问题 Context: Process-1 is executing on core-0. Core-1 is idle. Now, process-1 uses sched_setaffinity() to change its CPU affinity as core-1. Question: Which kernel function(s) migrate the process-1 to execute on core-1? 回答1: Here is the call sequence starting from the sched_setaffinity system call entry point in the kernel: sys_sched_setaffinity. sched_setaffinity. __set_cpus_allowed_ptr. In the last function, there are two cases as shown in the code at line 1101: if (task_running(rq, p) || p-

问题 I'm learning about the scheduler and trying to print all runnable proceeses. So I have written a kernel module that uses the for_each_process macro to iterate over all processes, and prints the ones at "runnable" state. But this seems like a stupid (and inefficient) way of doing this. So I thought about getting a reference to all running queues and use their Red-Black-Tree to go over the runnable processes, but couldn't find a way to do this. I have found out that there is a list of sched

问题 I have a batch file which in turn calls VB Script. The task of the VBScript contains a macro whose job is to login into the Oracle db, run few queries, fetch the output in Excel sheet and then it performs other functions. The script is running fine in the scheduler when using the "Run only when user is logged in" option but it doesn't run when "Run whether user logged in or not" option is selected. I tried all the options suggested here in previous posts but none of them worked. 回答1: I

问题 Objective: prevent schedule from logging every time it runs. Background: I am using the logging and schedule libraries in a python project. My log file contains information about the physical state of a instrument run by a Raspberry Pi, and is updated every 10 seconds. I use the schedule library to schedule that periodic log. Here is the limited documentation I have found for schedule . The Problem: The schedule library logs this statement, every time it runs a job. 2016-06-29 09:01:51,022

问题 I'm wondering if its possible to create some kind of generic list of actions/funcs, each with different in/out params. The reason I need this is I have an executer who's job is getting data from an API, each of the methods in that executer goes to a different path in that API, and I want to be able to schedule those requests so I won't overload that API (they will just block me if I pass their threshold of requests). So each time a method in that executer is called, I will add that method and
