Crypto - Chia - CLI - Plot - Plot with a ramdisk

Using a Ramdisk can speed up plotting.

NOTE: This requires at least 256GB of RAM available.


Create a Ramdisk

mkdir /mnt/ramdisk
mount -t tmpfs -o rw,size=240G tmpfs /mnt/ramdisk

NOTE: This mounts a ramdisk with 240GB under the path /mnt/ramdisk.

  • -t tmpfs:
    • tmpfs only uses memory when you it contains files.
    • When it is empty, it will take almost no space in RAM.

See: https://manpages.debian.org/buster/initscripts/tmpfs.5.en.html


Verify the Ramdisk

Verify that the RAMDISK has been created.

df -h

Mount the Ramdisk automatically on system boot

Edit /etc/fstab, and add the following line to the the end of the file.

/etc/fstab
tmpfs  /mnt/ramdisk  tmpfs  rw,size=240G  0   0

Create the Chia Plot

Creates a new plot.

chia plots create -k 32 -r 6 -n 1 -t /mnt/ramdisk -2 /home/peter-chia-temp -d /home/peter-chia

NOTE:

  • -k32: Creates a k32 plot.
  • -r 6: Specifies six processor cores.
    • These cores are used primarily in phase 1 and 2.
  • -n 1: Creates exactly one plot.
  • -t /mnt/ramdisk: Specifies the temporary directory.
  • -2 /home/peter-chia-temp: Specifies the second temporary directory (Optional).
    • Depending on the size of the ramdisk, this optionn might be needed otherwise there could be insufficient memory to write the plot file at the end.
  • -d /home/peter/chia: Specifies the final directory for the plot.
