The gcc is 9.3.1, the mpich is 3.4.1. ??When I use openmpi 4.10 or mpich
4.0 alpha, there are more failures related to the mpi.??

Perhaps this is an issue with ARM - and such diffs are expected - as we already
have multiple alt files for some of these tests

This one is puzzling - missing fortran stdout? Perhaps compile issue on ARM?
[its a sequential example - so can't blame MPI]
Or they are all related to the optimization flags used? What configure options
were used for the build?

problems (mostly in Fortran). The function values are very different so I am
sending it to our optimization expert to take a look at it. The differences
could possibly be related to the use of real() and maybe the direct use of
floating point numbers that the compiler first treats as single and then
converts to double thus losing precision.

larger value, which keeps me from getting timeout error. The thing is I have
two machines. And I get the error code 1 in different tests on different
machines.I don??t know what is error code1. What case this? How can I fix the
failure tests.
