[QE-developers] SX-Aurora TSUBASA

[IWATA NAOKI(岩田 直樹)]

Dear Ye and Paolo,

Thank you very much for your quick response and your interest in SX-Aurora TSUBASA.
I will answer your questions and will provide the code to you later.

At  this moment, please look at the following site:

Best Regards,

Naoki Iwata.

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

Dear developers,

My name Naoki Iwata from NEC Corporation in Japan.
We are developing and selling a newer vector-supercomputer, SX-Aurora TSUBASA.
https://www.nec.com/en/global/solutions/hpc/

We have ported and optimized QUANTAM ESPRESSO v6.3 for SX-Aurora TSUBASA.
So we would like to ask you to implement our compile options and source code changes
for the optimization for SX-Aurora TSUBASA into the original QUANTUM ESPRESSO
makefile and source code.
I looked at the users' guide, I found the description of SX-6 and SX-8. They are old system.
So we also would like to update it to SX-Aurora TSUBASA.
What should we do for that?

Best Regards,

Naoki Iwata
