clusterpost-lib

It implements the API to submit jobs to clusterpost-server. This library is used by clusterpost-app which implements submit and retrieve functionalities from the server.

New way to submit jobs:

---

var clusterpost = require("clusterpost-lib");

# The config file is is optional, if not provided. It will store the info in your home folder. 
var configfile = './conf.jobCreation.json';


clusterpost.start(configfile)
.then(function(res){

    return clusterpost.parseCLIFromStringAndSubmit("SomeExpensiveTask --img ./data/gravitational-waves-simulation.jpg --img2 ./data/gravitational-waves-simulation.jpg -out ./data.nii.gz")
    .then(function(id){
        console.log(jobid);
    });
});

An example to submit a job (The old way):

---

var clusterpost = require("clusterpost-lib");

var inputfiles = [];

inputfiles.push(path.join(inputdir, "/some/path/img.jpg"));
inputfiles.push(path.join(inputdir, "/some/path/img1.jpg"));
inputfiles.push(path.join(inputdir, "/some/path/img2.jpg"));


var job = {
    "executable": "aVeryExpensiveTask",
    "parameters": [
        {
            "flag": "--img",
            "name": "img.jpg"
        },
        {
            "flag": "--mask",
            "name": "img1.jpg"
        },
        {
        	"flag": "-labelValue",
        	"name": "6"
        },
        {
            "flag": "--labelImg",
            "name": "pvec.nii.gz"
        },
        {
        	"flag": "--outDir",
            "name": "./"	
        }
    ],
    "inputs": [
        {
            "name": "img.jpg"
        },
        {
            "name": "img1.jpg"
        },
        {
            "name": "img2.jpg"
        }
    ],
    "outputs": [
        {
            "type": "tar.gz",
            "name": "./"
        },
        {
            "type": "file",
            "name": "stdout.out"
        },
        {
            "type": "file",
            "name": "stderr.err"
        }
    ],
    "type": "job",
    "userEmail": "[e-mail]"
};

var agentoptions = {
	rejectUnauthorized: false //You can also read a certificate here if you want to use https connection and remove this
}
clusterpost.setAgentOptions(agentoptions);

clusterpost.start()
.then(function(res){
	return clusterpost.getExecutionServers();
})
.then(function(res){
	job.executionserver = res[0].name; //Or select the computing grid where you want to submit your job.
	return clusterpost.createAndSubmitJob(job, inputfiles)
})
.then(function(jobid){
	console.log(jobid);//Job id of the task submitted
})
.catch(console.error)

---

Once your job is submitted, you can retrieve the results with the following script

---

var clusterpost = require("clusterpost-lib");

clusterpost.setClusterPostServer("https://localhost:8180");

var agentoptions = {
	rejectUnauthorized: false
}

clusterpost.setAgentOptions(agentoptions);

clusterpost.userLogin({
	"email": "[e-mail]",
	"password": "passwd"
	})
.then(function(res){
    return clusterpost.getJobs("aVeryExpensiveTask");
})
.then(function(res){
    console.log(res);
})
.catch(console.error)
