    HIGHLIGHTS

    • 使用分布式并行计算功能加快仿真速度
    • 利用本地或分布式仿真模式实现资源的灵活利用
    • W1712 能够支持内置 SystemVue 数据流仿真器(W1461)的 8 个并发实例、独立的 SystemVue engine(W1711)和附加程序库

    这个 SystemVue ESL Design SoftwareW1712EP/ET SystemVue 分布式计算 8 件套可以加速执行和管理在分布式计算环境中所进行的多个参数化扫描仿真。它提供了十分全面的功能,包括创建、分配和提交作业,以及将结果作为一个单独的数据集返回 SystemVue。W1712 可以与 IBM Platform LSF 和 Univa Grid Engine 分布式计算软件结合使用,确保将各个作业自动分配给正确的资源,从而获得最高的应用性能和效率。通信系统架构师、验证工程师和基带产品设计人员使用 W1712,可以更快速地使用体系结构研究和验证套件,同时降低成本,并缩短获得结果的时间。

    加快仿真速度

    如果采用可堆叠的分布式计算 8 件套许可证政策,您可以通过扩大 IT 基础设施计算群的规模来提高仿真速度——从 8 个、16 个、24 个、32 个增加到理论上处理器的最大数量,显著提升并行仿真效率。在理论上,并行仿真速度与同时使用的处理器数量成正比。不过在实践过程中,仿真速度取决于仿真效率,而仿真效率又与多种环境因素紧密相关,例如网络流量和带宽、负载共享工具的性能、作业提交和分配的排序算法。

    为了最大限度提高仿真效率,SystemVue 提供了一个 “SimManager” 作业管理模块,以便确保 SystemVue Engine 与负载共享工具 Platform LSF 之间实现高效通信。

    W1712 Simulation Speed Up

    图 1. 使用多个处理器实施并行仿真,从而加快仿真速度。

    灵活的资源利用

    SystemVue 分布式计算 8 件套提供了灵活的操作模式,确保将不同类型的资源(本地或远程)分配给适当的仿真作业,提高用户的工作效率和资源利用率。这些模式是:

    • 无(使用 SystemVue 的内部仿真引擎进行本地仿真)
    • 本地并行(本地,但是要配合使用 SystemVue 的内部仿真引擎和附加的 W1711 SystemVue Engine 许可证)
    • IBM Platform LSF 和 Univa Grid Engine(远程)

    “本地并行”模式可以充分利用您本地的计算处理资源,并使用分配到的多个事件处理器并行执行仿真。“Platform LSF” 模式使用位于您的集群计算环境或计算服务器群中的远程资源。您可以在 SystemVue 图形用户界面(GUI)中轻松切换这些模式,根据您公司的 IT 资源更灵活地执行复杂的仿真任务。

    SystemVue 独立仿真引擎

    SystemVue 独立仿真引擎是其分布式仿真功能的核心,它能执行单纯的并行仿真,使处理器可以一边执行自己的作业,一边处理其他任务,两者互不影响。例如,一旦您开始执行一次 10 点仿真扫描,W1712EP/ET(分布式计算 8 件套)便会初始化 8 个并行仿真作业,让剩余的 2 个点排队等待处理,然后将这些作业自动分配给集群中可用的硬件资源。每个 SystemVue 引擎都可以单独运行,直至完成其作业。当所有处理都结束后,SystemVue 会收集结果并将它们集中到一个数据集中进行分析。

    主要应用

    在数字通信系统中,执行比特误码率(BER)仿真和测量任务需要在执行过程中更改很多参数,因此不仅代价非常高,而且极为耗时。通常说来,BER 仿真和测量需要数小时乃至数天的工程设计时间。如果此任务是用于进行一致性测试,以便验证系统是否符合标准规范,那么可能需要数周的时间。

    图 2. 在 AWGN 通道中仿真的 BER 与 Eb/N0 曲线(Eb/N0 从 -6 dB 扫描到 36 dB,以 2 dB 步进,使用接收机处理算法——前馈 AGC、差分关联帧同步、关联频率同步、相位评测、DD-PLL 频率跟踪、无 FEC)

    利用丰富的 SystemVue 无线应用程序库产品(LTE/A、WLAN 和雷达)和定制 C++ 建模功能,您可以将通信物理层系统设计和验证时间轻松缩短一半。

    应用实例

    • 已编码 QPSK 系统的 BER 与 Eb/No 瀑布曲线
    • 3GPP LTE/A 吞吐量与 SNR 测量
    • IEEE 802.11ac 高速无线 LAN BER 仿真
    • 雷达侦测概率扫描及瀑布曲线
    • 灵活的 OFDM 设计
    • SERDES 和其他

    为何购买 SystemVue 分布式计算 8 件套?

    网格管理器可以加快工作量处理并进行智能安排时间,在分布式、共享的 IT 环境中保证完成工作。通过 W1712EP/ET,SystemVue 可以更好地帮助企业客户向高性能技术计算转型,从而更快获得结果,提高基础设施利用率并降低运营成本。

    要求和推荐配置

    W1712EP/ET SystemVue 分布式计算 8 件套需要一个核心 SystemVue 平台(例如 W1461BP SystemVue Communications Architect)。如果 SystemVue 主环境是节点锁定的,则需要至少一个额外的 W1711 SystemVue Engine 浮动许可证。另外,任何添加的程序库,例如 W1905 雷达模型库,也必须获得浮动许可证。

    如何评测 W1712 SystemVue 分布式计算 8 件套?

    配置

    W1712 SystemVue 分布式计算 8 件套可以添加到下列 SystemVue 环境或软件套件中,并且仅提供浮动许可证配置。购买 W1712 的客户也可以考虑购买额外的仿真器浮动许可证(W1711EP/ET,可选)。
