cscs-ci run checking if the workaround works also in the CI. In case, I will document more the case and use it to investigate deeper the problem. |

This PR improves computeTFactor computation by parallelising the computation that previously was serialised because of the reduction over a single tile.
The algorithm implementation has been split in two variants:
Backend::MCnow has thebulk-based implementationBackend::GPUstill use the previous version of the codeThis required a couple of changes to the interface structure of the algorithm, and I took the chance to fix also some problem with the documentation.
Note: Look at first three commits to see the main implementation change in a more "isolated" way from the rest.
