Disable Warning information

Hi,

For some reason, I use the remote connection to run QUESO program on a cluster. The program produces lots of text message like this:

WARNING In Algorithm<V,M>::alpha(x,y), worldRank 13, fullRank 13, subEnvironment 13, subRank 0, inter0Rank 13: y.logTarget() = -nan, x.values() = 2.27419 0.295273 2.73792 1.00725 1.32158 , y.values() = 2.25812 0.0333117 2.95789 1.05869 0.946922

My chain length is very long so the buffer becomes full and the program does not continue anymore. Is there any way to disable such message?

Thank you very much.

Hi Larry,

The reason that text is produced is because there is something wrong.

The message tells you that at this point:

2.25812 0.0333117 2.95789 1.05869 0.946922

Your posterior distribution is NaN. It's not clear to me whether this
is a QUESO bug or a user-level bug. The solution is to fix what the
problem is, not turn off the messages.

With that said, you can redirect stderr output to a file if you like:

$ my_executable 2> some_file

Hope that helps,
Damon
