One particular scenario accommodated by SpeQuloS is the use of cloud (specifically cloud spot) instances as a source of durable CPU resources to buttress a DG, coupled with a task duplication strategy using cloud resources to mitigate the tail problem inherent to DGs.
In Section 'Buttressing desktop grids through cloudbursting', the architecture of a hybrid cloud-based DCI based on a DG buttressed with durable CPU resources to support two experimental use cases is introduced.
In the project "Optimal Scheduling of Scientific Application Workflows for Cloud-augmented Grid Infrastructures" (OSCA) [31], the authors of this article have investigated a similar scenario: the performance enhancement of DG applications obtained by buttressing the DG infrastructure with durable cloud resources.
In the experimental platform, durable cloud resources were sourced from an experimental cloud infrastructure at the University of Westminster: a private Openstack-Nova cloud consisting of 30 CPU cores, in contrast to the cloud spot instances assumed in SpeQuloS.
We first present a body of research showing that positive emotions broaden cognition and behavioral repertoires, and in so doing, build durable biopsychosocial resources that support coping and flourishing mental health.
To make these changes durable, the resources currently devoted to enforcing repressive policies must be redirected to prevention, harm reduction, treatment and care.
Specifically, positive emotions broaden our attention and thinking, enhance resilience, and build durable personal resources, which fuel more positive emotions in the future.
In 1999, the base year (see Fig. 9), resources, durable manufacturing and TCU accounted for the largest shares of overall pollution emissions.
Assuming EMIs do not change from their 1999 values, it is projected that CO emissions produced by durable manufacturing and resources will drop significantly while TCU remains the leading producer of NH3, NO x and SO2 emissions (see Fig. 10).
According to the forecasted emission under 1999 fixed EMIs, CO emissions produced from durable manufacturing and resources experience a considerable decrease while TCU remains the important contributor to emissions of NH3, NO x and SO2.
