Linux 上的 R 会话 - 提交指向同一会话的多个批处理作业

[英]R Session on Linux - submit multiple batch jobs pointing to same session

原文 2020-01-24 16:22:12 3 2 r/ linux/ session

1) Is it possible to start R sessions on Linux (eg Rsession1) and submit multiple jobs in batch mode to the same R Session (eg job1 to Rsession1 and then later on based on user action submit job2 to Rsession1)? 1) 是否可以在 Linux 上启动 R 会话（例如 Rsession1）并以批处理模式将多个作业提交到同一个 R 会话（例如，job1 到 Rsession1，然后根据用户操作将 job2 提交到 Rsession1）？

This is equivalent to opening interactive R Session and submitting job1 and the user can submit job2 in same session (which will be available until the user closes interactive R session)这相当于打开交互式R会话并提交job1，用户可以在同一个会话中提交job2（直到用户关闭交互式R会话才可用）

2) Is it possible to start two R sessions on Linux (eg Rsession1 and Rsession2) and submit multiple jobs in batch mode but specify session-id during job submission? 2) 是否可以在 Linux 上启动两个 R 会话（例如 Rsession1 和 Rsession2）并以批处理模式提交多个作业，但在作业提交期间指定 session-id？

This is equivalent to opening two interactive R Sessions and submitting jobs to different R sessions by clicking on the window manually submitting the job.这相当于打开两个交互式 R 会话并通过单击窗口手动提交作业将作业提交到不同的 R 会话。

I'm not sure what your end goal is, but have you considered something like the futures package that will allow R to send work off to another thread to be completed?我不确定你的最终目标是什么，但你有没有考虑过像futures包这样的东西，它允许 R 将工作发送到另一个线程来完成？ That way the work can be done but doesn't lock up the main R session while the work is being completed.这样可以完成工作，但不会在工作完成时锁定主 R 会话。 This way, via the main R session, you could launch job1 and then while that was still being worked on, launch job2.这样，通过主 R 会话，您可以启动 job1，然后在仍在处理的时候启动 job2。

You can use save.image at the end of each job to store the workspace and load at the beginning of the following jobs to restore it.您可以在每个作业结束时使用save.image来存储工作区，并在以下作业开始时load以恢复它。 By choosing different file names the session-id could be specified.通过选择不同的文件名，可以指定 session-id。
