    • Example embodiments of the present invention includes systems and methods for implementing a scalable symmetric multiprocessing (shared memory) computer architecture using a network of homogeneous multi-core servers. The level of processor and memory performance achieved is suitable for running applications that currently require cache coherent shared memory mainframes and supercomputers. The architecture combines new operating system extensions with a high-speed network that supports remote direct memory access to achieve an effective global distributed shared memory. A distributed thread model allows a process running in a head node to fork threads in other (worker) nodes that run in the same global address space. Thread synchronization is supported by a distributed mutex implementation. A transactional memory model allows a multi-threaded program to maintain global memory page consistency across the distributed architecture. A distributed file access implementation supports non-contentious file I/O for threads. These and other functions provide a symmetric multiprocessing programming model consistent with standards such as Portable Operating System Interface for Unix (POSIX).
    • 本发明的示例性实施例包括使用同质多核服务器的网络来实现可扩展对称多处理(共享存储器)计算机体系结构的系统和方法。 所实现的处理器和存储器性能水平适用于运行当前需要缓存一致共享内存大型机和超级计算机的应用程序。 该架构将新的操作系统扩展与支持远程直接内存访问的高速网络相结合,以实现有效的全局分布式共享内存。 分布式线程模型允许在头节点中运行的进程在同一全局地址空间中运行的其他(工作)节点中分叉线程。 分布式互斥体实现支持线程同步。 事务性内存模型允许多线程程序在分布式架构上维护全局内存页面一致性。 分布式文件访问实现支持非争用的文件I / O线程。 这些和其他功能提供了与Unix(POSIX)的便携式操作系统接口等标准一致的对称多处理编程模型。

    • A biopsy cannula and a method are provided for capturing and retrieving a specimen of soft tissue for subsequent diagnostic evaluation. The biopsy cannula defines a passageway of non-circular cross-section. The cannula is inserted into target tissue and rotated about the longitudinal axis of the cannula. The non-circular cross-sectional shape of the passageway in the cannula helps the cannula grippingly engage the tissue and cause the tissue to rotate with the cannula. Regions of the tissue adjacent the distal end of the cannula will be subjected to torque and will be severed from tissue outside the cannula. The cannula may then be withdrawn with the severed core of target tissue therein. The exterior of the cannula may be generally rounded or cylindrical in shape.
    • 提供活检插管和方法用于捕获和取回软组织样本用于随后的诊断评估。 活检插管限定非圆形横截面的通道。 将插管插入目标组织并围绕插管的纵向轴线旋转。 套管中通道的非圆形横截面形状有助于套管夹紧地接合组织并使组织与套管一起旋转。 邻近套管远端的组织区域将受到扭矩的影响,并将从插管外部的组织切断。 然后可以用其中的目标组织的切断的芯取出套管。 插管的外部可以是大致圆形或圆柱形的形状。
