摘要： Computer systems attempt to manage resource pools of a dynamic number of similar resources and work tasks in order to optimize system performance. Work requests are received into the resource pool having a dynamic number of resources instances. An instance-throughput curve is determined that relates a number of resource instances in the resource pool to throughput of the work requests. A slope of a point on the instance-throughput curve is estimated with stochastic gradient approximation. The number of resource instances for the resource pool is selected when the estimated slope of the instance-throughput curve is zero.

摘要： A parallelism policy object provides a control parallelism interface whose implementation evaluates parallelism conditions that are left unspecified in the interface. User-defined and other parallelism policy procedures can make recommendations to a worker program for transitioning between sequential program execution and parallel execution. Parallelizing assistance values obtained at runtime can be used in the parallelism conditions on which the recommendations are based. A consistent parallelization policy can be employed across a range of parallel constructs, and inside recursive procedures.

摘要： A profiler manager may attach and detach profilers from a running application. A profiler may be detached through a two step process where the profiler is sealed from communicating with the running application, then an evacuation step where the application is able to complete any responses that are pending. While the profiler is in the evacuation phase, another profiler may be attached to the application. Messages to the evacuating profiler may be captured and directed to the proper profiler.

摘要： A host intercepts calls between two executables and determines whether the calls are permissible according to the host's security model which can be identify based, such as user identity based—for instance, mapping access rights within a specific data base user context to database object access. Such an identity security model differs from a common language runtime security model where managed code uses Code Access Security to prevent managed assemblies from performing certain operations. Managed assemblies registered with the host are host objects from the host's perspective for which access rights can be defined via security rules, such as are defined for individual user identities. A host can decide access between managed executables based on the host's identity based access rules by trapping any cross assembly calls and deciding whether such calls should proceed or be blocked from taking place based on the corresponding identity security settings.
摘要翻译： 主机拦截两个可执行文件之间的调用，并根据主机的可以识别的安全模型（例如基于用户身份的特定数据库用户上下文中将访问权限映射到数据库对象访问）来确定是否允许呼叫。 这种身份安全模型与公共语言运行时安全模型不同，托管代码使用代码访问安全性来防止托管程序集执行某些操作。 与主机注册的托管程序集是主机视角的主机对象，可以通过安全规则定义访问权限，例如为各个用户身份定义的对象。 主机可以基于主机的基于身份的访问规则来决定托管的可执行文件之间的访问，通过捕获任何交叉程序集调用，并根据相应的身份安全设置来确定这些呼叫是应该继续还是被阻止发生。

摘要： Fine-grained parallelism within isolated object graphs is used to provide safe concurrent operations within the isolated object graphs. One example provides an abstraction labeled IsolatedObjectGraph that encapsulates at least one object graph, but often two or more object graphs, rooted by an instance of a type member. By encapsulating the object graph, no references from outside of the object graph are allowed to objects inside of the object graph. Also, the encapsulated object graph does not contain references to objects outside of the graphs. The isolated object graphs provide for safe data parallel operations, including safe data parallel mutations such as for each loops. In an example, the ability to isolate the object graph is provided through type permissions.

摘要： A profiler may be detached from an actively running application by first sealing communications between the application and profiler, then evacuating the profiler by waiting for any profiler-modified or instrumented code to complete execution, profiler runtime code to complete execution, cleaning up any residual items from the profiler, and shutting down the profiler. The profiler may be operational in many different environments, including a managed environment such as a virtual machine and those environments having just in time compiling of executable code.

摘要： Particular portions of program execution data are specified and organized in semantic groups. A grouping expression written in a transformation syntax language specifies a pattern and a replacement, for grouping performance data samples. An exception to the pattern can also be specified. In response to the grouping expression, a cost accounting shows groups and their costs. The grouping expression may operate on names and/or name-associated characteristics such as private/public status, author, directory, and the like. Samples may represent nodes in a directed acyclic graph memorializing call stacks or memory allocation. Grouping expressions are used to group nodes and consolidate costs by various procedures when making modified sample stacks: clustering-by-name, entry-group-clustering, folding-by-name, a folding-by-cost. An entry group clustering shows at least one entry point name while avoiding unwanted detail.

摘要： A compiler that completes compilation upon identifying unresolvable input during compilation instead of aborting compilation. This can be accomplished by inserting an exception-throwing instruction, and/or handlers in place of the unresolvable input in the compiled code output. If the section of the compiled code containing the inserted exception throwing instruction is later executed, an exception is thrown and/or handled. Compilation of code from a trusted source can be completed without inserting an exception throwing instruction when the code has only suspected but unverifiable problems.

摘要： A system and method of providing edit and continue support in a software program debugging environment. “Edit and continue” support allows a user (e.g., programmer and/or developer) to update the code and/or data structure(s) of an executing program while it is running. After the user has finished editing their code and resumes execution, an integrated development environment (IDE) propagates the edit(s) into a common language runtime (CLR) environment before continuing. Therefore, from the CLR environment's perspective, an edit is a block of intermediate language code (IL) and/or metadata that is inserted into a running process. The IDE can facilitate: determining “legality” of an edit; building the edit; sending the edit to the CLR environment; and/or, facilitating the CLR environment switch execution to the edited code.
摘要翻译： 在软件程序调试环境中提供编辑和继续支持的系统和方法。 “编辑和继续”支持允许用户（例如，程序员和/或开发者）在运行程序时更新执行程序的代码和/或数据结构。 用户完成编辑代码并恢复执行后，集成开发环境（IDE）将编辑传播到公共语言运行时（CLR）环境中，然后再继续。 因此，从CLR环境的角度来看，编辑是插入到正在运行的进程中的中间语言代码（IL）和/或元数据块。 IDE可以方便：确定编辑的“合法性”; 编辑编辑; 将编辑发送到CLR环境; 和/或促进CLR环境切换到编辑代码的执行。
