当您选择任务时，存在错误的节点将被突出显示。
When you select the task, the offending node will be highlighted.
这个处理器首先记录上报计数器，接着完成此节点关联的任务实例。
This handler first pegs the escalation counter and then completes a task instance, associated with this node.
向下扩展就像退回操作，其中没有将主节点置于在线的任务。
Scaling down is like a failback operation without the task of bringing the primary node up.
此视图描述了运作节点及其关系，并确定反映任务需求的依赖，因而为企业定义和演进提供全部的环境。
This view describes operational nodes and their relationships, and identifies dependencies reflecting mission requirements, thus providing an overall context for enterprise definition and evolution.
这两个任务各与一个停止节点直接相连。
该任务也有一个开始节点，不过，这个节点是可选的，不会改变任务的执行语义，这个任务只有在该输入可用的情况下才会开始执行。
The task also has a start node, however, this node is optional and does not change the execution semantics of the task, which can only begin execution when the input is available.
故障转移：故障转移的基本任务保持相同：将处理切换到辅助节点，然后再切换回去。
Failover: the basic tasks of failover remain the same: switch processing to the secondary node and, later, switch back.
例如，如果业务模型中存在已知会导致技术实现挑战的映射节点，则应该将它们更改为任务。
For example, if there were mapping nodes in the business model that are known to cause technical implementation challenges, then they should be changed to tasks instead.
JPPF接受多个任务，并将之分配到不同的节点执行，最后再将结果重组成合适的格式。
JPPF is designed to take in a number of tasks, distribute their execution over the compute nodes, then recompose the results into the appropriate format.
树中的内部节点是采用ELSE分支的任务。
Internal nodes in the tree are tasks that take the ELSE branch.
研究人员让参与者回忆如学生会列出的即将上演的音乐剧，以及不同节点上完成的任务等小细节。
Those who took part were asked to recall small details, such as music ACTS listed to play at the students 'union and tasks completed at various points.
他给出了一个使用四个随需节点，并加入第五个附加节点的任务作为例子。
He gave the example of having a job use four on demand nodes, with five additional spot nodes being added.
所创建的流程的数量，要依据构成任务的阶段数量，以及逻辑节点的数量。
The number of processes that are created depends on the number of stages that compose the job, as well as the number of logical nodes.
这些节点是为轻量级的任务所用的，像自定义计算，文件系统的移动、创建目录、删除等等。
These nodes are meant for lightweight tasks like custom calculations, FileSystem move, mkdir, delete.
主节点收集结果，并继续分发任务，依此类推。
The master node assembles the results, further distributes work, and so on.
工作者节点处理这些小任务，把结果返回给主节点。
The worker node processes that smaller task, and passes the answer back to the master node.
您应当用一个直接连接到某个任务或子流程的开始节点，替换一个只使用开始节点作为输入的join。
You should replace a join that only has start nodes as input with a single start node that directly connects to a task or subprocess.
