Both the -j
and -v
flags produce errors in hadd
.
hadd
appears not to recognize the option -v
:
hadd -v 0 haddout.root haddin.root
produces
hadd Target file: 0
hadd compression setting for all output: 1
hadd Source file 1: haddout.root
Error in <TFile::TFile>: file haddout.root does not exist
Error in <TFileMerger::AddFile>: cannot open file haddout.root
hadd exiting due to error in haddout.root
-j
works fine if given at the front of the arguments but putting it at the back causes it to be interpreted both as the parallel argument and 8
as an input file:
hadd haddout.root haddin.root -j 8
produces
Parallelizing with 8 processes.
hadd Target file: haddout.root
hadd compression setting for all output: 1
Each process should handle at least 3 files for efficiency. Setting the number of processes to: 1
hadd Source file 1: 8
Error in <TFile::TFile>: file 8 does not exist
Error in <TFileMerger::AddFile>: cannot open file 8
hadd exiting due to error in 8
hadd failed at the parallel stage
I have not tested any other flags.
