+Setting up OpenCL on RK3588 using libmali
+============================
+## [Installing OpenCL](https://clehaxze.tw/gemlog/2023/06-17-setting-up-opencl-on-rk3588-using-libmali.gmi#installing-opencl)
+
+Assuming you have successfully booted into your system. You need to download the ARM Mali GPU blob from rockchip's repository. And put it into `/usr/lib/`. As well as the firmware for the GPU if not already installed.
+
+```bash
+cd /usr/lib sudo wget https://github.com/JeffyCN/mirrors/raw/libmali/lib/aarch64-linux-gnu/libmali-valhall-g610-g6p0-x11-wayland-gbm.so cd /lib/firmware sudo wget https://github.com/JeffyCN/mirrors/raw/libmali/firmware/g610/mali_csffw.bin
+```
+
+Now we need the OpenCL ICD loader. The one in apt will suffice. Then, since we manually downloaded the Mali GPU blob, we need to add it to the OpenCL ICD config file.
+
+```bash
+sudo apt install mesa-opencl-icd clinfo sudo mkdir -p /etc/OpenCL/vendors echo "/usr/lib/libmali-valhall-g610-g6p0-x11-wayland-gbm.so" | sudo tee /etc/OpenCL/vendors/mali.icd
+```
+
+Finally, we need to statisify the dependencies of the Mali OpenCL.
+
+```bash
+sudo apt install libxcb-dri2-0 libxcb-dri3-0 libwayland-client0 libwayland-server0 libx11-xcb1
+```
+
+Now you can run `clinfo` to see if OpenCL is working.
+
+```bash

+Memory bandwideth on the Orange Pi 5 Plus seems to be slower then on the Mixtile Blade 3. Howerver, driver improvements seem to have increased the compute slightly. Even fixed a few cases on suprising low throughput. You can find the clpeak benchmark results of Mixtile Blade 3 in my older post.

+
+FluidX3D is a fluid dynamics simulation software. This benchmark takes a long time to run on the Orange Pi 5 Plus. While running the SoC maintains around a temperature around 44°C with my baseline cooling setup. I bet it'll thermal throttle without a fan. And I can do better if I get a small fan and blow air directly into the heatsink.
+
+-   A 50mm aluminum passive heatsink
+-   A circulation fan blowing air over the heatsink
+-   Ambient temperature of 25°C

+
+#### Powering On All Nodes at Startup
+
+By default, the Turing Pi 2 doesn't power on any nodes at startup. While this can be beneficial in certain scenarios, it might not be ideal in situations like recovering from a power outage. To alter this default behavior, a small startup script can be added. Create the file S99zallnodeson.sh in the /etc/init.d directory with the following content:
+
+```bash
+ssh root@192.168.1.10
+vi /etc/init.d/S99zallnodeson.sh
+```
+
+```sh
+#!/bin/sh  
+while ! netstat -tuln | grep LISTEN | grep ':80 '; do sleep 1; done
+```
+
+##### Turn on all nodes
+
+`tpi -p on` The name of the file must follow alphabetically the name S99hello.sh because the BMC server starts in the S99hello.sh.
