标题: ORCA单机并行以及内存设置疑问 [打印本页] 作者Author: zhanfei 时间: 2014-11-2 11:10 标题: ORCA单机并行以及内存设置疑问 手册是这么说的“If you run the OpenMPI version on only one computer, you do not need to provide
a machinele, and neither have to enable an rsh/ssh access, as in this case the processes will simply be forked”
我的疑问是在单机多核cpu上运行ORCA,是自动并行的,不需要设置最大允许核数像NProcShared那样?
“any problems arise, because parallelORCAdoesn't nd its executables”
那么在不报错的情况下,如何确定ORCA已经正常并行了呢?
内存设置
“one not be
surprised if the program takes more than that this size only refers to the dominant work areas. Thus, you are well
advised to provide a number that is signicantly less than your physical memory”
手册里说对某些特定模块设置的Maxcore,是对每个核心设置的,但是我没找到设置并行核心的选项,怎么设置使得充分利用内存。
为什么手册里说的设置尽量“远小于”物理内存,这样利用不是不充分吗?
谢谢大家。
