_receiver = HostReceiver(client.get_command_dict)

bjob_command = BJobCommand(job_reciver)
bjob_command = BJobCommand(job_receiver)

openlava_invoker.add_command(bhost_command)
openlava_invoker.add_command(bjob_command)
results = openlava_invoker.batch_execute()

4、 Websocket Setup Methos

from openlavaserver.config import configure
from openlavaserver.handler import WebsocketAdapter

configure("openlavaserver")
ws_client = WebsocketAdapter()
ws_client.set_handler_chain()
ws_client.setup_websocket()
