Capabilities Matrix
As of v4.0.1 there is limited OpenMP (multithreading) support, though not yet hybrid OpenMP/MPI.
| Method | OpenMP | MPI |
|---|---|---|
| HF energy & gradient | noa | yes |
| DFT energy & gradient | noa | yes |
| MP2 energy and gradient | yesb | yes |
| Integral transformation | no | no |
| CCMAN & CCMAN2 methods | yes | no |
| ADC methods | yes | no |
| CIS | no | no |
| TDDFT | no | no |
a Experimental code in version 4.0.1.
b To invoke an experimental OpenMP RI-MP2 code (RHF energies only), use CORR=primp2.
