ROOT is high energy physics' software for storing and mining data in a statistically sound way, to publish results with scientific graphics. It is evolving since 25 years, now providing the storage format for more than one exabyte of data; virtually all high energy physics experiments use ROOT. With another significant increase in the amount of dat...

... and feature characteristics. Minimization is another area that can benefit greatly from the use of GPUs. The evaluation of minimizer functions can be accelerated on GPUs, especially when operating on large amounts of data. Use of analytical gradients, or automatic gradient calculation for instance with clad can provide further acceleration, see Fig. 5. Some of the algorithmic challenges remain hard, such as normalization of probability density functions when evaluating likelihood functions as seen with RooFit models; we are confident that continued R&D investment will pay off. Advances in minimizers will provide immediate benefits to RooFit. Even the side-effects from these R&D ...
