<div style="margin-top:0;margin-bottom:0;">Dear Ji Hye Han,</div>
<div style="margin-top:0;margin-bottom:0;"><br>
</div>
<div style="margin-top:0;margin-bottom:0;">I wish I could help you, because GPU computing is cool, but unfortunately the GPU code in Gate has not been maintained since a couple of years now and we intend to drop it completely from future releases. The original
developers have started a standalone Geant4/GPU-based simulation app called GGEMS, maybe that is a more fruitful option for you. However, it's unclear to me whether it's actually released or not.</div>

<div>Dear <span class="gmail-il">Gate</span>-developers,</div>
<div><br>
</div>
<div>I used the following code to simulate on a GPU.</div>
<div>examples -> gpumacros -> ct -> main-gpu.cpp </div>

/gate/actor/gpuactor/setGPUBufferSize 10000000 <br>
</div>

</div>
<div>Increasing setGPUBufferSize makes the data empty.</div>
<div>Is 10^7 the maximum buffer size?</div>
