老师们好,我在用orca计算单点能时out文件报错说内存不足,报错内容如下:
--------------------------------
AUTOMATIC CHOICE OF INCORE LEVEL
--------------------------------
Memory available ... 256.00 MB
Memory needed for S+T ... 2113.24 MB

Error (ORCA_MDCI): not enough memory for computing triples

Calling Command: ../../orca_4_0_1/orca_mdci 1_1_pd1_9.mdciinp.tmp
[file orca_tools/qcmsg.cpp, line 432]:
.... aborting the run
然后我看以后的求助帖设置了并行运算,输入文件如下:
# avogadro generated ORCA input file
# Basic Mode
#
! F12/RI-CCSD(T) cc-pVTZ-F12 cc-pVTZ-F12-CABS
%pal nprocs 120 end

O -2.54600 0.71100 -0.68000
O -2.59900 -1.45100 -0.46800
*
但是又出现以下错误:ORCA finished by error termination in ORCA_GTOInt
用来进行计算的超算已经安装了openmpi,想请问各位老师如何解决这个问题?
