schrodinger.job.host_check module

This module provides functions to support hosts-file and remote-command configuration in the Configuration GUI.

class schrodinger.job.host_check.Error(message, level=None, description='', advice='', output='')

Bases: object

An Error represents an system-level issue that prevents remote commands executed via ssh from succeeding.

__init__(message, level=None, description='', advice='', output='')

schrodinger.job.host_check.ssh_check(host, user='')

Check whether remote commands to the given host succeed or not. An alternate remote account name can be specified.

Results are returned in a list of Error objects reporting any serious problems uncovered with remote commands to the specified host.

The current implementation involves executing a separate test program to diagnose remote-command issues, remote_command.pl.

schrodinger.job.host_check.host_check(entry, hostfile='', cwd=None)

Check whether jobs can be run successfully using the given host entry. A non-default hosts file can be specified; otherwise the usual hosts file is used.

Results are returned in a list of Error objects reporting any serious problems uncovered with jobs launched to the specified host entry.

The current implementation involves executing a separate test program, “$SCHRODINGER/installation_check”, to manage the test job and diagnose the problem, if it fails.

Parameters

cwd (str) – Use to set the current working directory.
