Hi,

 

From the look of it, i think the 32-bit license supports 16 cores? Could anyone kindly confirm? Thanks.

 

Output in the q console:

KDB+ 3.1 2014.03.27 Copyright (C) 1993-2014 Kx Systems<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>

w32/ 16()core 4095MB

 

Regards,

Hi Rui,

it can use all cores available. By default kdb+ starts in a singlethreaded mode. To use multiple cores, choose a multithreaded or multiprocess mode suitable for your application.

e.g.

For the 32bit version this is probably more interesting than multithreading, as each process has a usable address space of 2-4GB.

thanks
