multicores in `variogramST`

[Raz316]

I use the function of variogramST. In this function, number of cores to use in parallel can be determined using cores =.

However, even though I specify the number of cores, it seems only one core is used.

I use Windows10. Is there anything to prepare to use multicores before I specify cores = in variogramST?

The futures package is used for this; please consult it's documentation.

I tried to figure out this problem with not only Windows but also Mac and Linux. However, core = did not work to use multicores. Since future package works with my PC environment, I would like you to examine if multicore process really works in gstat package.

[edzer]

It works for me.

[Raz316]

Mac, Rstudio?

[edzer]

Linux, R.

It isn't working for me either. I looked into the R source code and, for STIDF objects, the cores parameter is not being passed from variogramST to variogramST.STIDF here. I tweaked the source code by adding cores=cores at line 102 and after rebuilding the package it's now parallelizing for me.

[edzer]

Like that?

[sbashevkin]

Yes, exactly. Thank you!

[Raz316]

Thank you for the new information.

@edzer Did you change the source code in the gstat package?

From the package, it has not worked for me...

[edzer]

I changed it on GitHub, so you'd have to install it from there.

[Raz316]

Thank you. I could.
