Failed to evaluate Schwarz integrals

Dear QChem community,

I am having problems using the ANO-RCC basis set with MnH molecule taken from https://www.basissetexchange.org/, since there are no native ANO basis sets available directly in its standard basis set library. I use it in a simple HF calculation:

"
$molecule
0 7
Mn1
H2 Mn1 1.710
$end

$rem
JOBTYPE sp
METHOD HF
BASIS GEN
PURECART 1111
$end
"

I obtain that this error before the SCF calculation starts:
"
Distance Matrix (Angstroms)
Mn( 1)
H ( 2) 1.710000

ERROR in qints omp thread 1/1: std::bad_alloc
ERROR in qints omp thread 1/1: std::bad_alloc

Q-Chem fatal error occurred in module libqints/qchem/aoints_job002.C, line 98:

Failed to evaluate Schwarz integrals.
Set SCHWARZ_INTS = -1 to disable Schwarz screening.
"

I have not included the basis set because its lenght. Do you know what is happening here? Thank you very much in advance for your help.

Please provide a complete input file. Use the </> button (preformatted text) so that the GUI doesn’t eat the special characters.

Update: this calculation ran fine with Q-Chem v6.2.1.

I am currently working with this version of QChem and it does not work.

Since Kaushik says the job runs with Q-Chem v. 6.2.1, I suspect this is a limitation of the new integrals code that existed in earlier versions of Q-Chem. What version are you running?

A few suggestions:
(1) Did you try doing what the output file suggested, namely, setting SCHWARZ_INTS = -1 in $rem ?

(2) My attempt to run your input with Q-Chem v. 6.2.1 crashed with a message that the integrals code needs 175157 MB of MEM_TOTAL, so this is clearly a very high memory requirement (due to the high angular momenta and contraction lengths).

(3) Finally, you can try running the job with the old integrals code by setting USE_LIBQINTS = FALSE in $rem.

Update: this job does appear to run with the old integrals code, suggestion (3).

To add to Prof. Herbert’s recommendations, it is also unclear by your comment whether you got the same error with v6.2.1 as with v6.0.1 or an error related to the memory requirement. The calculation should run fine with v6.2.1 if you set an adequate MEM_TOTAL, as I had explained earlier in the support email.
