[QE-developers] SX-Aurora TSUBASA

[Ye Luo]

Hi Naoki,
Could you put the code on gitlab or github for us to preview?
Could you say a bit more how did you "port"? Which part of QE was ported?
How did you port?
NEC aurora is an accelerator but it is not a GPU. How did you program it?
I was aware of FFT libraries for SX-Aurora. Did you use SX-Aurora via
library?

The code path to SX in FFTXLIB is not maintained for a long time I guess.
Perhaps it is time to clean/refactor that part.

Regarding compiler options, do you have a customized compiler? Or it is
gfortran or flang and you just need to just pass some -D flags?

Best,
Ye
