please do not print debug output by default

[jeffhammond]

I have not yet found where the option to disable the following debug printout, but in any case it should not be on by default, particularly since the first part is O(n).

Please tell me what option I used to disable this, since I assume that already exists.

Ah, right. add --v=0 to the command line, or set GLOG_v=0 in the environment. I'll change the default in the code.

[jeffhammond]

Thanks!

[jeffhammond]

That environment variable appears to have no effect.

[jrhammon@esgmonster github-official]$ export GLOG_v=0
[jrhammon@esgmonster github-official]$ mpirun -n 36 GRAPPA/Transpose/transpose 10 $((32*36)) 32

I cannot pass --v=0 as an argument to mpirun or GRAPPA/Transpose/transpose, because it is not a valid argument for either. Do I misunderstand how to use this option?

[nelsonje]

Try

mpirun -n 36 GRAPPA/Transpose/transpose --v=0 -- 10 $((32*36)) 32

[jeffhammond]

That works.
