IMPORTANT

The PPA for Ubuntu packages has been moved to ppa:dcdillon/cpuaff.

Short Description

cpuaff is a C++ library that abstracts CPU affinity settings for multiple platforms. It is a header-only library on some platforms. Other platforms are supported using hwloc. The project aims to fully support all platforms as header-only eventually.

Simple Example

#include<cpuaff/cpuaff.hpp>
#include<iostream>intmain(int argc, char *argv[])
{
cpuaff::affinity_manager manager;
if (manager.has_cpus())
{
cpuaff::cpu_set cpus;
manager.get_affinity(cpus);
std::cout << "Initial Affinity:" << std::endl;
cpuaff::cpu_set::iterator i = cpus.begin();
cpuaff::cpu_set::iterator iend = cpus.end();
for (; i != iend; ++i)
{
std::cout << "" << (*i) << std::endl;
}
std::cout << std::endl;
// set the affinity to all the processing units on// the first core
cpuaff::cpu_set core_0;
manager.get_cpus_by_core(core_0, 0);
manager.set_affinity(core_0);
manager.get_affinity(cpus);
std::cout << "Affinity After Calling set_affinity():"
<< std::endl;
i = cpus.begin();
iend = cpus.end();
for (; i != iend; ++i)
{
std::cout << "" << (*i) << std::endl;
}
return0;
}
std::cerr << "cpuaff: unable to load cpus." << std::endl;
