Comprehensive Performance Isolation through Bias Resource Management for Public Clouds

您好,我在host中执行splitlock ,可以通过perf stat -e r10f4或 perf stat -e cpu/event=0xf4,umask=0x10/ 检测到。但是我把splitlock放在vm中执行,使用perf就检测不到了
bool detect()
{
timestamp_t now = get_timestamp();
if (now - this->last_time < this->interval)
return false;
this->last_time = now;
vector cpu_cachemiss = this->get_cpu_cachemiss();
for (int socket = 0; socket < nr_sockets; socket++)
{
map<string, MemUsage> vm_memusage = this->get_vm_memuage(socket, cpu_cachemiss);
SocketMemUsage socket_memusage = this->get_socket_memusage(socket, this->vm_memusage[socket]);
this->vm_memusage[socket] = vm_memusage;
this->socket_memusage[socket] = socket_memusage;
this->push_usage(socket, vm_memusage, socket_memusage);
}
DEBUG_LOG(">>> detected...");
return true;
}
是未完成??
您好,请问您采集polluter的CPI是用什么方式采的呢?我采集出来运行alita以后polluter的CPI反而降低了
我测试了一下splitlock对parsec的干扰,发现除了can以外,其他的workload的干扰效果都达不到预期,其中fs,x264,sc的运行时间在干扰情况下都不到单独运行的1.5倍。我的polluter和victim都分配了4个核,内存为4G,位于两个socket上,是否是我的虚拟机配置问题?
