Elastic Provisioning of Virtual Machines for Container Deployment

Abstract: Docker containers enable to package an application together with all its dependencies and easily run it in any environment. Thanks to their ease of use and portability, containers are gaining an increasing interest and promise to change the way how Cloud platforms are designed and managed. For their execution in the Cloud, we need to solve the container deployment problem, which deals with the identification of an elastic set of computing machines that can host and execute those containers, while considering the diversity of their requirements.In this paper, we provide a general formulation of the Elastic provisioning of Virtual machines for Container Deployment (for short, EVCD) as an Integer Linear Programming problem, which takes explicitly into account the heterogeneity of container requirements and virtual machine resources. Besides optimizing multiple QoS metrics, EVCD can reallocate containers at runtime, when a QoS improvement can be achieved. Using the proposed formulation as benchmark, we evaluate two well-known heuristics, i.e., greedy first-fit and round-robin, that are usually adopted for solving the container deployment problem.

Scalable parallel collision detection simulation

Abstract: Several simulations for parallel collision detection have been suggested during the last years. The algorithms usually greatly depend on the parallel infrastructure and this dependency causes in many times non-scalability performance. The dependency also harms the portability of the simulation. This paper suggests a scalable and portable parallel algorithm for collision detection simulation that fits both clusters and MPI machines.

nf-core: Community curated bioinformatics pipelines

Abstract: The standardization, portability, and reproducibility of analysis pipelines is a renowned problem within the bioinformatics community. Bioinformatic analysis pipelines are often designed for execution on-premise, and this inevitably leads to a level of customisation and integration that is only applicable to the local infrastructure. More notably, the software required to run these pipelines is also tightly coupled with the local compute environment, and this leads to poor pipeline portability, and reproducibility of the ensuing results - both of which are fundamental requirements for the validation of scientific findings. Here we introduce nf-core, a framework that provides a community-driven platform for the creation and development of best practice analysis pipelines written in the Nextflow language. Nextflow has built-in support for pipeline execution on most computational infrastructures, as well as automated deployment using container technologies such as Conda, Docker, and Singularity. Therefore, key obstacles in pipeline development such as portability, reproducibility, scalability and unified parallelism are inherently addressed by all nf-core pipelines. Furthermore, to ensure that new pipelines can be added seamlessly, and existing pipelines are able to inherit up-to-date functionality the nf-core community is actively developing a suite of tools that automate pipeline creation, testing, deployment and synchronization. The peer-review process during pipeline development ensures that best practices and common usage patterns are imposed and therefore, adhere to community guidelines. Our primary goal is to provide a community-driven platform for high-quality, excellent documented and reproducible bioinformatics pipelines that can be utilized across various institutions and research facilities.

Method of using dynamic database to improve telephone number portability

Abstract: A system for providing telephone number portability within a structurally distributed telephone system by providing an address capture database (ACDB) for local exchange carriers (LECs) wherein a new number (NN) is stored in the ACDB if the NN is a physical address served by a LEC and the NN corresponds to a dialled directory number (DN) ported into or located within the LEC.

Method for providing a virtual execution environment on a target computer using a virtual software machine

Abstract: A system and method for providing application program portability and consistency across a number of different hardware, database, transaction processing and operating system environments. In the preferred embodiment, the system includes a plurality of processes for performing one or more tasks required by the application software in one or more distributed processors of a heterogenous or "target" computer. In a run-time mode, program code of the application software is pre-processed, compiled and linked with system interface modules to create code executable by a operating system of the target computer. The executable code, which includes a number of functional calls to the processes, is run by the operating system to enable the processes to perform the tasks required by the application software. Communications to and from the processes are routed by a blackboard switch logic through a partitioned storage area or "blackboard".
