倚天710性能监控—DDR PMU子系统
1. 倚天710的ddr5子系统倚天710支持支持最先进的ddr5 dram，为云计算和hpc提供巨大的内存带宽。倚天710有8 ddr5通道（channel），每个die上有4个。每个通道相互独立地服务系统的内存请求，分别支持用于1dpc（dimm per channel）的ddr5-4400和2dpc的ddr5-4000。
1.2 ddr5 architecture
ddr5的一个主要变化是新的dimm通道结构（fig 2中channel architecture）。ddr4 dimm的总线位宽为72比特，由64比特数据位和8比特ecc位组成。ddr5的每个dimm有两个独立的子通道。两个通道中的总线位宽都为40比特：32比特的数据位和8比特的ecc位。尽管ddr4和ddr5的数据位宽相同（总共64比特），但两个独立通道可以提高内存访问效率并减少延迟。单通道单次任务只能读或写，双通道的ddr5则读写可以同时进行。
1.2 ddr5 理论带宽倚天2dpc的ddr5-4000的理论带宽为：
4000mhz *32bit / 8 *8 *2 = 128 *10^9 *2 bytes = 128gb/s *2= 256 gb/s内存等效频率（4000mhz）_ 子通道位宽（32 bit）/ 8 _ 子通道数（8）* die （2）注意gb和gib的不同：
1 gb = 1000000000 bytes (= 1000^3 b = 10^9 b)1 gib = 1073741824 bytes (= 1024^3 b = 2^30 b).2. 倚天710 ddrss pmu倚天710的ddrss为每个子通道都实现了独立的pmu，用于性能和功能调试，每个子通道的pmu包含16个通用计数器。
带宽计算公式为：
dram read bandwidth = perf_hif_rd *ddrc_width *ddrc_freq / ddrc_cycledram write bandwidth = (perf_hif_wr + perf_hif_rmw) *ddrc_width *ddrc_freq / ddrc_cycleddrc_width: units of 64 bytes3. cloud-kernel对ddrss pmu的支持#lscpuarchitecture: aarch64byte order: little endiancpu(s): 128on-line cpu(s) list: 0-127thread(s) per core: 1core(s) per socket: 128socket(s): 1numa node(s): 2...测试环境为1个socket，2个die，包含两个numa node。

1.2 ddr5 architecture
ddr5的一个主要变化是新的dimm通道结构（fig 2中channel architecture）。ddr4 dimm的总线位宽为72比特，由64比特数据位和8比特ecc位组成。ddr5的每个dimm有两个独立的子通道。两个通道中的总线位宽都为40比特：32比特的数据位和8比特的ecc位。尽管ddr4和ddr5的数据位宽相同（总共64比特），但两个独立通道可以提高内存访问效率并减少延迟。单通道单次任务只能读或写，双通道的ddr5则读写可以同时进行。
1.2 ddr5 理论带宽倚天2dpc的ddr5-4000的理论带宽为：
4000mhz *32bit / 8 *8 *2 = 128 *10^9 *2 bytes = 128gb/s *2= 256 gb/s内存等效频率（4000mhz）_ 子通道位宽（32 bit）/ 8 _ 子通道数（8）* die （2）注意gb和gib的不同：
1 gb = 1000000000 bytes (= 1000^3 b = 10^9 b)1 gib = 1073741824 bytes (= 1024^3 b = 2^30 b).2. 倚天710 ddrss pmu倚天710的ddrss为每个子通道都实现了独立的pmu，用于性能和功能调试，每个子通道的pmu包含16个通用计数器。
带宽计算公式为：
dram read bandwidth = perf_hif_rd *ddrc_width *ddrc_freq / ddrc_cycledram write bandwidth = (perf_hif_wr + perf_hif_rmw) *ddrc_width *ddrc_freq / ddrc_cycleddrc_width: units of 64 bytes3. cloud-kernel对ddrss pmu的支持#lscpuarchitecture: aarch64byte order: little endiancpu(s): 128on-line cpu(s) list: 0-127thread(s) per core: 1core(s) per socket: 128socket(s): 1numa node(s): 2...测试环境为1个socket，2个die，包含两个numa node。
