[英]CDO select variable in parallel
I want to select/split a specific variable TT
from a big NetCDF file using the CDO
library/package in parallel to speed up the process.我想并行使用
CDO
库/包从大型 NetCDF 文件中选择/拆分特定变量TT
以加快进程。
I used the following:我使用了以下内容:
cdo -P 8 select,name=TT infile.nc outfile_TT.nc
but got the following error:但出现以下错误:
-bash: cdo -P: command not found
I have tried also -selname
and -select
as operators but it gives me the same error.我也尝试过
-selname
和-select
作为运算符,但它给了我同样的错误。
It only works when I run it in serial (ie, remove -P 8
) as follows:它仅在我以串行方式运行(即删除
-P 8
)时才有效,如下所示:
cdo select,name=TT infile.nc outfile_TT.nc
Is it possible to run this in parallel using CDO
?是否可以使用
CDO
并行运行?
According to the CDO documentation ( Appendix B - Parallelized operators ) parallel processing is not supported for select
operator.根据 CDO 文档( 附录 B - 并行化运算符),
select
运算符不支持并行处理。
