SNANA hangs at initialization stage for 1+ hr #504

marlena6 commented 3 years ago

I'm running SNANA with the input file SIMGEN_MASTER_IDEAL_zALL_GHOSTLIB_SNII.INPUT in $SNANA_LSST_ROOT/PLASTICC/survey_config. It starts running but hangs after:

########################################################
     INIT_SNVAR: Init variables.
  ########################################################
   Allocate 12.50 MB for CIDMASK array (to check duplicates)

I cancelled the jobs after about 1 hr. Logs can be seen in SIMLOGS_ML_IDEAL_zALL_TEST_GHOSTLIB_SNII

Please try trimming the number of HOSTLIB variables down to 1 or 2 dozen: mags, Sersic, wgtmap variables plus a few others. Since the entire HOSTLIB is read into memory, it was never intended to be a complete library of all HOST parameters.

This was due to array bound overflow that wasn't caught, and likely corrupted some part of memory. Array overflow is now trapped and abort gives error message.
