CentOS7 單節點和多節點 HPL測試

前置工作:安裝OpenBLAS; 安裝Mpich

  • 官網下載壓縮包到/opt目錄

    cd /opt && wget https://www.netlib.org/benchmark/hpl/hpl-2.3.tar.gz
    
  • 解壓到 /opt 目錄

    tar -xzf hpl-2.3.tar.gz
    
  • 複製Make.Linux_PII_CBLAS並重命名

    cd /opt/hpl-2.3 && cp setup/Make.Linux_PII_CBLAS Make.Linux
    
  • 編輯Make.Linux

    vim Make.Linux
    

    修改如下內容:

    ARCH = Linux
    
    TOPdir = /opt/hpl-2.3  # hpl安裝目錄
    
    MPdir = /opt/mpich     # mpich安裝目錄
    MPlib = $(MPdir)/lib/libmpi.a # mpi連結庫
    
    LAdir = /opt/OpenBLAS # openblas安裝目錄
    LAlib = $(LAdir)/lib/libopenblas.a  # openblas連結庫
    
    CC = /opt/mpich/bin/mpicc # compiler
    CCFLAGS = $(HPL_DEFS) -fomit-frame-pointer -O3 -funroll-loops -pthread
    
    LINKER = /opt/mpich/bin/mpif77 # linker
    

    以上路徑根據個人安裝時的目錄修改

  • 構建hpl

    make arch=Linux
    

    若build成功,則會在/opt/hpl-2.3/bin/Linux目錄下生成HPL.dat和xhpl檔案

  • 測試hpl

    cd /opt/hpl-2.3/bin/Linux
    
    1. 單節點測試

      mpiexec -np 4 ./xhpl
      
    2. 多節點測試

      編輯節點檔案,輸入節點主機名或IP地址

      vim nodes
      

      eg:

      修改HPL.dat

      HPLinpack benchmark input file
      Innovative Computing Laboratory, University of Tennessee
      HPL.out      output file name (if any)
      6            device out (6=stdout,7=stderr,file)
      1            # of problems sizes (N)
      1200         Ns
      1            # of NBs
      232          NBs
      0            PMAP process mapping (0=Row-,1=Column-major)
      1            # of process grids (P x Q)
      1            Ps
      4            Qs
      16.0         threshold
      1            # of panel fact
      0            PFACTs (0=left, 1=Crout, 2=Right)
      1            # of recursive stopping criterium
      2            NBMINs (>= 1)
      1            # of panels in recursion
      2            NDIVs
      1            # of recursive panel fact.
      0            RFACTs (0=left, 1=Crout, 2=Right)
      1            # of broadcast
      0            BCASTs (0=1rg,1=1rM,2=2rg,3=2rM,4=Lng,5=LnM)
      1            # of lookahead depth
      1            DEPTHs (>=0)
      2            SWAP (0=bin-exch,1=long,2=mix)
      64           swapping threshold
      0            L1 in (0=transposed,1=no-transposed) form
      0            U  in (0=transposed,1=no-transposed) form
      1            Equilibration (0=no,1=yes)
      8            memory alignment in double (> 0)
      

      執行hpl

      mpiexec -np 4 -machinefile ./nodes ./xhpl
      
    3. HPL.dat配置項解釋
