UNICORE As We See It Today

A federation software suite

Secure and seamless access to compute and data resources

Focus on scientific applications and workflows

Complies with typical HPC centre policies

Complete solutions: APIs, clients, services, ...

Java/Python based, supports UNIX, MacOS, Windows andmany resource management systems (Torque, Slurm, SGE, ...)

Long development history (since 1997)

Open source, BSD licensed, visit http://www.unicore.eu

Concepts

UNICORE ≡ UNIform Access to COmputing REsources

Site: a resource such as an HPC system including storage

Job: submitted through JSDL including data staging,resource requirements, executable definition and parameters

Hadoop (Yarn) jobs possible, too, in conjunction with HDFS

Resources: features of sites in terms of capacity and capability

Storages: a view into file systems at a certain base directory(mount point). Can be storage external to the site, e. g.Swift, S3, HDFS, CDMI, XtreemFS

Applications: abstractions of applications hiding site-localspecificities, e. g. installation paths or module activations

Workflows: a series of job executions guided by controlstructures, i. e. visual programming

Storage Access

The UNICORE Storage ManagementService (“SMS”) provides a filesystem-likeview of data

Typical functions

mkdir, delete, ls, chmod etc

Start tile transfers

Import/export of data from/to the user’slocal machineSend/receive of data from other serversVarious supported file transfer protocols

File Transfers

Metadata Management ServiceMMS

Automatic extraction

Manual editing of metadata

Searching

2017-03-16 Bjorn Hagemeier Folie 17

Applications

General

Identified by name and version

Site specifics

Pre and post commands for environment setup and tear down

Acquire and return licenses

MPI

Support for application metadata

2017-03-16 Bjorn Hagemeier Folie 18

Generic ApplicationsAutomated generation of GUIs

UNICORE Rich Client and Portal support application metadata

Example

<jsdl:Argument Description="Check input file"

Type="boolean"

Default="..."

ValidValues="true false"

DependsOn="..."

Excludes="..."

IsEnabled="false"

IsMandatory="false">+v$CHECK?</jsdl:Argument>

Possible types: string, boolean, int, double, filename, choice.

Used to be defined by site administrators.

2017-03-16 Bjorn Hagemeier Folie 19

User-Defined Applications

Allow mixing system and userdefined applications

Encourage users to play with anddevelop their own applicationdefinitions

Repository of common applicationdefinitions

Realized by merging system anduser specific IDB contributions

Users cannot change a site’sresources and thus not go beyondadministrator limits

2017-03-16 Bjorn Hagemeier Folie 20

Workflow Features

Simple graphs (DAGs)

Workflow variables

Loops and control constructs

while, for-each, if-else

Conditions

Exit code, file existence, filesize, workflow variables

Clients UNICORE Rich clientCommandline client

Authentication and AuthorizationAAI, for short

In addition to its own,home-grown usermanagement solution, aka.XUUDB, UNICORE supportsSAML-based authentication.

PULL and PUSH-mode arepossible

Typically only need a fewattributes

role (user, server, admin),xlogins, groups

UNITY IdMIdentity Relationship Management

Complete solution for identity, federation andinter-federation managementCan serve as SP and IdP at the same time.

Use SAML 2, OAuth 2, OIDC, LDAP as upstream IdPsServe as IdP for SAML 2 (Web SSO, SOAP, PAOS bindings),SAML 2 Web & SOAP UNICORE Profile, OIDC, OAuth 2
