What is the main difference (advantages / disadvantages) between Simulink Desktop Real-Time (SLDRT) kernel and Simulink Real-Time(SLRT) kernels? Do we use both of the for real-time (External Mode) applications, i.e. PID-Control? or not.

Simulink Desktop Real-Time (SLDRT) kernel is installed with the desktop OS (Mac or Windows). It is limited to using a single cpu core. Simulink Real-Time (SLRT) kernel runs on a dedicated computer so it will be able to leverage multicore platforms.
They are both able to use external mode type features (tunable parameters etc). The I/O offerings are slightly different (SLRT supports use of FPGAs).
