Radioss怎么设置多核求解
我在HyperMesh里划分网格,设置好边界条件和工况后,直接用Radioss求解,发现CPU只占到13%最大。机器是双4核CPU,请问可以设置成多核求解吗,怎么设置? option输入栏加
-ncpu 8 谢谢你,后来问了一个他们的工作人员,也是这么告诉我的,-cpu n
我看帮助里,也是这么写的,可是我加上这个之后CPU的占用率还是那么多... Engine Keyword
/PROC - Number of Processors
Description
Number of processors.
Format
/PROC/N/M
Data
Description
N
Number of MIMD processors for this run.
M
Minimum number of MIMD processors for this run.
Default = N
Comments
1. This option has no effect in the MPP (SPMD) version: the number of processors is defined in RADIOSS Starter by domain decomposition.
2. /PROC is only applied for RADIOSS SMP parallel version (for RADIOSS SPMD parallel version, the number of processors is set in the Runname_0000.rad input deck using the /SPMD option).
3. For Flexlm type licenses:
• if the number of available licenses is greater or equal to N, the computation runs normally on N processors.
• if the number of available licenses is between N and M, the computation runs on the number of available processors.
• if the number of available licenses is lower than M, the computation does not run. 在求解时option栏输入 -CPU 4 注意CPU和4之间是有空格的 本帖最后由 417332551 于 2011-7-3 15:20 编辑
找个图片大家看看。。。。
看的更明白!!!! 按照楼上几位的方法进行设置,还是无法使用多个cpu进行计算。 使用-ncpu(或者-nt,-nt是通用,bulk和block都可以用),altair的软件因为本身的限制,调用cpu不会超过50%
