IvanHoe 9.54b-TM00 x64 + Neither Option
IvanHoe 9.54b-TM01 x64 + Option 2
IvanHoe 9.54b-TM10 x64 + Option 1
IvanHoe 9.54b-TM11 x64 + Option 1 & 2
Option 1
Code: Select all
#if 0 /* about the 0.6 elo for the hasslings */ /* measure to UCI? */
if (!mtg)
{
rat = ((double) (TIME + 1)) / ((double) (OPP_TIME + 1));
if (rat > 2.0)
rat = 2.0;
if (rat < 0.5)
rat = 0.5;
if (rat > 1.0)
{
mult = ((int) (1024.0 * rat)) - 1024;
DESIRED_TIME += (mult * DESIRED_TIME) >> (10 + 2); /* max 1/4 */
}
else
{
mult = ((int) (1024.0 / rat)) - 1024;
DESIRED_TIME -= (mult * DESIRED_TIME) >> (10 + 2); /* max 1/4 */
}
}
#endif
Option 2
Code: Select all
#if 0
if (ROOT_DEPTH && ROOT_SCORE < -50)
DESIRED_TIME += DESIRED_TIME >> 3;
if (ROOT_DEPTH && ROOT_SCORE < -100)
DESIRED_TIME += DESIRED_TIME >> 3;
#endif
The code snippets are additional time management functions -- disabled by default in control.c.
Further note, this popcnt build is at at least 5% slower against single-core version non-popcnt Houdini -- yet on 4 cores, it's a different story.
