Yep, I'm in contact with Jerry and Steve Wanzong down there, also
trying to figure this all out.

I am now running into some slowdown issues even on my faster machine
when decoding grib2 to gempak. I do have everything running on
a single SATA raid10 array, which may be slowing things down some.
I am hoping in the next day or two to throw in a SCSI drive to hold
the ldm queue to keep it separate I/O wise from the saved and decoded data.

Also, I'm running the dcgrib2 decoder from GEMPAK version 5.8.2. Have
there been speedups/optimizaitons in newer versions that might cut
down on the speed of GRIB2 decoding? Maybe if I compile locally with
optimizations turned on or something?

I have not yet had a chance to look at the .status files issue or to
compare my files with yours. That's hopefully this afternoon.

Ok, I definitely will. This is becoming more urgent with the potential
cutover to only GRIB2 both at NCEP and on the IDD (well, the same thing
really :)

Thanks,

Pete
