Abstract: According to some embodiments, a system comprises a work load management module and a plurality of datacenter pods communicatively coupled by a network. The data center pods include a first datacenter pod and a second datacenter pod. The work load management module receives a request to migrate a datacenter application from a first datacenter pod to a second datacenter pod. The work load management module retrieves a first pod environment configuration and a second pod environment configuration and automatically determines one or more differences between the first pod environment configuration and the second pod environment configuration. The work load management module modifies the datacenter application based on the one or more differences to be operable in the second datacenter pod and migrates the datacenter application to the second datacenter pod.

Abstract: An internal combustion engine including a two-stage turbocharger configuration is described. Located between the turbines of the two-stage turbocharger may be an oxidation catalyst and a passive NOx adsorber or an oxidation catalyst and an SCR device. An exhaust path extending from an engine body of the internal combustion engine to the second turbine of the two-stage turbocharger configuration may also include one or more hydrocarbon sources or one or more ammonia sources. A bypass valve arrangement may permit decreased flow through the first stage of the two-stage turbocharger arrangement as well as one or more of the elements positioned between the turbines of the two-stage turbocharger.
