Hi
without more information I will have to guess:
this is most likely NOT a libint problem. Doing a basic PBE0
calculation will cost you about 10 times more than a PBE calculation.
Now, if you didn't have enough memory (check the output) this will
be even longer. The settings of the HFX part are also crucial for performance
(screening).

Subject: [CP2K:8704] Libinit compilation
Dear Users,
I have compile libint and linked it in cp2k ssmp and psmp versions. I used ifort, icc, icpc of intel.
speed of GGA BLYP method for fullerene (C240 molecule in 30*30*30 box) is good, but when I use PBE0, a hybrid method, speed is very low.
Is it possible to compile libint with mpicc? I think libint should be very fast for HFX, but my performance is very low.
I used 6-31G** basis set for C atoms in C240.
