the problem I met

[Liang ZHENG]

Hi , everyone,

I met a problem when I tried running utest.

the program can not stop running the Sol_MultigridPressure3DBase with eh error after some iterations.

/opencurrent/sm13-rel/tests> ./utest -gpu 1

This isn't an error message - the [INFO] indicates it is just a status display.  The nan is because it is testing Linf convergence only, so L2 convergence isn't defined.

I would highly recommend calling 'make test' rather than running utest directly.  there are a lot of miscellaneous unit tests in the utest application that don't necessarily need to be run.  The cmake unit test (invoked via 'make test') is properly organized based on what features are enabled/disabled in your build.

Thank you ,calling make test successful.
