nodejs-winhpcjs

Nodejs command wrapper for Windows HPC Cluster Manager

Introduction

Submit job to a Windows HPC server from a nodejs application and retrieve files from a working directory.

For now only basic function are implemented: job list, job submit, job cancel(jobId), nodes list and only support local installation.

Basic usage

Edit ./config/winhpcserver.json" with your information

var win_config = {
        "method"                : "local",
        "username"              : "user",
        "domain"                : "DOMAIN",
        "headnode"              : "winserver",
        "localCopy"             : "COPY",
        "binariesDir"           : "C:\\Program Files\\Microsoft HPC Pack 2008 R2\\Bin",
        "useSharedDir"          : true,
        "workingDir"            : "c:\\Scratch",
        "sharedDir"             : "HEADNODE\\\\Scratch"
};

var winhpcjs = require("./winhpcjs.js")

Generate a submission script with the parameters in jobArgs and save it inside localJobDir

winhpcjs.winscript_js(jobArgs, localJobDir, callback(err,data))

Submit a job with the following submissionScript and send the jobFiles along

winhpcjs.winsub_js(win_config, [submissionScript, jobFiles, ..], callback(err,data))

Gather server information

winhpcjs.winmgr_js(win_config, callback);

Gather node info

winhpcjs.winnodes_js(win_config, nodeName, callback(err,data));

Gather job list

winhpcjs.winjobs_js(win_config, callback(err,data));

Gather job information

winhpcjs.winjobs_js(win_config, jobId, callback(err,data));

List files in working directory

winhpcjs.windir_js(win_config, jobId, callback(err,data));

Download files from a working directory to the localJobDir

winhpcjs.winretrieve_js(win_config, jobId, [jobFiles,..] , localJobDir, callback(err,data))

Cancel a job

winhpcjs.windel_js(win_config, jobId, callback(err,data))
