[Radiance-general] Resolution Mismatch in Rpict.

Thu, 27 Nov 2003 16:07:25 -0000

Hi 

We have tried a few things here to resolve this but with no luck as yet.  We
have compiled the latest HEAD distribution.  When we run rpiece it waits
about 3 minutes before it comes up with the error, but no files are created
and no other information is written to the command line.  We have just taken
a step back and run an older model on the cluster and this ran fine with
rpiece etc.  

The model .oct we are trying to run is ~300MB in size, we created it in 7
stages with the -i switch.  we do have different -r settings for each .oct
file.  Rpeice runs fine with the model on the Linux server machine.

Almost all of the cluster machines are running Linux SuSE 8.1 with a few
running Linux Red Hat 9.0.  All have the latest official release and the
server and a few others have today's HEAD distribution.

Your help is appreciated

Regards

Andrew

We are going to rebuild the .oct tonight just in case.

Hi Andrew,

This error sounds suspiciously like a communication problem between 
rpiece and rpict, since the resolution string is the first thing rpiece 
tries to read back from rpict.  I'm sure it doesn't have anything to do 
with the octree or the -x and -y options or where they appear.  Does 
rpiece die right away, or only after it's done some work?  What 
machine(s) are you running on?  Rpiece talks to its rpict process over 
a standard Unix pipe/socket, which should be reliable.  I'm quite 
puzzled by this error -- has anyone else on the list gotten this before?

-Greg
