火神

陌路者跳海自杀,然并无水花,浅滩似沼泽,

但凡前往营救者,皆吞噬。

人愈多,洞愈大。

竟平地起风,似龙卷,毁万物。

唯寻驾驭火种之垂髫,方可破。

平地之下

尸体之上建废墟

废墟之上造城市

纵现尸首 视之若无

腐烂之味 闻之又散

坍塌 暴露 风化

尸体之下藏宫殿

宫殿之下藏尸体

层层堆叠 无底之洞

洞中

时而鲜花盛开

时而鲜血淋漓

五味杂陈 皆由味觉

时空之曲

时空坍塌之际

畅游于漩涡

见世间所不得见

一举一动

若译为音符

则成循环之曲

其调未知

似为古谣

维度

若时间算一维度

则在该维度

世人皆可

穿梭自由

且不为外知

不为己知

Installing libraries and automating WRF-Chem

Backgroud

NETCDF version (netcdf/4.5.0/02-CF-17-par) on TH-2 seems something wrong. This results in error when NETCDF4 of WRF-Chem enabled (NETCDF4=1). So, I decide to compile NETCDF on my own.

Prerequisite

According to NetCDF’s instruction , we need zlib and hdf5 first. For zlib, I use the version zlib/1.2.11-icc17 originally compiled by TH-2.

HDF5

The newest version is 1.10.4.

$ ./configure --prefix=/HOME/nuist_chenq_2/WORKSPACE/xin/software/hdf5-1.10.4 --enable-fortran --enable-static-exec

But, I got this error:

Speedup WRF-Chem

Background

This is my partial namelist of WRF-Chem:

&time_control
run_days = 147,
&domains
time_step = 72,
time_step_fract_num = 0,
time_step_fract_den = 1,
max_dom = 1,
e_we = 430,
e_sn = 345,
e_vert = 40,
dx = 12000,
dy = 12000,
p_top_requested = 10000,

I used 384 cores to run it and I found the speed of calculation and writing is ~5.45 seconds/step, ~54.5 s/wrfout_file and ~210 s/wrfrst_file. The terrible one is the speed of I/O tasks.
