HPC in UCD
Research IT Service 2005
HPC is Core Service Phaeton Cluster -
Community & Shared Services
11% ICHEC Stokes Cluster 2008

What's the problem?
Physical HPC Cluster is inelastic Users sometimes need more resources than are
available Adding resources can be a slow process Capital intensive process

Possible Solutions
"Pre-order" hardware Buy compute time on other
facilities Investigate "The Cloud"

Which Cloud?
Cloud options Locations Different definitions
"a style of computing where massively scalable IT enabled capabilities are delivered 'as a service' to external customers using Internet technologies" - Gartner Inc.

Getting on the Cloud
Amazon Web Services No technical issues How to pay for the services?
Credit Card? Prepaid credit card? Prepay for Amazon credit? Get billed by Amazon? .......

“All Aboard” the Cloud
Contacted Amazon Applied for a research grant with Amazon Got a small grant
Started building...

Security
Users authenticate through Phaeton Login Node LDAP Authentication
Encrypted Communications 128 bit AES encryption for the data link 160 bit SHA1 checksum for both the data and
control channels

Data Concerns
Amazon gives choice of location EU-WEST-1A & EU-WEST-1B
Data not "stored" in the cloud Computation only in the cloud

What else?
AMD vs INTEL Licensing Tuning
Cost comparison Currently appears more expensive than local
resources Approx. €9,500 per month for AWS Costs have recently fallen

The Benefits
Immediately available resources "Once off" usage charge for resources Relatively quick to set up Easy to maintain Viable option for occasional large scale single
jobs

Future Plans
UCD “Cloud” Incorporating existing local resources Access to multiple public cloud resources Seamless service provision Automated “cloud bursting”
