Thread Pool vs Many Individual Threads

I'm in the middle of a problem where I am unable decide which solution to take. The problem is a bit unique. Lets put it this way, i am receiving data from the network continuously (2 to 4 times per second). Now each data belongs to a different, lets say, group. Now, lets call these groups, group1, group2 and so on. Each group has a dedicated job queue where data from the network is filtered and added to its corresponding group for processing. At first I created a dedicated thread per group which would take data from the job queue, process it and then goes to blocking state (using Linked

Python: How to determine subprocess children have all finished running

I am trying to detect when an installation program finishes executing from within a Python script. Specifically, the application is the Oracle 10gR2 Database. Currently I am using the subprocess module with Popen. Ideally, I would simply use the wait() method to wait for the installation to finish executing, however, the documented command actually spawns child processes to handle the actual installation. Here is some sample code of the failing code: import subprocess OUI_DATABASE_10GR2_SUBPROCESS = ['sudo', '-u', 'oracle', os.path.join(DATABASE_10GR2_TMP_PATH, 'database', 'runInstaller'), '

How to spawn a process and capture its STDOUT in .NET? [duplicate]

This question already has answers here: Capturing console output from a .NET application (C#) (8 answers) Closed 4 years ago. I need to spawn a child process that is a console application, and capture its output. I wrote up the following code for a method: string retMessage = String.Empty; ProcessStartInfo startInfo = new ProcessStartInfo(); Process p = new Process(); startInfo.CreateNoWindow = true; startInfo.RedirectStandardOutput = true; startInfo.RedirectStandardInput = true; startInfo.UseShellExecute = false; startInfo.Arguments = command; startInfo.FileName = exec; p.StartInfo =
