sPAPI

Simple Scilab API for PAPI (Performance Application Programming Interface).

Installation

1. Install PAPI >=5.5.1
2. Run scilab in sPAPI directory
3. Compile sPAPI_register, sPAPI_tic, and sPAPI_toc functions from Scilab console using ilib_mex_build function:

ilib_mex_build('sPAPI', ['sPAPI_tic', 'sPAPI_tic', 'cmex'; 'sPAPI_toc', 'sPAPI_toc', 'cmex'; 'sPAPI_register', 'sPAPI_register', 'cmex'], [], [], '', '-lpapi', '', '');

Usage

1. Register hardware performance monitoring counters (PMC) using preset or native events:

>> sPAPI_register('FP_ARITH:SCALAR_SINGLE', 'L1D:REPLACEMENT', 'PAPI_L2_ICA')

2. Start counters:

>> sPAPI_tic

3. Read counters measurements:

>> sPAPI_toc

ans = [0  577  1123]

Comments

• The number of hardware counters available on the system defines the upper limit of counters you can register using sPAPI_register function.
• Not all hardware counters can be mixed and used simultaneously.

Future works

• Use new api_scilab 6.0 for sPAPI
