I am a beginner in MPI.
I ran an example code using OpenMPI and it seems work.
And then I tried a parallel example in PETSc tutorials folder (ex5).
mpirun -np 4 ex5
It can do but the results are not as accurate as just running ex5.
Is that thing normal?
After that, send this job to supercomputer
this situation?

Can you give me a further explanation about why results are different
when it ran it on mutiprocessors against single processor?
Thank you!
