Hi Xin,
Thanks a lot for providing such help to me! I may wait until the
technicians working for the university cluster finish their work, as they
agreed to help install OpenMPI 4.0.0 first (and maybe install Mvapich2 with
PGI compiler). Let me try these options first. I will let you know if

the size is 3.146MB. Actually, I also tested problems of different sizes,

guess the cluster does not use it (not exactly sure though). Actual
