<div dir="ltr">Dear Gate users,<div><br></div><div>I have compiled the latest develop version of Gate with Geant4-10.05.p01 under <span class="" id=":c7.28" tabindex="-1" style="">macOS</span> Mojave. Previously using <span class="" id=":c7.29" tabindex="-1" style="">vGate</span> on the same <span class="" id=":c7.30" tabindex="-1" style="">MacBook</span>, I was hoping for decreased simulation time after removing the virtual machine intermediary. However, tests shows nearly no differences - <span class="" id=":c7.31" tabindex="-1" style="">vGate</span> is even a bit faster - regardless of the simulation duration (minutes / dozens of hours). </div><div><br></div><div>Therefore, I would like to know if anyone had similar experiences, and if this kind of results are to be expected. Also, is there any way of increasing the performances of Gate on <span class="" id=":c7.32" tabindex="-1" style="">macOS</span> by optimizing the compilation parameters?</div><div><br></div><div>You can find enclosed a simple test file which has been adapted from <span class="" id=":c7.33" tabindex="-1" style="">GateContrib</span> Cylindrical PET example (<a href="https://github.com/OpenGATE/GateContrib/tree/master/imaging/PET" target="_blank">https://<span class="" id=":c7.34" tabindex="-1" style="">github</span>.com/<span class="" id=":c7.35" tabindex="-1" style="">OpenGATE</span>/<span class="" id=":c7.36" tabindex="-1" style="">GateContrib</span>/tree/master/imaging/PET</a>). The resulting simulation time is 8min44s when using <span class="" id=":c7.37" tabindex="-1" style="">vGate</span> and 8min50sec when using Gate under <span class="" id=":c7.38" tabindex="-1" style="">macOS</span>.</div><div><br></div><div>Best regards,</div><div>Antoine</div></div>
