Hi,

Is this a mobile CPU?

Hi,

    CIAO version 0.6.1
    TAO version 1.6.1
    ACE VERSION: 5.6.1

    HOST MACHINE and OPERATING SYSTEM:
        Centrino Duo Core, Ubuntu 7.0.4-Feisty, kernel
 2.6.20-16-generic

    COMPILER NAME AND VERSION (AND PATCHLEVEL):
        gcc (GCC) 4.1.2

    THE $ACE_ROOT/ace/config.h FILE:
        #include "ace/config-linux.h"

    THE $ACE_ROOT/include/makeinclude/platform_macros.GNU FILE:
        no_hidden_visibility=1
        include
 /usr/local/ACE_wrappers/include/makeinclude/platform_linux.GNU


    CONTENTS OF
 $ACE_ROOT/bin/MakeProjectCreator/config/default.features:
     [there is no default.features file, but the gnuace and global
 features]
        qt=1
        fl=1
        tk=1
        xt=1
        cidl=1
        sctp=1
        zlib=1

    DESCRIPTION:

When i try to get the global scale factor implemented by ACE High_Res_Timer
Class, some times it returns the value 1000 and another time it returns
1833. Why this happens? 
i thought that it was stablished only one time by detecting hardwares
settings. If this value change at any time, how can i determine the correct
scale factor to be used?

cpuinfo file:

at boot time the parameter maxcpus was set to 1

Thanks for help
