Crashes over 10M rays #27

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. Set the ray count to 10M or more (threshold depends on the geometry (photon 
impacts count ?). With your EuroDish example threshold seem higher, it crashed 
at 50M. With my joined  geometry, limit is between 5 and 10 M.)
2. Launch ray tracing

What is the expected output? What do you see instead?
-> Tonatiuh crashes
-> It also crashes by doing several smaller ray casting and increasing the 
photon maps beyond such rays number.
I'm looking for "high" ray counts to get better resolution on my flux maps by 
having higher resolution binning. I process photon maps in Java and draws them 
with R.

What version of the product are you using? On what operating system?
Version 1.01 under MacOS X 10.5 and 10.6 and Windows 7 64 bits.

Please provide any additional information below.
Tests on two computers & 3 OS: 
- MacPro 2x Xeon 5150 8 G RAM MacOS 10.5
- MacBook Pro Core i7 620M 4 G RAM MacOS 10.6
- MacBook Pro Core i7 620M 4 G RAM Windows 7 64 bits

For every new Tonatiuh version, we try to reduce the memory limitation. If the 
memory is a problem for you, you can define a script to run your model several 
times and save the results for each ray tracing process.
