【Chia在哪交易？】XCH如何交易，操作教程！
chia-plotter（流水线多线程）
这是 chia 绘图仪的新实现，它被设计为处理管道，类似于 GPU 的工作方式，只有“核心”是普通的软件 CPU 线程。
因此，这款绘图仪能够充分利用任何存储设备的带宽，只需增加“核心”的数量，即。线程。
用法
For <poolkey> and <farmerkey> see output of `chia keys show`.
<tmpdir> needs about 220G space, it will handle about 25% of all writes. (Examples: './', '/mnt/tmp/')
<tmpdir2> needs about 110G space and ideally is a RAM drive, it will handle about 75% of all writes.
Usage:
chia_plot [OPTION...]
-n, --count arg Number of plots to create (default = 1, -1 = infinite)
-r, --threads arg Number of threads (default = 4)
-u, --buckets arg Log2 number of buckets (default = 7 (ie. 2^7 = 128))
-t, --tmpdir arg Temporary directory, needs ~220G (default = $PWD)
-2, --tmpdir2 arg Temporary directory 2, needs ~110G [RAM] (default =
<tmpdir>)
-d, --finaldir arg Final directory (default = <tmpdir>)
-p, --poolkey arg Pool Public Key (48 bytes)
-f, --farmerkey arg Farmer Public Key (48 bytes)
--help Print help
<threads>如果您有足够的内核，请确保启动，默认值为 4。根据阶段将启动更多线程，该设置只是一个乘数。
RAM 使用量取决于<threads>和<buckets>。默认情况下<buckets>和 4 个线程总共约 2GB，16 个线程总共约 6GB。
如何支持
我自己开发了这个，即使我已经用官方（慢）绘图仪填满了我所有的硬盘（~50 TiB）。
结果
在具有 256GB RAM 和 3x800GB SATA SSD RAID0的双 Xeon(R) E5-2650v2@2.60GHz R720 上，使用 110G tmpfs 用于<tmpdir2>：
Number of Threads: 16
Number of Sort Buckets: 2^7 (128)

Working Directory 2: ./ram/

如何验证
为确保绘图有效，您可以使用以下ProofOfSpace工具chiapos：
git clone https://github.com/Chia-Network/chiapos.git
cd chiapos && mkdir build && cd build && cmake .. && make -j8
./ProofOfSpace check -f plot-k32-???.plot [num_iterations]
未来的计划
我确实有一些 GPU 挖矿的历史，早在 2014 年，我就第一个开源了 XPM GPU 矿机，它的效率比 CPU 矿机高出大约 40 倍。请参阅我的其他回购。
因此，我将添加 OpenCL 支持以进一步加快绘图仪的速度，从而减轻 CPU 的大部分负载，这只是时间问题。
依赖关系
- cmake (>=3.14)
- libgmp3-dev
- libsodium-dev
安装
git submodule update --init
./make_devel.sh
二进制文件最终会在build/，您可以自由地将它们复制到其他地方（在同一台机器或类似的操作系统上）。
已知的问题
- 不使用 gcc-11 编译，使用较低版本。
- 至少需要 cmake 3.14（因为 bls-signatures）
