 Dear Makoto,

Thank you for your kind words, it means a lot to me.

I'm not sure if I'm eligible for a full hacking lecture, but I do hack eeglab functions quite a lot, so maybe!

Since you mentioned that DipFit is one of the slowest functions on a pipeline, I thought I could share at least one of my functions, which may be useful if you are running dipfit.

Contains the function for parallel dipfit. Contribute to UgoBruzadin/Par_DipFit development by creating an account on GitHub.

If you have Parallel Computing Toolbox, you can run this function instead of the normal multifit, and it will perform the dipfit using as many cores/workers as you have available, considerably speeding up the process (by as many cores as you have, the more the merrier!) My environment has 12 cores, so this par_multifit runs ~12x faster; in my other environment I have 4 cores, so it runs par_multifit ~4 times faster than the normal multifit.

The coding isn't perfect, but it should be useful for anyone that streamlines dipfitting, or uses it on a daily basis. It may use a bit more RAM than normal, since the EEG needs to be copied and preallocated for parallel processing. It may require editing other functions to include this in your pipeline. Any suggestions or bugs, please let me know!

I have the whole order of dipfit functions running my defaults in one button on my big plugin called QuickLab, which should come out soon, but it uses defaults that may be different for different people, so the plugin still needs lots of adjustments to be independent of my own dataset.

In any case, I hope it's useful!

Dear Ugo,

Thank you for your time and detailed comment Ugo.  I'm excited to hear back
from the original author of the report.
So in your environment, CUDAICA on RTX3070 is about 12 times faster than
BINICA on Ryzen 5 5900X. My comparison of CUDAICA vs. runica is about only
4-5 times of difference--this is probably my GTX1660 is not as fast as

There are other parts in my pipeline that take longer time than others,
including CleanLine (slowest only next to ICA), clean_rawdata (RANSAC in
the electrode rejection stage, ASR), and Dipfit (gradient descent). It's
exciting that you have a solution to speed up the dipole fitting process.
Your 'library of hacks' sound so interesting--one day you should give us an
EEGLAB hacking lecture!

Please keep us posted Ugo, your input is tremendously useful for all of us
in the community!
