摘要:
In this disclosure, techniques are described for more efficiently sharing resources across multiple virtual machine instances. For example, techniques are disclosed for allowing additional virtual machine instances to be supported by a single computing system by more efficiently allocating memory to virtual machine instances by providing page swapping in a virtualized environment and/or predictive page swapping. In one embodiment, a virtual memory manager swaps pages predicatively in and/or out of a paging pool based on information from a central processing unit (“CPU”) scheduler. In one embodiment, the CPU scheduler provides scheduling information for virtual machine instances to the virtual memory manager, where the scheduling information allows the virtual memory manager to determine when a virtual machine is scheduled to become active or inactive. The virtual memory manager can then swap-in or swap-out memory pages.
摘要:
A combination of the following three structures in a single molecule imparts a surprisingly broad range of beneficial effects in promoting and maintaining health. First, a strongly hydrophilic moiety, either a cation or anion or a polyhydroxyl group, with two or preferably three or more hydroxyl groups. Second, a lipophilic group, such as an alkyl chain of at least 8 carbons, and preferentially more, up to 18 or even 30-odd atoms in the chain. And third, a covalently reactive group, preferably with a strong tendency for binding to biosurfaces and biomolecules such as proteins, cell membranes, and/or nucleic acids, such as an epoxide, an acid anhydride, isocyanate or other reactive group(s) as herein defined.
摘要:
The present invention provides a method of manufacturing and distributing a cleaning solution for use in a vehicle washing facility. The method includes receiving pre-measured raw chemical material at a distributor's facility, diluting the pre-measured raw chemical material using a mixing apparatus at the distributor's facility to form a cleaning solution, packaging at least a portion of the cleaning solution into containers at the distributor's facility, and delivering at least one of the containers from the distributor's facility directly to the vehicle washing facility.
