Methods, systems, computer program products, and methods of doing business by improving the scheduling of execution of jobs for or by network-connected devices, thereby enabling the job execution process to scale more easily, efficiently, and effectively to support large numbers of devices and / or users. Examples of jobs include, but are not limited to, distribution of resources (including software, configuration information, images, and other types of content) to a device, fetching a device's inventory information, backing up a device's contents, and so forth. Jobs are programmatically scheduled based upon a specified time internal, according to a class of the requester. Only if an earliest start time after which the job may be executed for this requester has been reached will the job be executed; otherwise, the job execution is delayed. The disclosed techniques lessen the need for additional servers to handle spikes in processing load, reduce the likelihood of reaching system overload, and reduce the likelihood of cascading failures that may occur when systems are overloaded.

A distributed processing system includes plural nodes each provided with a processor and communicably connected to each other. A task information obtaining unit obtains antecedent dependency between tasks. A node information obtaining unit obtains a time constraint imposed on the tasks. A start time computing unit computes an absolute earliest start time at which a task can be started and an absolute latest start time allowed in order to complete the task within the time constraint, by referring to the time constraint. A node selector selects a destination node to which a target task not yet allocated to a node should be allocated, by referring to the absolute earliest start time and the absolute latest start time. A task placement unit causes the task to be executed in the selected node.

The technique of the invention sets a control start revolution speed Nstart to decrease with an increase in driver's power demand P* and with an increase in vehicle speed V (step S130), and motors an engine (steps S150 to S190). When a revolution speed Ne of the engine reaches the setting of the control start revolution speed Nstart, operation control of the engine starts (step S220). Such settings are ascribed to the following reasons. Setting a relatively small value to the control start revolution speed Nstart is preferable to trigger an early start of operation control of the engine and ensure quick output of power from the engine. In order to ensure reduction of vibrations of initial explosion and resulting reduction of potential vibrations arising at the time of starting the engine, on the other hand, setting a relatively large value to the control start revolution speed Nstart is preferable. The driver's sensitivity to the vibrations is lowered with an increase in vehicle speed V.

A low emission power generating apparatus which comprises a modified two-stroke diesel engine component and a modified turbocharger component which has a relatively low aspect ratio. The diesel engine component is a modification of a conventional two-stroke diesel engine design and includes an exhaust valve cam of unique design that has a cam profile which results in a later than-normal exhaust valve opening and an earlier-than-normal valve closing so that the time during which the exhaust valve remains open is shorter than normal, thereby causing a substantially greater volume of residual gases to remain in the combustion chamber following the scavenge stroke. This increase in the volume of the residual exhaust gases within the chamber leads to an increase in compression temperature and effectively increases the compression ratio and consequently the compression pressure. Because of the heat absorption capacity of these residual exhaust gases, the exhaust gases remaining in the chamber following the scavenge stroke tend to absorb combustion heat and thereby effectively reduce the peak combustion temperature. This reduction in peak combustion temperature advantageously results in the lower than normal formation of nitrogen oxide (NOx) and, therefore, allows advancement of the injection timing, while still maintaining the NOx emissions coming from the engine lower than those legislatively mandated. Advantageously, the advance in injection timing, which increases NOx emissions, by definition has the effect of also reducing particulate matter emissions. Thus, by increasing the volume of residual exhaust gases within the cylinder, substantial particulate matter emission reductions can be achieved, while at the same time maintaining NOx emissions well below mandated limits. The modified turbocharger component provides an additional charge of oxygen-rich air into the combustion chamber which effectively increases the compression pressure, which, in turn, leads to an earlier start of combustion because of the combustible mixture reaching its auto-ignition temperature at an earlier point in the cycle. This phenomenon leads to more thorough combustion of the fuel and also generally leads to higher exhaust temperatures. Higher exhaust temperatures, in turn, lead to a greater oxidation rate of the soluble organic fraction thus lowering the level of emission from the engine of undesirable particulate matter.

In a hybrid vehicle of the invention, in the event of specification that an exhaust treatment catalyst is in a preset adequate state at step S112, combustion control of an engine starts after a decrease of an intake pipe pressure P to a preset reference negative pressure Pref and reduction of an intake air flow into a cylinder of the engine by engine motoring.
