Minimserver CPU Affinity

Nothing has changed since 2020. As it can be tricky to set this up, here are detailed step-by-step instructions.

1) Create a file named runjava.sh using a text editor. You can put this anywhere. For the rest of these instructions I will assume this file is in your home directory /home/your-user-name. If you want to run MinimServer on CPU core 2 (for example), this file should contain the following:

#!/bin/bash
exec taskset -c 2 java "$@"

2) Give the runjava.sh file executable permission by running this command:
chmod 755 /home/your-user-name/runjava.sh

3) Create a file named minimstart.conf using a text editor. This file must be in the minimserver/etc directory. If you have installed MinimServer in your home directory, the full path to this file will be /home/your-user-name/minimserver/etc/minimstart.conf. This file should contain the following:

java=/home/your-user-name/runjava.sh

4) Stop MinimServer and start it again.

5) To check that MinimServer is running on CPU core 2, run this command:
ps -eo psr,command | grep mserver

6) The output from this command should include a line similar to the following:
2 java -jar /home/your-user-name/minimserver/lib/mserver.jar --launchrc --set watch.view=log --nohup

7) The number '2' at the start of the line is the CPU core that is running MinimServer
