Histogram showing the speed of the two peak-finder algorithms, RPF (blue) and PF8 (orange). Two hundred thousand diffraction images were selected randomly from the EuXFEL commissioning data set and both RPF and PF8 were used to classify images as `hits'. The speed with which these algorithms carried out this task is demonstrated by plotting the number of diffraction patterns versus the processing time per frame. The histogram is generated using a single node with 80 cores (INTEL, E5-2698 v4 @ 2.20 GHz, memory 512 GB) from the UPEX partition in the Maxwell computing cluster. |
