We have a single threaded application which is restricted by CPU usage even though there are multiple CPUs on the server, hence leading to significant performance issues. Is it possible to merge / combine multiple CPUs at OS level so it appear as a single CPU for the application? (6 Replies)

BUS_BIND_INTR(9) BSD Kernel Developer's Manual BUS_BIND_INTR(9)
NAME
BUS_BIND_INTR, bus_bind_intr -- bind an interrupt resource to a specific CPU
SYNOPSIS
#include <sys/param.h>
#include <sys/bus.h>
int
BUS_BIND_INTR(device_t dev, device_t child, struct resource *irq, int cpu);
int
bus_bind_intr(device_t dev, struct resource *irq, int cpu);
DESCRIPTION
The BUS_BIND_INTR() method allows an interrupt resource to be pinned to a specific CPU. The interrupt resource must have an interrupt han-
dler attached via BUS_SETUP_INTR(9). The cpu parameter corresponds to the ID of a valid CPU in the system. Binding an interrupt restricts
the cpuset(2) of any associated interrupt threads to only include the specified CPU. It may also direct the low-level interrupt handling of
the interrupt to the specified CPU as well, but this behavior is platform-dependent. If the value NOCPU is used for cpu, then the interrupt
will be ``unbound'' which restores any associated interrupt threads back to the default cpuset.
Non-sleepable locks such as mutexes should not be held across calls to these functions.
The bus_bind_intr() function is a simple wrapper around BUS_BIND_INTR().
Note that currently there is no attempt made to arbitrate between multiple bind requests for the same interrupt from either the same device
or multiple devices. There is also no arbitration between interrupt binding requests submitted by userland via cpuset(2) and
BUS_BIND_INTR(). The most recent binding request is the one that will be in effect.
SEE ALSO
BUS_SETUP_INTR(9), cpuset(2), device(9)
HISTORY
The BUS_BIND_INTR() method and bus_bind_intr() functions first appeared in FreeBSD 7.2.
