# 深入了解K8S中的numa nodes per socket 在Kubernetes(K8S)集群中,针对各种应用程序的部署和管理,可以使用numa nodes per socket来优化性能。numa nodes per socket是指每个CPU插槽中的NUMA节点数,可以帮助我们更好地利用硬件资源,提高应用程序的性能和效率。 ## 流程概述 下面是实现numa nodes per socket的流程概述...
setsockopt(socket,SOL_S0CKET,SO_RCVBUF,(char *)&nZero,sizeof(int)); 1. 2. 7.一般在发送UDP数据报的时候,希望该socket发送的数据具有广播特性: BOOL bBroadcast=TRUE; setsockopt(s,SOL_SOCKET,SO_BROADCAST,(const char*)&bBroadcast,sizeof(BOOL)); 1. 2. 8.在client连接服务器过程中,如果处于非...
Provides information on configuring the number of NPS (NUMA per socket) nodes. To access the NUMA nodes per socket setting, select Advanced AMD CBS DF Common Options Memory Addressing NUMA Nodes Per Socket NPS1 Socket . NUMA Nodes Per Socket Settings...
NUMA nodes per socket (NPS)DF Common Options → Memory Addressing → NUMA nodes per socket = NPS4这里根据实际情况设置为 1、2、4。设置为1时是 8 内存通道 interleaving,每个 NUMA 内带宽最高,延迟最大;设置为 4 时是 2 内存通道 interleaving,每个 NUMA 内带宽最小,延迟最小。若设为Auto,会根据当...
NUMA 的开启与配置,可以通过 BIOS 来搞(别问我 linux 内核里面开启关闭 NUMA 是怎么弄的,没研究,不会),参考《PowerEdge: NUMA Nodes per Socket》(参考文献 11)。 通过配置 Nodes Per Socket(NPS) 选型,来决定在什么粒度上进行 NUMA 划分。 拿Rome 来说,可选 NPS 选项及其含义如下(《NUMA Configuration sett...
Core(s) per socket: 6 //每个socket有6个cores Socket(s): 4 //共有4个sockets NUMA node(s): 4 //共有4个NUMA nodes Vendor ID: GenuineIntel CPU family: 6 Model: 45 Stepping: 7 CPU MHz: 1200.000 BogoMIPS: 4790.83 Virtualization: VT-x ...
Rome processors achieve memory interleaving by using Non-Uniform Memory Access (NUMA) in Nodes Per Socket (NPS). The below NPS options can be used for different workload types: NPS0 – This is only available on a 2-socket system. This means one NUMA node per system. Memory is interleaved...
Configuration options for NUMA nodes per socket. Attributes SERVICE_ALLOWED_VALUES_NPS0 A constant which can be used with the service_allowed_values property of a ShapeNumaNodesPerSocketPlatformOptions. SERVICE_ALLOWED_VALUES_NPS1 A constant which can be used with the service_allowe...

--ntasks-per-socket=14:每个 socket 绑定 14 个进程,等价于 --cpu-bind=sockets 或--cpu-bind=ldom --cpu-bind=none:不进行任何绑定 此时可以给 --cpu-bind 传入verbose(或者配置环境变量 SLURM_CPU_BIND=verbose)显示绑定结果,如: $ srun -n 2 -N 1 --cpu-bind=verbose,sockets ./exe cpu-bind=...
