VASP計(jì)算中遇到的SIGSEGV, segmentation fault occurred錯(cuò)誤
|
|
鄙人VASP計(jì)算入門,用VASP作HSE06計(jì)算的時(shí)候,老是算著算著出錯(cuò)了,POSCAR 文件空了(對(duì)一個(gè)字符都沒有了),錯(cuò)誤提示:forrtl: severe (174): SIGSEGV, segmentation fault occurred 不懂什么意思,重新算也偶爾這樣,然而與它一塊計(jì)算的任務(wù)卻可以計(jì)算完。 這是錯(cuò)誤文件: forrtl: severe (174): SIGSEGV, segmentation fault occurred Image PC Routine Line Source vasp-openmpi-blac 000000000161D781 Unknown Unknown Unknown vasp-openmpi-blac 000000000161BED7 Unknown Unknown Unknown libmpi_usempif08. 00002AAFE2AC2D32 Unknown Unknown Unknown .o 的文件里面 For optimal performance we recommend to set | | NCORE= 4 - approx SQRT( number of cores) | | NCORE specifies how many cores store one orbital (NPAR=cpu/NCORE). | | This setting can greatly improve the performance of VASP for DFT. | | The default, NPAR=number of cores might be grossly inefficient | | on modern multi-core architectures or massively parallel machines. | | Do your own testing !!!! | | Unfortunately you need to use the default for GW and RPA calculations. | | (for HF NCORE is supported but not extensively tested yet) 求解答!感謝 |
