A Linked Data scalability challenge : concept reuse leads to semantic decay
(ACM, 2015-06-28) - Conference item
The increasing amount of available Linked Data resources is laying the foundations for more advanced Semantic Web applications. One of their main limitations, however, remains the general low level of data quality. In this ...
A survey of self-healing systems frameworks
(2015-10) - Journal article
Rising complexity within multi-tier computing architectures remains an open problem. As complexity increases, so do the costs associated with operating and maintaining systems within these environments. One approach for ...
RBioCloud : a light-weight framework for bioconductor and R-based jobs on the Cloud
(2014-10-02) - Journal article
Large-scale ad hoc analytics of genomic data is popular using the R-programming language supported by over 700 software packages provided by Bioconductor. More recently, analytical jobs are benefitting from on-demand ...
Cloud Services Brokerage : a survey and research roadmap
(IEEE Computer Society, 2015-06-27) - Conference item
A Cloud Services Brokerage (CSB) acts as an intermediary between cloud service providers (e.g., Amazon and Google) and cloud service end users, providing a number of value adding services. CSBs as a research topic are in ...
Minimising the execution of unknown Bag-of-Task jobs with deadlines on the Cloud
(ACM, 2016-06-01) - Conference item
Scheduling jobs with deadlines, each of which de nes the latest time that a job must be completed, can be challenging on the cloud due to incurred costs and unpredictable performance. This problem is further complicated ...
An academic’s observations from a sabbatical at Google
(2018-09) - Journal article
How experiences gained in industry can improve academic research and teaching.
Simplified cloud instance selection
(ACM, 2018-04-23) - Conference item
Cloud computing delivers computational services to anyone over the internet. The cloud providers offer these services through a simplified billing model where customers can rent services based on the types of computing ...
Seastar: a comprehensive framework for telemetry data in HPC environments
(ACM, 2017-06-27) - Conference item
A large number of 2nd generation high-performance computing applications and services rely on adaptive and dynamic architectures and execution strategies to run efficiently,resiliently, and at scale on today’s HPC ...
Linking data, services and human know-how
(Springer, 2016) - Conference item
An increasing number of everyday tasks involve a mixture of human actions and machine computation. This paper presents the first framework that allows non-programmer users to create and execute workflows where each task ...
Algorithms for optimising heterogeneous Cloud virtual machine clusters
(IEEE, 2016-12-12) - Conference item
It is challenging to execute an application in a heterogeneous cloud cluster, which consists of multiple types of virtual machines with different performance capabilities and prices. This paper aims to mitigate this challenge ...
