+This is my NixOS configuration. I use it to manage:
+* some vps serving some websites and services (misskey, synapse), etc.
+* my laptop (Lenovo R9000P 2023), and my tablet (One Netbook One Mix 4).
+* some cluster for scientific computing (vasp, lammps, etc).
+With the following highlights:
+* All binary is compiled for specific CPU (`-march=xxx`, like that on Gentoo). 
+* All packages and configurations are managed by Nix, as much reproducible as possible.
+
+## Using overlay
+
+An overlay is provided through `outputs.overlays.default`, you could use it in your `configuration.nix` like this:
+
+```nix
+{
+  inputs.chn-nixos.url = "github:CHN-beta/nixos";
+  outputs.nixosConfigurations.my-host = inputs.nixpkgs.lib.nixosSystem
+  {
+    modules = [({pkgs, ...}: { config =
+    {
+      nixpkgs.overlays = [ inputs.chn-nixos.overlays.default ];
+      environment.systemPackages = [ pkgs.localPackages.vasp.intel ];
+    };})];
+  };
+}
+```
+
+## TODO
+
+* Write this readme file. Something have been outdate.
+* Servers in XMU should use vps9 to run proxy.
+* Allow to specify oneapiArch and nvhpcArch per package.
+* Update document. Something is outdate.

-# slurm
-
-## 基本概念
-
-队列系统换成了 slurm。这是个正经的队列系统（不像之前那样是临时手搓的），可靠性应该会好很多。
-学校的 hpc 上用的是 PBS，和这个不一样，但很多概念是相通的，例如队列、节点等（当然这里只有一个队列和一个节点）。
-这里简单记录一下如何使用。更多内容，网上随便搜一下 slurm 的教程就可以找到很多介绍，也可以看官网文档。
-
-先说明一下机器的硬件配置：CPU 有 16 个核，每个核 2 线程，也就是总共 32 个线程。
-slurm 限制 CPU 按照核（而不是线程）分配，
-  提交任务时， `sbatch` 命令中的 `cpu` 或者 `core` （它俩是同义词）都是指核的数量而不是线程数
-  （也就是说，实际运行的线程数要再乘以 2）。
-
-VASP 支持两个层面的并行，一个叫 MPI，一个叫 OpenMP，实际运行的线程数是两者的乘积。
-MPI 并行的数量就是提交任务时指定的 task 的数量，
-  OpenMP 并行的数量等于提交任务时指定的分配给每个 task 的 CPU 的数量再乘以 2，
-  也就是最终的线程数等于指定的 CPU 数量乘以 2。
-此外还有一个限制：当使用 GPU 时，MPI 并行的数量必须等于 GPU 的数量，否则 VASP 会在开头报个警告然后只用 CPU 计算（但不会报错）。
-
-## 常用命令
-
-提交一个 VASP GPU 任务的例子：
-
-```bash
-sbatch --gpus=1 --ntasks-per-gpu=1 --job-name="my great job" vasp-nvidia-6.4.0 mpirun vasp-std
-```
-
-* `--gpus=1` 指定使用一个 GPU（排到这个任务时哪个空闲就使用哪个）。
-  可以指定具体使用哪个GPU，例如 `--gpus=4090:1`。
-  可以简写为 `-G`。
-* `--ntasks-per-gpu=1` 是一定要写的。
-* `--job-name=` 指定任务的名字。可以简写为 `-J`。也可以不指定。
-* 默认情况下，一个 task 会搭配分配一个 CPU 核（两个线程），一般不用修改。如果一定要修改，用 `--cpus-per-task`。
-
-提交一个 VASP CPU 任务的例子：
-
-```bash
-sbatch --ntasks=2 --cpus-per-task=2 --job-name="my great job" vasp-gnu-6.4.0 mpirun vasp-std
-```
-
-* `--ntasks=2` 指定在 MPI 层面上并行的数量。
-  可以简写为 `-n`。
-* `--cpus-per-task=2` 指定每个 task 使用的 CPU 核的数量，OpenMP 并行的数量等于这个数再乘以 2。
-
-要列出已经提交（包括已经完成、取消、失败）的任务：
-
-```bash
-squeue -t all -l
-```
-
-取消一个任务：
-
-```bash
-# 按任务的 id 取消
-scancel 114514
-# 按任务的名字取消
-scancel -n my_great_job
-# 取消一个用户的所有任务
-scancel -u chn
-```
-
-要将自己已经提交的一个任务优先级提到最高（只是自己已经提交任务的最高，不影响别人的任务）：
-
-```bash
-scontrol top job_id
-```
-
-## sbatch 的更多参数
-
-```bash
-# 提交一个新任务，但是礼让后面的任务（推迟到指定时间再开始排队）
--begin=16:00 --begin=now+1hour
-# 指定工作目录
--chdir=/path/to/your/workdir
-# 指定备注
--comment="my great job"
-# 指定任务的 ddl，算不完就杀掉
--deadline=now+1hour
-# 标准错误输出写到别的文件里
--error=error.log
-# 将一些环境变量传递给任务（=ALL是默认行为）
--export=ALL,MY_ENV_VAR=my_value
-# 不传递现在的环境变量
--export=NONE
-# 打开一个文件作为标准输入
--input=
-# 发生一些事件（任务完成等）时发邮件
--mail-type=NONE,BEGIN,END,FAIL,REQUEUE,ALL --mail-user=chn@chn.moe
-# 要求分配内存（不会真的限制内存使用，只是在分配资源时会考虑）
--mem=20G --mem-per-cpu --mem-per-gpu
-# 输出文件是否覆盖
--open-mode={append|truncate}
-# 指定输出文件
-o, --output=<filename_pattern>
-# 不排队，直接跑（超额分配）
-s, --oversubscribe
-# 包裹一个二进制程序
--wrap=
-```
-
-# ssh
-
-ssh 就是 putty winscp 之类的工具使用的那个协议。
-
-* 地址：office.chn.moe（如果在校外，需要厦大 VPN）
-* 端口：6007
-* 用户名：自己名字的拼音首字母
-* 可以用密码登陆，也可以用证书登陆。
-
-要从本机登陆到学校 hpc 的 jykang 账户，使用下面的命令：
-
-```bash
-ssh jykang
-```
-
-# rdp
-
-就是 windows 那个远程桌面。
-
-* 地址：xmupc1.chn.moe（如果在校外，需要厦大 VPN）
-* 用户名：自己名字的拼音首字母
-* 密码和 ssh 一样。
