This is because of non-coalesced global memory access patterns of the Metropolis resampling. We devised two variations of Metropolis, namely, Metropolis-C1 and Metropolis-C2, in our previous work to ameliorate this problem. In these techniques, we ensure that the threads in a warp access the ...
The only thing I can think of at this moment is that you process two times as many values per synchronisation barrier when you have a doubly wide block. Are you sure the performance difference has to do with global memory access at all? If so, have you tried the CUDA profiler to see ...
We were unable to run MC-CNN-acrt KITTI models on the Middle- bury dataset due to the limited amount of global memory on the GPU, but we include results based on the numbers reported in [51]. It is worth noting that MC-CNN-acrt is significantly worse that MC-CNN-fst in this ...
One such subtlety lies in accessing GPU memory, where certain access patterns can lead to poor performance. Such access patterns are referred to as uncoalesced global memory accesses. This work presents a light-weight compile-time static analysis to identify such accesses in GPU programs. The ...

if that’s not possible i’d do what i can to make sure you can run (and are running) another kernel with high compute intensity (low global memory access) on the same SM at the same time to occupy all the idle times the global memory access latency is going to produce. i.e. i...
