Introducing HPC Midlands
• BIS/EPSRC e-Infrastructure Centre• Supercomputing for research and industry• On demand access to HPC capacity
– Licensed software from leading vendors, including ANSYS, CD-adapco and MSC Software
• See hpc-midlands.ac.uk/launch-event for case studies from E.ON, Rolls Royce and Tata Steel
Hera cluster:3,000 cores (48 Teraflops)
15TB RAM
120TB Lustre storage
Non-blocking QDR Infiniband
188 compute node blades• 2 x 2.0GHz (8 core) Sandy Bridge • 140 with 64GB RAM (4GB/core)• 48 with 128GB RAM (8GB/core)
Introducing HPC Midlands
Introducing HPC Midlands
Note the 50 node (800 core) and 25 node (400 core) jobs!

Motivations for Moonshot• Desire to avoid separate HPC Midlands
credentials for service users• Use organizational credentials for multiple
services, e.g. OpenSSH, Apache, Samba• Delegated authority for managing user
identities and access to services• Services built around the user not the service
providers (see next slide)• Comfort zones: ssh keys, CLI etc

Motivations for Moonshot
Contents• Introducing HPC
Midlands• Motivations for
Moonshot• Early Moonshot Pilot
Findings• Next Steps
Early Moonshot Pilot Findings• Dedicated HPC Midlands login node
allocated for development work– Live DVD image also available for testing
• Moonshot RPMs from yum.dev.ja.net– Patched versions of FreeRADIUS, OpenSSH,
Shibboleth SP, GSS Server, libraries etc– (Mostly) Install into /opt/moonshot– RPM package dependency fun and games with
vendor respins (common for HPC)
Yum… (github coming soon)
Early Moonshot Pilot Findings
Moonshot up and running in test mode:
hera12# /opt/moonshot/bin/ssh -p 2222 -l "" 127.0.0.1CTRL-EVENT-EAP-STARTED EAP authentication startedCTRL-EVENT-EAP-PROPOSED-METHOD vendor=0 method=21CTRL-EVENT-EAP-METHOD EAP vendor 0 method 21 (TTLS) selectedCTRL-EVENT-EAP-SUCCESS EAP authentication completed successfully[comth@hera12 ~]$
This proves that Moonshot enabled ssh, sshd, gss-server, radiusd and shibd are all talking to each other.

Next Steps
• Get Moonshot installation up and running with institutional RADIUS servers / Trust Router– Loughborough contracted to JANET(UK) to provide
technical support for the Moonshot Pilot– Leicester also working on Moonshot for DiRAC (HPC
for Particle Physics, Astronomy + Cosmology)
• Discussions with industrial collaborators– Firewall holes, VPNs, SOCKS proxies etc– Hosted Moonshot portal to manage access?– JANET connectivity?
