MPI over GPIO and Clustering

[mixotricha]

Hi guys. I have just purchased a vim to evaluate as I am hoping to use some in a cluster that serves a nodejs application in docker. It doesn’t need to run very fast it just needs to scale in terms of cores.

I am just wondering has anyone got MPI to work with the Khadas over gpio? Is this possible?

Also has anyone written up a tutorial for combining these boards together in to a cluster?

Thanks!

Hi, Mixotricha:
I think you might intersted in:

Node.js on Khadas VIM

You can follow below step to read / write the GPIO Steps 1). You need to reconfigure the kvim_defconfig in kernel ++ CONFIG_GPIO_DEVRES=y ++ CONFIG_GPIOLIB=y ++ CONFIG_OF_GPIO=y 2). The VIM GPIO port number list GPIOH5: 176 GPIOH6: 177 GPIOH7: 178 GPIOH8: 179 GPIOH9: 180 GPIOAO6: 151 3). Write / Read the GPIO eg: config the GPIOH5 as high level output echo 176 > /sys/class/gpio/export echo out > /sys/class/gpio/gpio176/direction echo…
