a generic scheduler.

Choosing Between a Scheduler and Job Manager

You shoul d cons

ider the following when deciding to use a scheduler or the

MathWorks job m

anager for distributing your tasks:

• Does your clust

er already have a scheduler?

If you already h

ave a scheduler, you may be required to use it as a m eans

of controlling

access to the cluster. Your existing scheduler might be just

as easy to use a

s a job manager, so there might be n o need for the extra

administrati

on involved.

• Is the handlin

g of distributed computing jobs the only cluster scheduling

management yo

uneed?

The MathWorks

job manager is designed specifically for MathWorks

distributed

computing applications. If other scheduling tasks are not

needed, a thi

rd-party scheduler might not offer any advantages.

• Is there a fil

e sharing configuration on your cluster already?

The MathWork

s job manager can handle all file and data sharing necessary

foryourdist

ributed computing applications. This might be helpful in

configurati

ons where shared access is limited.

• Are you inter

ested in batch or interactive processing?

When you use a

job manager, worker processes usually remain running at

all times, de

dicated to their job manager. With a third-party scheduler,

workers are

run as applications that are started for the evaluation of tasks,

and stopped

when their tasks are complete. If tasks are small or take little

time, star

ting a worker for each one might involve too much ove rhead time.

• Are there se

curity concerns?

Your schedu

ler may be configured to accommodate your particular security

requireme

nts.

• How many no

des are on your cluster?
