Next patch for cudacpp-only MEs: add dummy color choice to fix 'failed to reduce to color index' #489

valassi · 2022-06-15T16:18:47Z

This is a workaround for oliviermattelaer/mg5amc_test#14

It is the first step of #402: it implements a dummy color choice (as opposed to a random color choice)

Essentially I have just added JAMP2_MULTI(0,IVEC) = NCOLOR. I have not even initialised JAMP2_MULTI(1:MAXFLOW,IVEC), it seems that addmothers.f manages this by itself somehow

… is not called (dummy random choice of color madgraph5#402) This is a WORKAROUND for "Error: failed to reduce to color indices" oliviermattelaer/mg5amc_test#14 Note: in this patch I only set JAMP2(0), while all other JAMP2(1:NCOLOR) are zero. It seems that addmothers.f already has a workaround to cover this case.

This is a followup to th eprevious PR #486.

Amongst the things that remain to be done before a first milestone (xsections ok, and events ~okish except for random color and helicity) there are these two:

compare events.lhe fortran vs cudacpp (so far only checked numbers of events)... this comparison will give differences until we fix the random choice of colors and helicities (Randomly pick one color for each event written to file (jamp2 handling) #402 Randomly pick one helicity for each event written to file #403 MadEvent final bridge interface: add multichannel, alphas, color index #404), but all the rest should already be the same
fix E-4 discrepancies fortran vs cudacpp (Physics results are different in fortran and cudacpp MEs at the ~permille level: different handling of top quark width #476)

All tests are passing, I am self merging
