MIPS Speedup Calculation

5 R-type instructions are to be executed on our original 5-stage (scalar) pipelined processor. There are no dependencies of any kind among the instructions. If this same instruction sequence is executed instead on a degree-2 super-pipelined version…

How to require a minimum CPU speed for an Android app

I have written an Android app for signal processing that is computationally intensive. Certain algorithms that take a few seconds on a 2017 iPad take several minutes on an Acer B3-A40 (Android v7.0, 1.3GHz). I would like to limit the tablets and…

Computation Speed differs between OPL and Docplex

I've got a problem at solving an MIP with Docplex. The computation speed for my problem differs between 35 and 120 seconds while it is solved within 5 seconds using the OPL version. The model formulation does not differ between Python and OPL. Does…

What is the "spool time" of Intel Turbo Boost?

Just like a turbo engine has "turbo lag" due to the time it takes for the turbo to spool up, I'm curious what is the "turbo lag" in Intel processors. For instance, the i9-8950HK in my MacBook Pro 15" 2018 (running macOS Catalina 10.15.7) usually…

Is the Xcode simulator slower when using a newer simulated device?

I have a fairly old Mac, so I'm trying to find ways that I can speed up the Xcode simulator. I have an assumption that simulating older devices will be faster than newer ones. This assumption comes from the fact that older devices have less powerful…

Intructions vs cycles per second - what is actually measured in Hertz?

So I am going through some tutorials, and it seems they keep using "instructions" and "cycles" interchangeably, so now I am confused what is actually measured in Hertz (on the most basic level, without going into what the modern processors can do in…

MS-Windows scheduler control (or otherwise) -- test application performance on slower CPU?

Is there some tool which allows one to control the MS-Windows (XP-SP3 32-bit in my case) scheduler, s.t. a target application (which I'd like to test), operates as if it is running on a slower CPU. Say my physical host is a 2.4GHzv Dual-Core, but…

CPU speed changes by a multiply of 2 for short durations

I'm using a raspberry pi and I need really fast performance from my CPU for a certain process. To achieve that, I added isolcpus=3 to my kernel boot parameters, to isolate the core for this process only. From looking at /proc/interrupts, it seems…
