Problem during Support Vector Regression analysis

Dear all, I'm running SUpport Vector Regression analysis on matlab2020b on win10 64bit. The script and all the analysis works very well on my old quadcore i7, while on my new 12 cores i7 (same data, matlab version and win) doesn't work and stop during permutation test without any error messagge, just stopped permutations. Any coomments are more than welcome. Thank you very much.

Hi LF,

It seems that you are experiencing an issue when running Support Vector Regression analysis on your new 12-core i7 machine in MATLAB 2020b on Windows 10 64-bit. The analysis works fine on your old quad-core i7 machine, but on the new machine, it stops during the permutation test without any error message.

Here are a few suggestions to help troubleshoot the issue:

1. Check for resource limitations: Verify that your new machine has enough resources (RAM, disk space) to handle the analysis. The permutation test may require more memory or processing power than your old machine, so it's worth checking if there are any resource limitations causing the analysis to stop.
2. Check for parallel processing issues: Since you mentioned your new machine has 12 cores, it's possible that the issue is related to parallel processing. Check if the permutation test is utilizing all the available cores correctly. You can try adjusting the number of workers or disabling parallel processing temporarily to see if it resolves the problem.
3. Review the code and data: Double-check your code and data to ensure there are no issues specific to your new machine's environment. Make sure all paths and dependencies are correctly set up, and the data is in the expected format.
4. If the analysis stops consistently at a particular point during the permutation test, try dividing the test into smaller parts. This can help identify if there is a specific issue with a subset of the data or a particular step in the analysis.

If the issue persists after trying these steps, it might be helpful to contact MathWorks Technical Support and provide more specific details about your analysis, including the relevant code snippet and any additional information you can provide.

Hope it helps,
