I don't have time to compete in tourneys. Chess is a hobby for me; nothing more.
I'm an IT Director and work very long hours plus traveling and such is not
possible most of the time. To tell you the truth I don't follow any of the
tourneys and don't know anything about them other than the CCT tourneys I
joined.

Yes. It will run on a single processor but only utilize one thread unless it's
an Intel HT. It detects two processors and set's it to CPU(2). If you do not
pass the number of CPU's you want to use it will detect how many CPU's and use
all of them.


void main( int argc, char **argv ) {
int i;
   char iargv[1024];
SYSTEM_INFO systemInfo;
GetSystemInfo( &systemInfo );
   System.ProcessorCount = systemInfo.dwNumberOfProcessors;
   System.ProcessorToUse = System.ProcessorCount;
   if ( (sLogFile = fopen("storm.log","w")) == NULL )
      Print( 1,"Could not open storm.log. Logging disabled" );
   else
      Print( 1,"Logging enabled" );
for ( i=1;i< argc )
            sscanf( argv[i],"%d",&System.ProcessorToUse );
if ( System.ProcessorToUse < 1 )
            System.ProcessorToUse = 1;
         if ( System.ProcessorToUse > System.ProcessorCount )
            System.ProcessorToUse = System.ProcessorCount;
}
}
ShowVersion( );
   PrintEx( 15,"\nUsing %d of %d processors\n",System.ProcessorToUse,
System.ProcessorCount );
Print( 3,"\n" );
Print( 3,"Type \"help\" to display the help file.\n" );
Print( 3,"\n" );
   Initialize( );
   StateMachine( );
exit( 0 );

That's correct. That was my first version which did not utilize multiple CPU's.
I do believe it beat tscp in all CCT's I entered. Check the date of it. You can
see how long ago that version was released. Because I choose not to release the
newer version of Storm has no relevance on it being a crafty clone.

Sorry, have not had the time to update my website. There are a few dead links,
which I will hopefully have time to work on in the near future.
