Dear Neks,

I was wondering if someone could help us to identify correctness tests
for Nekbone. How can we make sure that after modifying the code we still
get a valid output?
Is there anything we can use from the printed output, for instance

|cg:   ||0|  |3||.9174E+||02|
|comm time   ||0||.2370E-||01|
|cg: ||101|  |2||.9280E-||05|  |4||.3327E-||01|  |7||.6135E-||01| 
|2||.5748E-||09|
|cg:   ||0|  |4||.0900E+||02|
|comm time   ||0||.2232E-||01|
|cg: ||101|  |1||.0800E-||05|  |4||.4507E-||01|  |7||.4233E-||01| 
|3||.4828E-||10|
| |
|nelt =      ||64||, np =         ||8||, nx1 =      ||10||, elements
=       ||512|
|Tot MFlops =   ||4||.0983E+||04||, MFlops      =   ||5||.1228E+||03|
|Setup Flop =   ||8||.8960E+||08||, Solver Flop =   ||9||.6960E+||07|
|Solve Time =   ||0||.1926E+||00|
|Avg MFlops =   ||4||.0983E+||04|

Thanks for your help!
