2 Grid technology

Grid technology

Flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resource Grid architecture Defined using services and protocols Using the sand hourglass model similar to the TCP/IP protocol stack From The Anatomy of the Grid: Enabling Scalable Virtual Organizations

3 Grid architecture

Grid architecture

Fabric resource specific operations Connectivity main communication and authentication proto. Resource usage, monitoring, control of single resource Collective global interactions between collections of resources

4 Globus Toolkit

Globus Toolkit

No official Grid standards exist but Globus Toolkit has emerged as the de facto standard for several important Connectivity, Resource, and Collective protocols

5 Fabric

Fabric

13 Globus Toolkit installation

Globus Toolkit installation

After deploying the selected packages and running gpt-postinstall we execute setup-gsi configures grid serurity In order to use the installation we need to acquire certificates user certificate grid-cert-request creates usercert-request.pem host certificate grid-cert-request host <hostname> creates host.req LDAP certificate grid-cert-request cn ldap/hostname creates server.req

14 Globus Toolkit installation

Globus Toolkit installation

Globus services installation In /etc/services insert Gsigatekeeper 2119/tcp #Globus Gatekeeper gsiftp 2811/tcp #GridFTP xinetd/globus-gatekeeper service gsigatekeeper { socket_type = stream protocol = tcp wait = no user = root server = GLOBUS_LOCATION/sbin/globus-gatekeeper server_args = -conf GLOBUS_LOCATION/etc/globus-gatekeeper.conf disable = no } Similar for grid-ftp

15 Globus Toolkit verification

Globus Toolkit verification

To test the functionality of the gatekeeper execute grid-proxy-init -debug -verify globus-personal-gatekeeper start Starts personal proxy and returns our contact string hostname:4589:/O=Grid/O=Globus/CN=Your Name To execute a command we use globus-job-run <contact> /bin/date

16 Globus Toolkit verification
