O SMP é suportado desde o OpenBSD 3.6, lançado em 2004.
Presumivelmente, o limite antigo era de 4 núcleos ou 16 núcleos.
A maneira mais fácil de obter suporte ao SMP é instalar o kernel bsd.mp
. Isso deve acontecer por padrão se o seu sistema tiver vários núcleos.
As of June, 2004, SMP (Symmetric MultiProcessor) support has been merged into the main OpenBSD development branch. At this time, the i386, amd64, mvme88k, sparc64, macppc and hppa platforms support SMP.
Starting with OpenBSD 3.6, OpenBSD/i386 supports most SMP (Symmetrical MultiProcessor) systems. To support SMP operation, a separate SMP kernel (bsd.mp) is included with the installation file sets.
Quais sistemas do OpenBSD suportam o SMP?
A separate SMP kernel, "bsd.mp", is provided with the install file sets. If multiple processors are detected at install time, is automatically installed as the default boot kernel, /bsd, and the single processor kernel is renamed /bsd.sp.
