TraceR can be used for predicting network performance and\nunderstanding network behavior by simulating messaging in High Performance\nComputing applications on interconnection networks.\n\n\n### Build\n\nTraceR depends on [CODES](https://xgitlab.cels.anl.gov/codes/codes) and [ROSS](https://github.com/ROSS-org/ROSS). There are several ways to build TraceR:\n\n1. Use [spack](https://github.com/spack/spack) to build TraceR and its dependencies:\n```\n    spack install tracer\n```\n\n2. Build TraceR and its dependencies manually:\n\n* Download and install ROSS and CODES. Set the appropriate paths: ROSS_DIR, and\n  CODES_DIR in tracer/Makefile.common.\n* Pick between the two trace formats supported by TraceR: OTF2 or BigSim, and\n  accordingly build the OTF2 or Charm++ library. If using OTF2 traces\n  (default), set SELECT_TRACE = -DTRACER_OTF_TRACES=1, and ensure that\n  otf2-config is in your PATH. If using BigSim traces, set SELECT_TRACE =\n  -DTRACER_BIGSIM_TRACES=1, and set CHARMPATH to the Charm++ installation in\n  tracer/Makefile.common.\n* Set the ARCH variable in tracer/Makefile.common or alternatively set the CXX\n  and ARCH_FLAGS variables. Then type:\n```\ncd tracer\nmake\n```\n\nMore detailed build instructions are available on TraceR's [documentation](https://tracer-codes.readthedocs.io/en/master/index.html#document-install) pages.\n\nRefer to TraceR's [User Guide](https://tracer-codes.readthedocs.io/en/master/userguide.html) for details on how to do network simulations using TraceR.\n\n\n###  Citing TraceR\n\nAny published work that utilizes TraceR should cite the following paper:\n\nNikhil Jain, Abhinav Bhatele, Samuel T.
