<div dir="ltr">Hoi,<div><br></div><div>I may need some hint about how the stream division works in rtkfdk.</div><div>I noticed that the StreamingImageFilter from ITK is used but I cannot figure out quickly how the division has been performed.</div>
<div>I did some test with reconstructing 400 1500x1200 projections into a 640xNx640 volume (the pixel and voxel size are comparable).</div><div>The reconstructions were executed by rtkfdk with CUDA.</div><div>When I leave the origin of the volume at the center by default, I can reconstruct up to N=200 slices with --divisions=1 due to the limitation of the graphic memory. Then when I increase the number of divisions to 2, I can only reconstruct up to 215 slices; and with divisions to 3 only up to 219 slices. Does anyone have an idea why it scales like this?</div>
<div>Thanks in advance.</div><div><br></div><div>Best regards,<br></div><div>Chao</div></div>
