Grid Engine Management Module

This manual contains information about accessing and using GEMM as well as managing N1GE versions.

Using GEMM

The Grid Engine Management Module (GEMM) for the Sun™ Control Station allows you to install and set up a grid. It also allows you to monitor the performance of the hosts in the grid. This document explains the features and services available through the Grid Engine control module.

GEMM supports the following operating systems and hardware platforms:

  • Solaris 9 and 10 on SPARC, x86, and x64 hardware platforms

  • RedHatLinux 7.3, RedHatLinux 8.0, RedHatLinux 9 on x86 hardware platforms

  • FedoraLinux 1, FedoraLinux 2, FedoraLinux 3 on x86, and x64 hardware platforms

  • RedHatLinux 2.1 WS,RedHatLinux 2.1 AS, RedHatLinux 2.1 ES on x86 hardware platforms

  • RedHatLinux 3WS, RedHatLinux 3 AS, RedHatLinux 3ES on x86, and x64 hardware platforms

  • SuSELinux 9.0 on x86 and x64 hardware platforms

  • JDS 1, JDS 2 on x86 hardware

The GEMM module allows you to:

  • manage different versions of N1 Grid Engine

  • install a master host on the grid

  • install additional compute hosts on the grid

  • monitor and diagnose the performance of the grid

  • uninstall the Grid Engine components from selected compute and access hosts

  • uninstall the Grid Engine components from the master host and all compute and access hosts

  • check the status of Grid Engine (from Station Settings > Active Monitor on the SCS.)

  • configure the monitoring settings for the grid

The following sections describe each of these functions.


Note - In Grid Engine terminology, compute hosts are called execution hosts. Access hosts are called submit hosts.


Installing GEMM

GEMM is part of the Grid Engine Update 4 distribution and is included in the Gemm/tar/n1ge-6_0u4-gemm.tar.gz package. Use the following steps to install GEMM

  1. Unpack the GEMM archive file.

  2. Add GEMM to a Sun Control Station 2.2 system. See the Sun Control Station documentation for instructions on adding a new management module.

Accessing GEMM

You access the GEMM features by clicking on the Monitor menu item on the Sun Control Station main screen as shown in the following figure.

Note - In most of the short procedures in this chapter, the first step is to click the Grid Engine item in the left menu bar and the second step is to click on a sub-menu item. To reduce the number of steps in each procedure, the menu commands are grouped together and shown in Initial Caps. Right-angle brackets separate the individual items. For example, select Grid Engine > Settings means to click Grid Engine in the left menu bar and then click the Settings sub-menu item.


Task Progress Dialog

When you launch a task (for example, when installing a master host or uninstalling a host), a Task Progress dialog appears in the user interface (UI). This dialog has a Status field indicating the current status of the task and a progress bar. When the progress bar displays 100%, the task has completed.

Figure 1-2 Task Progress Dialog

If you want to perform another task in the UI while the current task is underway, you can put the Task Progress dialog in the background. Simply click the Run Task In Background button located below the progress bar.

To return to the Task Progress dialog, select Administration > Tasks on the left. The Task table appears. If the task is still underway, a status message displays in the Duration column. Click on the progress-bar icon in this column to re-display the Task Progress dialog for this task.

Once the task is complete and the progress bar displays 100%, two buttons appear below the Task Progress dialog: Done and View Events.

  • To view the list of events associated with the completed task, click View Events. The Events For <Task> table appears. If you then click the up-arrow icon in the top-right corner, the Tasks table appears.

  • To return to the previous screen, click Done.

Managing Versions

GEMM allows you to upload one or more versions of N1 Grid Engine, and choose which one to deploy on the grid. To do these tasks, click the Versions menu item to display the Version Management page.

Figure 1-3 Version List Page

This page is where you can upload, modify and manage different versions of N1 Grid Engine software.


Note - You can only deploy one version at any given time. If you wish to deploy another version, you must first uninstall the grid from all the hosts.
