--- Comment #9 from Tom de Vries <vries at gcc dot gnu.org> --- (In reply to Tobias Burnus from comment #8) > I am wondering whether it has something to do with shfl now requiring .sync, > especially for sm_70. (Non-sync version was deprecated in ISA 6.0 and for > sm_70 removed in ISA 6.4.) > Cross ref: PR96005. Could be. Posted a tentative patch at that PR, you could try that out. Still, only root cause analysis can get us ... the root cause. I can try to do that if you provide me with access to one of the volta machines. Otherwise, can you or somebody else with access to these machines do that? I could coach the effort a bit, if necessary.
