Configuring the sudo Permission

During the HPC cluster consistency check, if you run mpirun as a common user and want to collect data that can only be collected by privileged users, configure the sudo permission for the common user.

1. Go to the corresponding directory.

   cd /etc/sudoers.d

2. Create a sudoers file.

   Name the sudoers file as required, for example, mpi_sudoers.

   vim mpi_sudoers

3. Edit the sudoers file.

   Add the following configuration information to the file. mpi2test is the user configured for the current server.

   1 mpi2test    ALL=(root)      NOPASSWD:/usr/sbin/dmidecode -t bios
   2 mpi2test    ALL=(root)      NOPASSWD:/usr/sbin/lshw -class memory -json
   3 mpi2test    ALL=(root)      NOPASSWD:/usr/sbin/dmidecode -t memory
   4 mpi2test    ALL=(root)      NOPASSWD:/usr/sbin/lshw -class network -json
   5 mpi2test    ALL=(root)      NOPASSWD:/usr/sbin/cma_roce_tos
   6 mpi2test    ALL=(root)      NOPASSWD:/usr/sbin/lshw -class bridge -class storage -class disk -json

   Press Esc and run :wq! to save the settings and exit.

4. (Optional) Repeat the preceding steps on servers where you, as a common user, want to collect data that can only be collected by privileged users.
