Is it impossible to truly emulate a system if its actual clock speed is the same?

As I understand emulation a rule of the thumb says that a computer must be around a order of magnitude more powerful to emulate another system without resorting to tricks. This is because for every clock cycle of the system to be emulated, the host…

Advantages of block-based simulator versus equation-based simulator

I am mostly using Modelica, an equation-based simulator. I assume that block-based simulators like Simulink have their strengths and are better at some tasks, but I am wondering what those are. It seems like everything a block based simulator can…

Does the pigeonhole principle rule out the possibility of losslessly simulating a universe the size of our own?

Say you had a very powerful computer and wanted to run a completely lossless simulation of a universe approximately the same size as our own: $10^{80}$ particles. Each particle in the simulation has properties like velocity, mass, charge, etc.…

Particles-based models - Discrete or Continuous, why?

I have a theoritical question about particles-based simulator (Reeves,83). I don't know if my question is relevant and I apologize if not. On each frame, the system generate particles and attribute to it properties and behaviour (speed, velocity,…

Is the simulation of how a warehouse functions (eg Amazon) a discrete event simulation problem

If i wanted to write a piece of software that simulated a warehouse where typical warehouse procedures occur eg loading of trucks onto conveyors goods being transported around a warehouse by machines goods being packed by operatives goods being…

Simulating a combinatorial network

I have various Boolean functions in the sum of products format. I "convert" these via combinatorial logic synthesis into a combinatorial network as an And-Inverter Graph - therefore this network only consists of 2-input, 1-output And-Gates and…

Is there any hope for real "simulated machines" in our lifetime?

Without going into details about my life's story, here's the basic facts: I grew up with 386 and 486 and Pentium PCs running MS-DOS 5 (I believe), Windows 3.1 and Windows 95, a well as various game consoles from the 8-bit, 16-bit and 32-bit eras. I…

Prof Knuth's MIX computer - Card Reader and illegal characters

I'm reading through Knuth's "The Art of Computer Programming" volume 1 (3rd edition), with the goal of understanding the complete workings of his hypothetical MIX computer in order to implement MIX in software. Needless to say this is a long term…

How would one simulate the law of conservation of energy?

I'm new to computer science, but I've studied physics for a while. I'm just curious, if one wanted to make a simulation of the law of conservation of energy, on a large scale, how would it be done? Most simulations take shortcuts for objects off…
