Intel Xeon 5150 (Woodcrest) 2.66 GHz, dual-processor (four CPU cores), SuperMicro X7DB8+ baseboard with Blackford chipset, 8x1024 MB DDR2 667 MHz RAM, 120 GB IDE HDD, Windows 2003 Enterprise Edition x64 SP 2 beta 1
AMD Opteron 285 2.6 GHz, Rev. E, dual processor (four CPU cores), Sun Galaxy X4100, 8x1024 MB DDR 400 ECC Registered RAM, 74GB Fujitsu 10K SAS Drive, Linux RHEL AMD64 Release 3.
Test 1, single-point direct DFT (B3LYP) energy plus gradient for medium-size system (623 basis functions). View image
Test 2, single-point semiempirical (PM3) energy plus gradient for large system (540 atoms, 2160 basis functions). View image
Test 3, single-point direct MP2 energy for medium-size system (623 basis functions, the same system as one used for Test 1). View image
Test 4, single-point two-state MCQDPT2 energy with ISA energy denominators shift for small model system. View image
Test 5, single-point direct CASSCF(12,12) for medium-size system (retinal molecule, cc-pVDZ, 565 Cartesian basis functions) using ALDET code. View image
Test 6, single-point direct CIS energy plus gradient of first excited state of medium-size system (porphyrin molecule, cc-pVTZ (aug-cc on Nitrogens), 1130 Cartesian basis functions, D2h group). View image
Tests 2 and 4 were run in multithreaded mode, other tests were run in standard parallel mode using dynamic load balancing over p2p interface. Note that test 2 does not scale well mainly due to limitations of the PC GAMESS' semiempirical code, while test 4 would scale much better for larger job. CPU or Wall clock times are given on master node in seconds.
