How to improve stability of depthmapXnet for large-scale Axial analysis (over 1M segments) in Space Syntax Toolkit? #213
Description
Hello,
Thank you very much for developing and maintaining this great tool!
I am currently using the Space Syntax Toolkit plugin in QGIS to perform Axial analysis on a very large road network dataset (over 1 million segments). However, I have been experiencing frequent crashes of depthmapXnet.
I would like to ask:
Are there any best practices or tips to improve the stability of depthmapXnet when running such large Axial analyses?
Would upgrading hardware (e.g., memory), splitting the network, or adjusting settings help?
Are there any parameters in the Space Syntax Toolkit or depthmapXnet I should pay special attention to?
Additionally, I have already upgraded to a high-performance CPU, but I noticed that the CPU utilization remains quite low when running Axial analysis. Is there a way to improve CPU usage or enable multi-core processing during the analysis?
Thank you very much for your time and help! I really appreciate your work on this amazing project.
