Question for castor mailing list

Hi everybody,

We are currently using castor to reconstruct images from GATE Simulation, the process of running castor-GATEMacToGeom and castor-GATERootToCastor is going quite well. However when running castor-recon the generation of the sensitivity image is extremely slow. A simplified version of our problem (~28672 elements) takes 16 minutes to process through this step. We would like to full simulations with nearly 10 times as many elements.

My question is, is the sensitivity image generation time purely driven by the number of elements? Is there any way to decrease the setup time, available benchmarks were done with it nearly instantaneous.

Thank you,Sveta and Peter
