Please have a look @paulgessinger. I now still have a specific algorithm interface for performing the fitting "in specific ways", but also expose the template code that would allow clients to do different things as well if they so wished. I think this design could be extended to the device code as well. 🤔 |

It is a replacement for traccc::fitting_algorithm, without a templated API.
Updating all users to use traccc::host::kf_algorithm instread.
This way clients can have access to the full details of the code if they want to, while also getting algorithms that would perform fitting in one very specific way.

This is the next step in my crusade to make the reconstruction algorithms use non-templated interfaces. 😄
In this I renamed
traccc::fitting_algorithmtotraccc::host::kf_algorithm, along exactly the same lines as what I did fortraccc::host::ckf_algorithmin #722.As before, one important aspect of this is to get the memory needs of the build under control. In the current
mainbranch we use the following amounts of memory for compiling a few representative source files:seq_example.cpp: 1.4 GBcpu/throughput_st.cpp: 700 MBThis PR introduces 3 new source files, and reduces the memory needs of the previous examples like:
kf_algorithm.cpp: 320 MBkf_algorithm_teldet_cfield.cpp: 475 MBkf_algorithm_defdet_cfield.cpp: 650 MBseq_example.cpp: 1.0 GBcpu/throughput_st.cpp: 575 MBClearly this is not the end of the road yet, but I'm fairly happy with what the PR does for the build's memory usage.
