[Met_help] [rt.rap.ucar.edu #82213] History for MODE - too many objects?

[John Halley Gotway via RT]

----------------------------------------------------------------
  Initial Request
----------------------------------------------------------------

I'm seeing this message on some MODE runs:
ERROR  : ModeFuzzyEngine::do_match_fcst_merge() -> too many shapes ...
increase "max_singles" to at least 534

What does it mean? Also, since there is no indication of where within the
run this occurred, I don't know what within my input files to check for the
cause.

Hello Jeff,

MET version 5.2 includes an maximum upper limit of 500 for the number
of
MODE objects.

Searching through the met-5.2 code:
   grep max_singles `find met-5.2 -name "*.h"`

That constant is defined in this file on line number 129:
   met-5.2/src/libcode/vx_shapedata/engine.h

    129 static const int max_singles = 500;

In MET version 6.0, we updated the logic of MODE to remove this
arbitrary
upper limit for the number of objects, and it instead dynamically
allocates
the required memory.

You can either switch to using MET version 6.0 or manually increase
that
upper limit and recompile.

However, when defining more that 500 objects, I suspect that your MODE
runs
are going incredibly slowly!

Hope that helps clarify.

Thanks,
John Halley Gotway

Thanks, John. That should satisfy this ticket.
