process

问题 I have noticed that some cells take a long time to finish executing on my Jupyter Notebooks. When looking in the task manager, I see that the python process is only using up to about 4% of the CPU. I am using Python 3.6.2 I am on Windows but am using the "Bash on Ubuntu on Windows" terminal to launch the Jupyter notebook (maybe this helps). The processor is a Core i7 and the process is not using up all available RAM so it isn't a Swap memory problem. Basically, why is it being "throttled"

问题 I am having trouble calling a program with the Process class to start a program. The hierarchy to the executable is in under the bin directory while the current working directory needs to be under the lib directory. /project /bin a.out (this is what I need to call) /lib (this is where I need to be in order for a.out to work) I have set the WorkingDirectory = "path/lib" and the "FileName = "../bin/a.out" . However I am getting an error of: Unhandled Exception: System.ComponentModel

问题 I'm having a problem creating a inter-process communication for my python application. I have two python scripts at hand, let's say A and B. A is used to open a huge file, keep it in memory and do some processing that Mysql can't do, and B is a process used to query A very often. Since the file A needs to read is really large, I hope to read it once and have it hang there waiting for my Bs' to query. What I do now is, I use cherrypy to build a http-server. However, I feel it's kind of awkward

问题 On a couple of windows XP systems I've looked at, the "System Idle Process" always has PID 0, and the "System" process always has PID 4. In a Windows program which enumerates processes, is it safe to recognise these processes by these PIDs, or can they be different in some circumstances? 回答1: I have production code which assumes these PIDs are static, and it works on XP, Vista and Win 7. Not sure if it's the officially supported method though! Another couple of ways of approaching the problem
