[mvapich-discuss] mvapich2 error/romio/PMB-IO

[TaoJinZhong]

Hello all:    I configure,build and install mvapich2-1.0 on the Linux cluster¡£The system configurations are listed in the following:      2.6.9-42.ELsmp/4*Intel(R) Xeon(R) CPU/16G Memory/Lustre filesystem    The hca driver is based on OFED-1.1.1.I use make.mvapich2.ofa to install the mvapich2-1.0,and modify the configure line to include "--with-romio --with-file-sysmtem=nfs+ufs" to support ROMIO.    When i run the PMB-IO(Pallas MPI Benchmarks 2.2.1),the erros are following:_________ [root at cn001 SRC]# /home/mvapich2-io/bin/mpiexec -n 4 ./PMB-IO   #----------------------------------------------------------------------------- # Benchmarking P_IWrite_Indv  # ( #processes = 1 )  # ( 3 additional processes waiting in MPI_Barrier) #----------------------------------------------------------------------------- # #    MODE: AGGREGATE  #       #bytes #repetitions t_ovrl[usec] t_pure[usec]  t_CPU[usec]   overlap[%]            0           50     94918.84        36.32     89349.03        
  0.00   rank 0 in job 39  cn001_38658   caused collective abort of all ranks   exit status of rank 0: killed by signal 9 ---------    1.Because the ROMIO module don't support the Lustre Filesystem,i want use the UFS(romio) to instead.The execution PMB-IO is in the lustre filesystem.And the partial results are also seem illogical,for example:--------  #----------------------------------------------------------------------------- # Benchmarking P_Write_Indv  # ( #processes = 4 )  #----------------------------------------------------------------------------- # #    MODE: AGGREGATE   #       #bytes #repetitions  t_min[usec]  t_max[usec]  t_avg[usec]   Mbytes/sec            0           50        22.30        25.66        23.61         0.00            1           50         1.66         8.96         3.67         0.11            2           50         1.44         8.18         3.28         0.23            4           50         1.56         8.66         3.47         0.44
