•  Individual application licenses can cost >$500,000 per seat •  Single most important asset being managed •  Way more important than 50-100x cheaper server •  Do everything required to keep those licenses busy •  And make those applications perform at top speed

•  Even if cost per seat is similar to other assets there are still very specific challenges: •  Know what you have and who uses it. Then optimize. •  Pay for as few as possible but for as many as necessary •  Accelerate project schedules by providing preferential access to licenses to

users/departments/projects needing it the most •  Adjust dynamically to changing demands

•  Allocate licenses based on funding/entitlements •  Share unused licenses; share across geos •  Account and do charge-back for license consumption •  Reserve licenses for mission critical project phases

•  Improving license utilization provides instant ROI and can result in dramatic savings! Often much more than through any other means of optimizing a capacity computing environment!

• New product released in July 2013 •  Must be using Univa Grid Engine 8.1.5 or later

• Open architecture for support of arbitrary License Management facilities •  Initial support for FlexLM only

• Replaces and vastly exceeds previously existing means for managing licenses with Univa Grid Engine •  e.g. via consumables or qlicserver (aka the Olesen

method)

Multiple License Managers

•  Aggregate licenses across multiple license managers •  Inside a cluster and across clusters, organizationally

or geographically dispersed •  Minimizes idle time of licenses •  Allows to implement cross-company license usage

policies

Saves cost through optimized utilization of licenses

Fair Sharing of Licenses

• Distribute licenses to users, user groups and projects based on Fair Share policy •  Allows for temporary over-usage with compensation later •  Allows for assignment of shares per license per user •  Option for �default� user that matches requests from

unlisted users • Again across clusters and license managers

Faster ROI through aligning license usage with business demands

Fair Sharing of Licenses (cont.)

•  Example: 6 Users, 3 Licenses, with default users –  Users: alan, bob, cathy, dan, edward, fritz –  License: license-a, license-b, license-c –  Default users for each license



8

Project-Based Sharing of Licenses

• Distribute licenses within projects (as well as departments and users) based on fixed shares •  Always the same entitlement

for license access •  No overage or underage

• Also across clusters and license managers


Shares Projects 70 %

HI 70 % MED 20 % LO 10 %

Departments 20 % Development 10 % Test 10 % Production 80 %

Users 10 % Maria 25 % Steve 15 % John 50 % Susan 10 %


9

Limiting License Requests

• Limit license consumption – Quotas per license for users and user groups –  Each quota can have multiple Rule Sets –  Rule Sets are evaluated in order. First match

wins.


$ loconf -srqs license-a-quota { name license-a-quota description All of the quota rules for license-a enabled TRUE limit users {cathy,bob} to license-a=10 limit users @power_users to license-a=100 limit to license-a=20 }


Preferential Access to Licenses

10 Copyright*©*2013*Univa*Corpora4on,*All*Rights*Reserved.*

•  Implements share what you can spare •  Licenses are owned by an organization and will be

utilized by it first •  But unutilized licenses can be shared

Pre-emption of licenses

•  Ensure access to required licenses for the most important workloads

•  Withdraw (pre-empt) license from low priority job and hand to high priority job


License Usage over Time

High Prio Job Low Prio Job


12

Reserving Licenses

•  Provide license access at a designated time in the future •  Ensure license requirements can be met together with other

dependencies of the job •  Backfilling utilizes license prior to the start of the reservation

for other, short-running jobs

Grid Engine / Non-Grid Engine Use

•  Allows for license management functionality also without Grid Engine being utilized

•  Or for situations with parts of the resources controlled by Grid Engine and parts of them being unmanaged

Save cost by optimized use of licenses

Conclusions

•  License Management is at least as important as managing other valuable assets in a cluster

•  SW licenses are often the most important and most rewarding asset to be managed

•  Univa License Orchestrator is a novel product which in combination with Univa Grid Engine addresses the challenges of license management
