    摘要： A method for conveying a data packet received from a network to a virtual machine instantiated on a computer system coupled to the network, and a medium and system for carrying out the method, is described. In the method, a guest receive pointer queue of a component executing in the virtual machine is inspected in order to identify a location in a guest receive packet data buffer that is available to receive packet data. Data from the data packet received from the network is copied into the guest receive packet data buffer at the identified location. A standard receive interrupt is raised in the virtual machine. Thus, the kernel places the data packet received from the network into a memory space accessible to the virtual machine without any intervention by a virtual machine monitor component of the virtualization software.

    摘要： The present invention is directed to DNA polymerase fusion proteins with increased processivity and nucleic acid affinity. The invention includes a fusion protein comprising a nucleic acid-binding domain fused to a polymerase domain. The nucleic acid binding domain contains at least one nucleic acid binding motif, such as a DNA-binding motif or an RNA-binding motif. The nucleic acid binding domain preferably embodies an oligonucleotide/oligosaccharide binding (OB) fold, among other conformations. The invention further includes methods of synthesizing nucleic acids using the fusion proteins described herein.

    摘要： To generate a checkpoint for a virtual machine (VM), first, while the VM is still running, a copy-on-write (COW) disk file is created pointing to a parent disk file that the VM is using. Next, the VM is stopped, the VM's memory is marked COW, the device state of the VM is saved to memory, the VM is switched to use the COW disk file, and the VM begins running again for substantially the remainder of the checkpoint generation. Next, the device state that was stored in memory and the unmodified VM memory pages are saved to a checkpoint file. Also, a copy may be made of the parent disk file for retention as part of the checkpoint, or the original parent disk file may be retained as part of the checkpoint. If a copy of the parent disk file was made, then the COW disk file may be committed to the original parent disk file.

    摘要翻译： 要为虚拟机（VM）生成检查点，首先，当VM仍在运行时，会创建指向VM所使用的父磁盘文件的写时复制（COW）磁盘文件。 接下来，VM停止，VM的内存被标记为COW，VM的设备状态被保存到内存，VM被切换为使用COW磁盘文件，并且VM再次开始运行，大部分剩下的检查点生成 。 接下来，将存储在存储器中的设备状态和未修改的VM内存页保存到检查点文件。 另外，作为检查点的一部分，可以将父磁盘文件作为副本作为保留，也可以将原始的父磁盘文件作为检查点的一部分进行保留。 如果生成了父磁盘文件的副本，则COW磁盘文件可能会提交到原始的父磁盘文件。

    摘要： A source virtual machine (VM) hosted on a source server is migrated to a destination VM on a destination server without first powering down the source VM. After optional pre-copying of the source VM's memory to the destination VM, the source VM is suspended and its non-memory state is transferred to the destination VM; the destination VM is then resumed from the transferred state. The source VM memory is either paged in to the destination VM on demand, or is transferred asynchronously by pre-copying and write-protecting the source VM memory, and then later transferring only the modified pages after the destination VM is resumed. The source and destination servers preferably share common storage, in which the source VM's virtual disk is stored; this avoids the need to transfer the virtual disk contents. Network connectivity is preferably also made transparent to the user by arranging the servers on a common subnet, with virtual network connection addresses generated from a common name space of physical addresses.

    摘要： Selecting a master node in a group of computing nodes. Computing nodes exchange suitability messages, candidate messages, and master messages to indicate the state of each node. A deterministic algorithm based on scores and timings is executed by each computing node to encourage each node to select the same master node.
