Based on Dolence et al. 2009 ApJ. Originally downloaded from Astrophysical Code Library @ UI.
GRMONTY is parallelized using OpenMP. This version is configured to use input from harm2d.
unpack the tarball:
tar -xzvf grmonty.tgz
make (requires openmp enabled gcc):
make
set number of threads for csh and 8 threads:
setenv OMP_NUM_THREADS 8
if using bash:
export OMP_NUM_THREADS=8
run the code on the supplied harm output file:
./grmonty 5000000 dump019 4.e19
Arguments are:
- estimate of photon number (actual number is probabilistic due to scattering)
- harm dump file for model
- mass unit (few x 10^19 is appropriate for Sgr A*)
This will output spectrum to grmonty.spec which should be identical to grmonty_spec_verify.
Use python and the nmmn module:
import nmmn.sed
s=nmmn.sed.SED()
s.grmonty('grmonty.spec')
plot(s.lognu, s.ll)Old-fashioned way: Use the SM script plspec.m to plot up broad-band spectral energy distribution.
Replace harm_model.c with your own source model. Begin by modifying harm_model.c. You must supply
init_model
make_super_photon
bias_func
get_fluid_params
report_spectrum
stop_criterion
record_criterion
gcon_func
gcov_func
get_connection
in the model file.
- make it work with HARMPI
- GPU support: OpenCL
- parallelize with MPI
- add bremsstrahlung
- nonthermal electron distribution
- dynamic metrics as input
- add LICENSE
- Code and methods: Dolence et al. 2009 ApJ
- An early application: Sgr A* SED model (Moscibrodzka et al. 2009 ApJ). A more recent Sgr A* model by the same authors: Moscibrodzka et al. 2014 A&A
- More recent applications: M87 jet/RIAF SED ( Moscibrodzka et al. 2016 A&A), jet and RIAF SEDs for stellar mass black holes (O'Riordan, Pe'er & McKinney 2016 ApJ)
