Hello all, There are no file size limits in HDDM, apart from those issuing from the OS/filesystem on which the file is being written. I know there is no 2GB cutoff because I routinely exceed that limit. The design of HDDM has unlimited stream length because it is sequential access. Some people, myself included, like to write out ntuples as a side-effect of the simulation, either to monitor conditions in the simulation or do special simulation studies. If you are looking at the size of the hbook file produced in the simulation, I know that hbook has a hard 2GB filesize limit. Is that what you are running into? -Richard Jones David Lawrence wrote: > Hi Blake, > > I'm not aware of this functionality being built into HDDM as an > automatic feature, but Richard would know for sure so I'll let him > comment.
