The last decade witnessed a new era of software development that allows software developers to write applications independently of the target environment by packaging them along with their dependencies and environment variables inside containers. Numerous studies [1-2] have shown that containers are optimal for building and running applications reliably on Read more…
Storage is a crucial aspect of HPC clusters. Storage nodes are typically shared among multiple users, and are highly utilized – there isn’t a lot of unused space. The storage nodes also experience a lot of reads and writes – data is typically written, deleted, and written again multiple times. Read more…

Each of these steps is intrinsically simple and understandable by everyone: collecting is the process of gathering the necessary data, where this can be a temperature sensor, RAM usage counter, power consumption, or the number of Read more…
Service development, provisioning, operation and integration into large scale production infrastructures often suffers from a lack of quality assurance realization. This may result from the fact that the different actors involved are either not aware of the benefits of applying quality practices, or not keen to adhere to them as Read more…
