The tutorial is a bit in a sorry state since it did not yet follow the most
recent QCDNUM developments.
When all the dust has settled, I will give it a new shine.
In one of the appendices of the QCDNUM-17-01/xx write-up you can find a tutorial on how to use the toolbox to build code to evolve unpolarised pdfs at LO in the FFNS and the VFNS.
Also included are sections on how to write a fast interpolation routine, how to calculate the F2 structure function and, finally, how to make the code robust and user-friendly so that you can release it as a package that can safely be used by somebody else (these last two sections are still missing).
In the subdirectory testjobs of the QCDNUM distribution you can find example jobs for each step in the development of the evolution program.
| Toolbox00.f | Starting point with a basic set-up of QCDNUM. |
| Toolbox01.f | Partition the local workspace into sets of tables. Automatically maintain up-to-date weight tables on disk. At this point the weight tables are still empty. |
| Toolbox02.f | Fill the weight tables of the unpolarised splitting functions. |
| Toolbox03.f | Fill the alfa-s table and keep it up-to-date. |
| Toolbox04.f | Singlet/gluon and non-singlet evolution of unpolarised pdfs. |
| Toolbox05.f | Fully handle evolution in the FFNS and VFNS. |
| Toolbox06.f | Transform an arbitrary set of input densities into a set of singlet/non-singlet starting pdfs. |
| Toolbox07.f | Fast interpolation of the evolved pdfs in terms of gluon, quark and antiquark densities. |
