OpenCAE、電子工作、R/C等、徒然なるままに

ホストレベルの低容量化

0/1のフラグを、integer=4byteからinteger(1)=1 byteへ変更 → 2.76GB → VF計算中 7.79GB
VFの精度をreal(8)からreal(4)(4byte)へ → 2.76GB(変化なし?) → VF計算中

integer(1),allocatable :: esfaced (:,:)
integer(1),allocatable :: swij (:,:)
integer(1),allocatable :: isfaced (:,:,:)

integer(1),allocatable :: isobstacle (:,:)
integer(1),allocatable :: isfinished (:,:)
real(4) :: viewfactor (n_bndfc,n_bndfc)

計算の準備に時間がかかりすぎる....。
