Description

Performance Data Visualization of Multiprocessor Systems. cpuplayer is a CLI stand-alone version of Barry2D , that provides animation for visually exploring performance issues based on multiprocessor utilization data. Features:

• Stand-alone video capabilities to play real-time or historical utilization data

• Supports CSV data format

• Toggled display of date and time information

• Toggled display of multicore IDs

• Toggled display of USER, SYSTEM and IDLE axes

• Full color performance zones

Build

The cpuplayer package comes in source code, C. To compile this for your system please execute the followings:

1. export OSTYPE=Darwin | Linux

2. make clean

3. make

4. execute the program: cpuplayer data/1cpu.ferrari4000

Usage

Play historical data

This will play historical data from one data file, called cpurec.T5220.noprocsets

$ cpuplayer data/cpurec.T5220.noprocsets

Play real-time data

This will run cpurec data recorder and pipe the results to cpuplayer directly to visualize data as soon as it is collected.

$ cpurec | cpuplayer 

Input Data

The cpuplayer expects the input data via command line arguments or directly piped to it, using a simple CSV format:

• timestamp: UNIX time
• cpuid: the CPU id
• User cpu percent utilization 0-100
• System cpu percent utilization 0-100
• Idle state cpu percent utilization 0-100

Examples

Solaris 10 Sybase OLTP workload

Case study which shows cpuplayer diplaying the performance advantages of enabling processor sets in Solaris 10 for a Sybase OLTP workload running on a Sun Entreprise T5220 with up to 32 virtual processors.

   

Future

Port cpuplayer to Rust. Pause option.
