# dmrg(8)

The main DMRG++ driver

## NAME

dmrg - The main DMRG++ driver

## SYNOPSIS

**./dmrg** \[-b\] \[--threads=n\] \[--wft=yes\|no\] \[--no-finite-loops\] \[--logfile=logfile\] \[-v\] \[-h\] \[-f input-file\]

## DESCRIPTION

If no -f input-file is given, DMRG++ prints the version details and exits. Else it uses the input-file as input for the main driver.  Command line options override input file options, which in turn override defaults.

## OPTIONS

- **-b**

  Run in the background. Requires the --logfile option.

- **-f input-file**

  Use input-file as the input for the main driver. If input-file is - then read standard input.

- **-h**

  Print this message and exit.

- **--logfile=logfile**

  Do not print progress to the terminal. Close standard output and error and redirect both to logfile.

- **--no-finite-loops**

  Do not perform finite loops, that is, exit after the infinite algorithm has finished.

- **--threads=n**

  Use n pthreads. It is an error to specify this option unless the code was compiled with pthread support.

- **-v**

  Turn on verbose mode.

- **--wft=yes\|no**

  Perform or do not perform the wave-function transformation for guessing the ground state.
