摘要： A ProbeSystem for one or more Replicas is disclosed. For each replica, the Probe System includes a ProbeHead that updates a Head field in a Target Record pertaining to the Replica and a ProbeEcho that updates an Echo field in the TargetRecord. The Head field includes a time stamp and an epoch value. The Echo field includes a latency value and an epoch value. The fields are such that, during reporting, the ProbeHead can analyze the TargetRecord for the replica to determine the latency between one or more paths between the Replica and other Replicas. The ProbeSystem has a peer-to-peer shared nothing architecture and applies to a large class of high-replica, distributed and high-scale cloud storage systems and services.

摘要： Method, system, and programs for resolving data inconsistency in a distributed system having a plurality of replica instances. In response to a read request of at least one data element, a key-specific probability value for the at least one data element of the read request is retrieved. Based on the retrieved key-specific probability value and a system load of the distributed system, a self-healing probability of the at least one data element of the read request is computed. A self-healing transaction that includes the at least one data element of the read request is then generated based on the self-healing probability of the at least one data element. The generated self-healing transaction is further applied to at least some of the plurality of replica instances in the distributed system to resolve data inconsistency.

摘要： A compile server and a class loader are disclosed. During execution of a program, the class loader transmits a compile service request and a run time service request, including a program instruction, over a network to a compile server. The class loader receives native machine code compiled from the instruction, where the native machine code is received over the network. Once received, the native machine code is executed. The compile server receives the compile service request and the run time service request, including the program instruction, over a network from the class loader, compiles the instruction into native machine code, and transmits the native machine code over the network to be executed. The compile server generates a compile thread for each compile service requests and processes multiple compile threads concurrently.

摘要： A distributed garbage collection system and method is disclosed that is compatible with local ref-count or full garbage collection and that ensures that no local object's storage is deleted by the local garbage collector unless it is certain that there are no actual or potential remote references to that local object. The disclosed system and method are implemented in the context of a transparent distributed object system in which communications between objects in different processes are enabled by dedicated proxy objects that are linked to corresponding remote objects via a pair of transport objects. Additional proxy holder objects and proxy holder proxies ensure that objects for which third-party object references are passed (i.e., where one object in a first process passes a remote object in a second process a reference to a third object in a third process) are not collected until a direct link is established between the remote object in the second process and the third object in the third object space. As appropriate, secret number table pointers maintained by a local registrar for each object that has been accessed via a third party message are deleted, allowing the objects to be collected when there are no other actual or pending remote references to that object. The transport managers encrypt all inter-process messages so as to provide full capability security within the distributed system. This enables the disclosed garbage collection system and methods to operate under attack from misbehaving participants.

摘要： A system and method provides for variable target outputs from a compiler with only a single execution. The compiler includes a front end, a generic back end, and plurality of individual back ends that are dynamically loaded by the compiler during execution. The front end produces an abstract syntax tree which is then processed by the generic back end and the individual back ends to produce a number of back end trees, each adapted for a specific back end, and representative of the desired structure of the various target outputs, including target code files, or events. The generic back end traverses the abstract syntax tree, and on each node of the tree, invokes each back end that has a node of its back end tree attached thereto. The back end can then modify its own back end tree, and attach further back end nodes to other nodes of the abstract syntax tree. In turn the generic back end will invoke such added attached nodes, until all attached back end nodes on all the nodes of the abstract syntax tree have been processed. This results in completed back end trees for all of the back ends, requiring only a single pass of the front end to produce the abstract syntax tree. The individual back ends then process their respective back end trees to produce their target outputs. A look up operation is provided in the generic back end that returns one or more back end nodes in response to a request therefore specifying a node of the abstract syntax tree, and a family identification value of a back end node.
摘要翻译：一个系统和方法只提供一个执行的编译器的可变目标输出。编译器包括在执行期间由编译器动态加载的前端，通用后端和多个单独的后端。前端产生抽象语法树，然后由通用后端和各个后端处理，以产生多个后端树，每个后端树适用于特定后端，并代表各种目标输出的所需结构，包括目标代码文件或事件。通用后端遍历抽象语法树，并且在树的每个节点上调用具有其后端树的节点的每个后端。后端可以修改自己的后端树，并将进一步的后端节点附加到抽象语法树的其他节点。反过来，通用后端将调用这些附加的附加节点，直到抽象语法树的所有节点上的所有附加的后端节点都被处理。这导致所有后端的完成的后端树，仅需要前端的单次传递来产生抽象语法树。各个后端然后处理其各自的后端树以产生其目标输出。在通用后端中提供查询操作，其响应于因此指定抽象语法树的节点的请求返回一个或多个后端节点，以及后端节点的族标识值。
