CPU Scheduling Simulator

COMMENTED ISSUE: Run class missing from latest build

m4dc4p — Fri, 25 Apr 2008 23:55:41 GMT

I downloaded the 1.0 release (100040.zip) and can't build. Logger.cs refers to the "Run" class which I cannot find. Also, a file named CpussDataContext.cs is missing from the Cpuss project - though maybe it is created by the SQL script?
Comments: ** Comment from web user: m4dc4p **

Digging further, it looks like these are files maybe created for Linq to SQL? I'm a newb at 2008 - can you give simple steps for recreating them?

UPDATED RELEASE: 1.0 RTW (Apr 08, 2008)

Thu, 10 Apr 2008 14:45:51 GMT

CPU Scheduling Simulator (CPUSS) 1.0 and CPUSS Report Generator (CPUSSRG) 1.0 are released!

A brief explanation of the files in this 1.0 release:

* CPUSS 1.0 (source) – includes full source and unit tests
* CPUSS 1.0 (binary) – includes release builds of CPUSS, and associated strategies
* CPUSSRG 1.0 (binary) – includes release build of the report generator tool
* CPUSS 1.0 (documentation) – HTML help file for CPUSS and associated strategies
* CPUSS (documentation) – a brief set of notes on how to use the framework, extend it, and how to use CPUSSRG

Please see README-cpuss.htm for build and setup information.

_Note: on 09/04/08 I removed the prebuilt binaries from the CPUSS 1.0 source code zip file to reduce the file size._
_Note: On 10/04/08 I replaced the compiled help file, some pages were not being loaded correctly._

What is CPUSS?

CPU Scheduling Simulator (CPUSS) is a framework that allows you to quickly and easily design and gather metrics for custom CPU scheduling strategies.

Features
CPUSS Report Generator (CPUSSRG)

Features

CPUSS records the following metrics about your scheduling algorithm:

Average process wait times
Idle CPU time
Busy CPU time
Wait time mean
Wait time standard deviation
Response time mean
Response time standard deviation
Turnaround time mean
Turnaround time standard deviation
Throughput stats
Throughput mean
For each process

Arrival time
Start time
Completion time
CPU activity
Burst time
Id
Priority
Wait time
Turnaround time
Response time

As well as the core features CPUSS also allows you to:

Define the processes to schedule
Auto generate the processes to schedule (varying burst time properties)
Log results to SQL Server
Hook into events

Simulation Started/Completed
Process Started/Preempted/Resumed/Completed

have also included the following strategies so far:

First Come First Served
Round Robin (time quantum can be defined)
Shortest Job First*
Priority First*
SJF with Priority Elevation rule (threshold can be defined)*

* indicates that the poll time of this strategy can be defined

CPUSS Report Generator (CPUSSRG)

CPUSSRG allows you to quickly and effeciently generate a report and view some of the key stats from the simulation (avg/std dev/var wait times, cpu utilization etc). You can run the simulation many times to get a broader picture of the data for further analysis.

The following command was used to generate the below (I have only shown a bit of the graph, there is much more info in the report than this):

CURRENT DIR>cpussrg /report:sjfe /outdir:C:\<user>\Desktop\reports /strategy:ShortestJobFirstExpert,10,60 /small:50 
/medium:50 /large:50 /repeat:20

Thank you

- CPUSS 1.0!!!!!!

CLOSED TASK: User manual

gbarnett — Tue, 08 Apr 2008 18:33:59 GMT

Finish the brief user notes for using CPUSS.

CLOSED TASK: License document

gbarnett — Tue, 08 Apr 2008 14:29:52 GMT

Include pdf version of the license used for CPUSS (Ms-PL).

CLOSED FEATURE: Add /window flag to CPUSSRG

gbarnett — Tue, 08 Apr 2008 14:27:12 GMT

Let the user define the window timeframe via the CPUSSRG tool.

Source code checked in

gbarnett — Tue, 08 Apr 2008 14:25:34 GMT

- Added /window flag to cpussrg.exe

CLOSED ISSUE: Relative paths for image files

gbarnett — Mon, 07 Apr 2008 23:16:14 GMT

Just noticed this after copy some output files to a different directory. Because the image files are all explicit moving them to another location breakes the image links, so they need to be made relative.

Source code checked in

gbarnett — Mon, 07 Apr 2008 23:15:56 GMT

- Fixed relative image paths

CLOSED FEATURE: Add custom window time frame for throughput to manual and automated process loads

gbarnett — Mon, 07 Apr 2008 23:11:20 GMT

Allow users to define a custom window timeframe in these scenarios.

CLOSED ISSUE: Resource names

gbarnett — Mon, 07 Apr 2008 23:11:20 GMT

Bring consistancy to the names of resource lookup strings, at the moment they vary too much.

Source code checked in

gbarnett — Mon, 07 Apr 2008 23:07:04 GMT

- Added custom throughput windows to Runner - Cleaned up Resources.resx

CREATED FEATURE: Add /window flag to CPUSSRG

gbarnett — Mon, 07 Apr 2008 22:52:01 GMT

Let the user define the window timeframe via the CPUSSRG tool.
