Can I use multithreaded computing？

[gqf520]

Hello, how can I save time by performing multi-threaded calculation.

Of course! In fact, I’ve already set up multithreading in the script:

WGCNA::allowWGCNAThreads(nThreads = 5)

You can modify the number of threads in the script before launching the app.

If the issue you’re experiencing is related to long wait times during the sft test step or the module construction step, this is likely due to the computation of the TOM matrix. I suspect the problem arises because you are still using R's built-in BLAS library. The built-in BLAS in R has low efficiency for matrix computations. I recommend replacing it with OpenBLAS to improve performance.

You can refer to the following link for guidance on switching to OpenBLAS to accelerate matrix computations:
