Graphical representation of seven test molecule structures.

Structures of seven test molecules calculated by the "Direct Self-Consistent-Field" algorithm rewritten to run on a computer's graphical processing unit (GPU). The numbers indicate how much faster the GPU-ran algorithm calculates the structure of molecules in comparison to a molecular design program called GAMESS running on a computer's central processing unit. Carbon atoms are aqua, nitrogen atoms are blue, oxygen atoms are red and hydrogen atoms are white. In the image above, C60 is made of 60 carbon atoms and commonly referred to as a "buckyball," valinomycin transports potassium ions in biological systems, taxol is a chemotherapy drug, and CLN025 is a recently reported artificial protein.

Graphical representation of seven test molecules and 3D electron orbitals.

Graphical representation of seven test molecules and 3D electron orbitals. The molecular structures were calculated by the "Direct Self-Consistent-Field" algorithm rewritten to run on a computer's graphical processing unit. Positive and negative regions of the electron orbitals are colored blue and orange, respectively. Carbon atoms are aqua, nitrogen atoms are blue, oxygen atoms are red and hydrogen atoms are white.
