参考 Tensorflow学习——Eager Execution - 云+社区 - 腾讯云 TensorFlow's eager execution is an imperative programming Eager execution supports most TensorFlow operations and GPU acceleration. Note: Some models may experience increased overhead with eager execution enabled. You can use tf.summary to record summaries of variable in eager execution. performance is comparable to tf.function execution.
通过参数 spark.sql.execution.useObjectHashAggregateExec 来控制是否使用 object-hash-based 聚合,默认为 true。
tf.contrib.summary 与 Eager Execution 和 Graph Execution 环境兼容。 编写兼容的代码为 Eager Execution 编写的相同代码在 Graph Execution 期间也会构建图。 一旦通过 tf.enable_eager_execution 启用了 Eager Execution,就不能将其关闭。要返回到 Graph Execution,需要启动一个新的 Python 会话。 最好同时为 Eager Execution 和 Graph Execution 编写代码。 这样,既可以获得 Eager Execution 的交互式实验和可调试性功能,又能拥有 Graph Execution 的分布式性能优势。

二、Spark Adaptive Execution提出的相关解决方案 1、自动设置Shuffle Partition数量 Shuffle的过程是先通过Shuffle Write将各个分区的数据写到磁盘 spark.sql.adaptive.shuffle.targetPostShuffleInputSize来设置合并的阀值,默认为64M 只会合并小的分区,太大的分区并不会进行拆分 开启方式: spark.sql.adaptive.enabled=true:启动Adaptive Execution spark.sql.adaptive.skewedPartitionRowCountThreshold 的同时大于各 Partition 行数中位数与该因子的乘积,则它会被视为倾斜的 Partition 三、总结 Adaptive Execution 参考资料 http://www.jasongj.com/spark/adaptive_execution/ https://github.com/Intel-bigdata/spark-adaptive
应用中发生的所有特定事件(event)便会被记录下来,并支持将其保存在文件中以备后续分析,这个工具由谷歌工程师Dmitry Vyukov提出设计方案并实现,并在Go 1.5版本发布时加入Go工具链,这个工具被称为Go Execution

机器码是通过各种二进制表示的一串可以被计算机直接运行的指令,这种也叫机器语言,通常用010110这种来表示。虽然容易被计算机理解并且执行速度快,但是与我们所有的语言相关太大,并且维护成本巨大。

Execution Environment and Memory Model D.2.1. Execution Environment The CUDA execution model is based on primitives of threads, thread blocks, and When a kernel function is invoked the grid's properties are described by an execution configuration, Execution of a thread block is not considered complete until all launches by all threads in the block When a parent thread block launches a child grid, the child is not guaranteed to begin execution until
