Mine was not already taken into account (there is only 20 and 30). I don't know if this will solve your problem, but if your compute capability is different from 20 and 30, that may be worth a try!</p> <p><br> </p> <p>Good luck with it,</p> <p>Camille</p> <br> <br> <div style="color:rgb(0,0,0)"> <hr tabindex="-1" style="display:inline-block; width:98%"> <div id="divRplyFwdMsg" dir="ltr"><font face="Calibri, sans-serif" color="#000000" style="font-size:11pt"><b>De :</b> gate-users-bounces@lists.opengatecollaboration.org <gate-users-bounces@lists.opengatecollaboration.org> de la part de 이호연 <leehoy@kaist.ac.kr><br> <b>Envoyé :</b> vendredi 8 janvier 2016 07:37<br> <b>À :</b> gate-users@lists.opengatecollaboration.org<br> <b>Objet :</b> [Gate-users] GPU accelation problem</font> <div> </div> </div> <div> <div style="font-family:돋움; font-size:14.6667px; line-height:19px; margin-top:0px; margin-bottom:0px"> <div style="font-family:돋움; font-size:14.6667px; line-height:19px; margin-top:0px; margin-bottom:0px"> <div style="font-family:돋움; font-size:14.6667px; line-height:19px; margin-top:0px; margin-bottom:0px"> <div style="font-family:돋움; font-size:14.6667px; line-height:19px; margin-top:0px; margin-bottom:0px"> Hello,<br> <br> </div> I tried to accelate the computed tomography imaging in GATE.<br> <br> </div> But the output of the main-gpu.mac in example_GPU directory gives blank output after the phantom with GpuTransTomo actor.<br> <br> </div> I think some others have similar problem, but no one answered the questions.<br> <br> </div> <div style="font-family:돋움; font-size:14.6667px; line-height:19px; margin-top:0px; margin-bottom:0px"> Is there any one successfully obtained result image with the example code?<br> </div> <div style="font-family:돋움; font-size:14.6667px; line-height:19px; margin-top:0px; margin-bottom:0px"> Or do I need to modify some part of the code to get right result?<br> <br> </div> <div style="font-family:돋움; font-size:14.6667px; line-height:19px; margin-top:0px; margin-bottom:0px"> Thanks in advance<br> <br> </div> <p style="font-family:돋움; font-size:14.6667px; line-height:17.6px; margin-top:0px; margin-bottom:0px"> -Hoyeon</p> <p style="font-family:돋움; font-size:14.6667px; line-height:17.6px; margin-top:0px; margin-bottom:0px"> </p> <br> <table align="center" width="99%"> <tbody> <tr valign="top"> <td style="height:135px"> <p class="MsoAutoSig"><span lang="EN-US" style="font-size:10pt">---------------------------------------------------------</span></p> <p class="MsoAutoSig"><span lang="EN-US"><span style="font-size:10pt">Hoyeon Lee, </span></span><span style="font-size:10pt; line-height:1.5">Master candidate</span></p> <p class="MsoAutoSig"><span style="font-size:10pt">Medical imaging and Radiotherapeutics Lab.</span><br> <span lang="EN-US"></span></p> <p class="MsoAutoSig"><span lang="EN-US"><span style="font-size:10pt">Dept.
