Installing the Maui Scheduler
This appendix describes how to install and configure the Maui Scheduler to interoperate with
SLURMonanHPXCsystem.
L.1 Overview
The Maui Scheduler is a software tool designed to allow flexible and near-optimal scheduling in
a multiresource, high-performance computing environment. Jobs are screened through a large
number of administrator-configurable fairness policies and then prioritized based on such
factors as job queue time, job expansion factor, and user CPU usage history.
The Maui Scheduler m aximizes control of system resources by allowing certain nodes to be
reserved for specifi c users, groups, accounts, or projects and minimizes the amount of wasted
computer resources by permitting a nticipated downtim e to b e scheduled.
The Maui Scheduler is also a research and analysis tool. The Maui Scheduler collects a large
number of statistics and can analyze this information to determine the effectiveness of the
schedulingapproachbeingusedbyMauiandthe utilization of the resources available.
_________________________ Note: _________________________
The Maui Scheduler can be integrated with SLURM or wit h standard L SF from
Platform Computing. However, Platform Computing does not su ppo rt the use
of the Maui Scheduler with the HP XC implementation of L S F HPC due to its
integration with SLURM on an HP XC system.
L.2 Readiness Criteria
Use the guidelines and requirements in Table L-1 to help you decide whether or not this
procedure is right for you .
Table L-1: M aui Scheduler Readiness C riteria
Requirement Description
System software configuration The Maui Scheduler can be integrated with SLURM on an HP
XC system. However, Maui must not be added to SLURM if
LSF HPC is being used.
Resource management
You cannot use LSF HPC as the resource manager if the Maui
Scheduler is installed to interoperate with SLURM.
Impact on availability The procedures described in this appendix have no negative
impact on system availability.
Experience level HP recommends that you have strong Linux system management
experience. Previous experience installing and configuring the
Maui Scheduler is also helpful
L.3 Before You Begin
Before you ins tall and configure the Maui Sched uler, you must understan d s om e background
information and perform some preliminary tasks.
