Error: Cannot fetch non-existent child "relativeTolerance" from Node (options/iteration)

[cmakrides-hpe]

I think there's an error here with the relativeTolerance option being set only if a benchmark problem is specified.

UMT/src/teton/driver/test_driver.cc

Line 599 in a6e8898

options["iteration/relativeTolerance"] = 1e-10;

If one doesn't run a benchmark problem, i.e. the program isn't run with -b [0,1,2], the relativeTolerance isn't set and then I see an error when trying to read this option

terminate called after throwing an instance of 'conduit::Error' what(): file: /tmp/cmakrides/spack-stage/spack-stage-conduit-0.8.8-d7d3sdhauopbnumlex4gwzgcs4d2pvah/spack-src/src/libs/conduit/conduit_node.cpp line: 14197 message: Cannot fetch non-existent child "relativeTolerance" from Node(options/iteration)

The read that causes an error later on is from

UMT/src/teton/driver/test_driver.cc

Line 1362 in a6e8898

double relative_tol = options.fetch_existing("iteration/relativeTolerance").value();

There doesn't seem to be an option to the driver that allows the tolerance to be set, so in principle a default would have to be set before the test for the benchmark problem is made.
