I am currently trying to perform a model from model builder over 600,000 feature classes in arcgis 10.2 (perhaps 10.2.1 or 10.2.2)
In this model I use these tools (several times): viewshed analysis, raster calculator, extract by attributes, extract by mask, buffer, and erase.
To speed up the calculation, I'd like to use parallel processing. But because of urgent deadlines I cannot afford to learn about the correct way to perform it.
I've seen that not all tools can be used in the parallel processing environment and honestly, I don't have the time to check all the tools I use or find alternatives and of course learn to debug the final model with parallelisation in it.
Instead, I was told to split the work and run it in several arcgis windows opened at a same time. This works actually pretty well.
But after a time, if I check the Windows Task Manager, the memory use will increase a lot and at the same time the calculation speed will decrease.
Eventually the model crash and I have to start over where it ended.
My question is: does anyone no where precisely this comes from? Or more importantly, how to solve the problem.
I run the models from arctoolbox, not from model builder, so intermediate data should be erased at each run of the loop.
Thanks in advance for the help!
