Performance Test

Note:

(1) Only the TCE CCSD(T) feature of NWChem supports GPU computing.

(2) This test case comes from the Internet. Only the last CCSD computing part uses GPUs, and other computing parts use CPUs. The computing effect is poor. Table 1 shows the comparison result.

**Table 1** Effect comparison
Test Command	Taishan 200 2280 (2 x 7260)	G5500 (2 x 6248R)
CPU	114 seconds	83.8 seconds
CPU + GPU	121 seconds	77.9 seconds
