Hello Kumagai-san,

I'm now trying to reserve the machine with big memory, but I'm not
accurately sure when I can use the machine; expecting within this
month? In advance, I want to make sure what I measure in this
benchmark in more detail.

I'm going to collect at least what you showed in your benchmark: RSS
size for no option, -cd31 and -Ed31. Is there another to collect?

Thanks.
HATAYAMA, Daisuke
