Hello Osamu,
That's fantastic news! Did you just do it today? I'm curious because we have been working hard over the past two weeks to simplify the process and we're curious to hear how we've done.
The submission instructions are in ./doc/README.md. Basically, you just create a JCAHPC_Oakforest-PACS subdirectory under ./site-configs/ and copy your results into there. Also please put the input script you wrote as well as any find tools you created. Then do a pull request against the github master. Sound OK?
Thanks,
John
