One consequence of the observed superlinear speedup is an improved uniprocessor algorithm by the technique of in-code parallelism.doi:10.1006/jcom.1994.1003R. ShonkwilerErik Van VleckElsevier BVJournal of Compl
Calculate the computational speedup by dividingelapsedTimes(1)by the times inelapsedTimes. Examine strong scaling by plotting the speedup against the number of workers. speedup = elapsedTimes(1) ./ elapsedTimes; plot(workers,speedup) xlabel('Number of workers') ylabel('Computational speedup') ...
Fast Simulation of Radiographic Images Using a Monte Carlo X-Ray Transport Algorithm Implemented in CUDA 50.3.2Monte Carlo Algorithm to Generate X-Ray Tracks The MC code described in this chapter[1–3]simulates a radiographic image by averaging the individual contributions to the image from a lar...
Monte Carlo Algorithm for European Call Options Valuation Taking an example, we evaluate European call options with a starting price S0 = 100 , a strike price E = 100 , risk-free rate r = 0.1 , volatility σ = 0.3 and a maturity T = 1 . The corresponding variable names we use in ...

I just finished a CUDA program to transport x rays in the GPU using a Monte Carlo algorithm. External Media Sounds very interesting indeed! I would certainly like a copy of your pre-print. I have been toying with the idea of MC radiation transport on the GPU as well, but for photon en...

Occasionally, the algorithm "swaps" values between different chains, with the probability governed by the Metropolis algorithm to preserve the stationarity of the target distribution. Possibly, these swaps can speed up the convergence of the algorithm substantially. Craiu et al. proposed an ensemble ...

Testing performed with low-enriched Uranium (LEU) and mixed-oxide (MOX) pin cell models shows a 10–20% speedup in neutron tracking rate using the improved implementation. In-line sampling and tracking of fluorescence photons was added to MC21 in 2019 [16]. The sampling algorithm uses ...
