Introduction

Part 1: User-level practice (App Portal)

Part 2: Admin-level practice (Mgmt Portal)

Introduction Originally, we intended to use our 3-node

testing environment to support the exercise, but it’s occupied now for robustness testing.

So here we will use the newly installed one-node environment kindly provided by HKU to do the CNGrid GOS 3.0 demonstration. – Portal server: 147.8.178.206– Backend Server: 147.8.178.207

This exercise is to show the basic functions on CNGrid GOS 3.0 . For more information, pls come to our website : – http://vega.ict.ac.cn/gos – See “Material” Section on the left side

Part 1: User-Level Operation

Step1.1: Login onto GOS3.0 portal Step1.2: Submit a grid job Step1.3: Get global job records Step1.4: Query job details Step1.5: Get job output Step1.6: Manipulate files in job directory Step1.7: Manage job Step1.8: Accounting facilities Step1.9: File facilities

5

Step1.1: Login onto GOS3.0 portal

Get your Login Username and Passwords:– We have prepared one username for each column:– E.g: Users in column 1:

• UserName is : demo001@cngrid.org• Password is: demo001

Each Login Account has been mapped onto one local linux account on this testing node.– e.g:

• demo001@cngrid.org is mapped to demoHKU001 • The password for this local username is: ictgos3

6

Step1.1: Login onto GOS3.0 portal Please open your Internet Browser

– Both IE and Firefox is okay , Firefox is strongly recommended– “Start” “All Programs” “Mozilla Firefox”

Type in the URL of the GOS Application Portal• http://gos1.cs.hku.hk:8080/hpcgapp

Type in your Grid account and password:

Step1.2: Submit a grid job

The administrator has added two types of software into this testing grid node:– Blast : Basic Local Alignment Search Tool

• DNA & Protein sequence searching– General: the simplest application for testing

• You may specify any Job logic in this software type• Not safe for grid node, Just for testing purpose

Here I’d like to use the Blast software

8

Step1.2: Submit a grid job

9

Step1.2: Submit a grid job

10

Step1.3: Query Global Job Records Query all the jobs submitted by yourself

– No matter they are on which grid node

11

Step1.4: Query job details– Right-click a job record and press “View”– Input passwd for the mapped linux account

12

Step1.5: Get job output

Get the standard out stream of indicated job (even when it’s not finished yet)

13

Step1.7: Manage Job To terminate the indicated job To re-run the indicated job

– Generated job will share the same home dir with the original job, with data shared between these 2 job.

14

Step1.8: Accounting facilities– Click the “AccountInfo” button on the left

• StatisticInfo: the job statistics of this node for this Grid user• Accounting details: List the local job accounting information

15

Step1.9: File facilities Access your files on the cluster via portal

16

Part 2: Admin-level functions via portal

The admin-level functions could only be operated by the Administrator of Grid-Node.

So I will show the whole processing of using Admin-level functions via portal.

17

Step2.1: Manage Cluster Info. Add/Manage Cluster information

– The jobs are finally be passed to local cluster Add/Manage Queue on this cluster

– The jobs will be waiting in some queue of this cluster– Different queues may have different restrictions on them.

18

Step2.2: Manage Software Info. Add/Manage SoftwareType:

– A SoftwareType is identical within a grid– Same type of applications provided by different Grid nodes could

be grouped into one SoftwareType– Define the common logic of the same type of jobs.

Add/Manage Software instance for this Grid Node.

19

Step2.3: Manage User Mapping UserMapping: Grid User Linux Account

– Grid User : identical in multiple Grid Nodes.– Linux account : on local Cluster system.
