The failure is a "floating invalid" trap at line 764 of CNSoilMatrixMod.F90 when the aux_clm test runs with matrixcnOn; the same test passes without that option. Start by reading the soil matrix code around that line and the aux_clm test definition that the author already edited to drop matrixcnOn. Done means either the root cause is identified and fixed, or the test is confirmed to pass with the intended configuration.

Descrizione

bug closed: wontfix priority: low

This issue documents a failure that may affect Paleo users (most likely), when running with matrixcnOn and the compset of this aux_clm test:
SMS_D_Ld3_PS.f09_t233.I1850Clm60BgcNoAnthroRtm.derecho_intel.clm-decStart1851_noinitial--clm-matrixcnOn.

  • The test failed consistently in PR #4234 with "floating invalid" in line 764 CNSoilMatrixMod.F90, not line 793 of the tests that pass by resubmitting a few times
  • The test's predecessor with f09_g17 passed in the baseline (ctsm5.4.063) and again while testing PR #4234
  • In RTM's testlist we use f09_f09_mt233 ONLY (instead of f09_t233), but the test fails also with that
  • In RTM's testlist we never test BgcNoAnthroRtm (so only SpNoAnthroRtm, so we didn't catch the problem in the corresponding RTM PR); that's an omission, though ok since we test BgcNoAnthroRtm in aux_clm
  • Testing RTM with matrixcnOn is unnecessary because we use the latter ONLY in SASU mode (a phase of the BGC accelerated spin-up), during which RTM preferably remains unset to conserve compute cycles
  • The test without matrixcnOn passes, so I updated this aux_clm test by removing matrixcnOn
