Description
Describe the Problem
This issue arose via METplus Discussions dtcenter/METplus#1076. @lindsayrblank reported the problem and provided data and Stat-Analysis commands to demonstrate the problem.
The void ClimoCDFInfo::set_cdf_ta(int n_bin, bool ¢er) function fails to initialize the cdf_ta array. This is called once for each "case" (i.e. OBS_SID + FCST_VAR) encountered by Stat-Analysis. And each time, that array grows by 21 elements. That's what's hogging all the memory.
Recommend fixing this in the main_v10.0 branch with a one-line fix.
Recommend fixing this in the develop branch with that same one-line fix but also add a DEBUG(3) log message for each new "case" this is created, like this:
DEBUG 3: [4756] Adding new case for key = CWBZ:TMP
Also consider re-implementing the NumArray class as an STL vector since it's default memory allocation is 1000 elements. Lindsay's jobs use less than 50 of those 1000 array elements.
Expected Behavior
The job listed below should complete in a reasonable amount of time and use MUCH less than 20GB of memory.
Environment
Describe your runtime environment:
1. Machine: Mac Laptop
2. OS: MacOS
3. Software version number(s): MET version 10.0
To Reproduce
Describe the steps to reproduce the behavior:
Use this input file to run the job below:
TMP_72hr.txt
stat_analysis -lookin TMP_72hr.txt -job aggregate_stat -line_type MPR -out_line_type CNT -out_stat TMP_72hr_output.stat -by OBS_SID,FCST_VAR -set_hdr VX_MASK OBS_SID -set_hdr DESC CASE -v 3
That job consumes well over 20GB of memory on my Mac laptop!
