v3.1.0-beta1

This pre-release includes 2 hybrid-disk plotting options:

bladebit_cuda ... cudaplot [options] <out_dir>

[OPTIONS]:
 -h, --help           : Shows this help message and exits.
 -d, --device         : Select the CUDA device index. (default=0)

 --disk-128           : Enable hybrid disk plotting for 128G system RAM.
                         Requires a --temp1 and --temp2 to be set.
 --disk-16            : Enable hybrid disk plotting for 16G system RAM.
                         Requires a --temp1 and --temp2 to be set.
 -t1, --temp1         : Temporary directory 1. Used for longer-lived, sequential writes.
 -t2, --temp2         : Temporary directory 2. Used for temporary, shorted-lived read and writes.
                         NOTE: If only one of -t1 or -t2 is specified, both will be set to the same directory

The --disk-128 mode for Linux has been available to our beta testing group for a few weeks, and Windows for just a few days. We are happy to get this into a pre-release to reach a wider audience of testers.
Some of you on Linux may have gotten to briefly try out the --disk-64 mode, which is now the --disk-16 mode. You only need 16G of RAM, some tmp space, and a CUDA GPU to make compressed plots now!
This pre-release also includes some other fixes for Windows plotting, and also a small change to Green Reaper (the plot decompression library for the harvester) that should find its way to a future Chia-Blockchain beta release.

Important

Known Issues

• --disk-16 plots on Windows is not yet well-tested, and from what we've tested internally so far, we have seen some invalid plots on one machine. We need wider spread testing, and any available core dumps, plotting logs, harvesting logs, etc. are extremely valuable to us

Please also note that from the artifacts available down below, that there are bladebit-cuda, and bladebit binaries. If you are wanting to use a GPU to make plots, be sure that you download the bladebit-cuda artifact!

What's Changed

• Fix harvester architecture selection by @wallentx in #367
• Set build-cuda.sh executable, set 3.0.1beta1 version by @wallentx in #370
• Fix CUDA plot issues on Windows by @harold-b in #381

v2.0.1-rc1

Bladebit v2.0.1-rc1

What's Changed

• Fixed C memory corruption when writing C tables
• Fixed forced warm-start for testing

Full Changelog: v2.0.0...v2.0.1-rc1

v2.0.0

Bladebit v2.0.0

NOTE: Binary artifacts have been unpublished from this release as a bug was preventing plotting after phase 1. Please obtain the new binaries from the hotfix release version 2.0.1 here, instead.

What's Changed

Disk-based plotting is now available.

Bladebit has changed to a sub-command (AKA verbs) based CLI format in order to support different plotting methods and tools.

Please see the updated Readme for more information.

To get started use ./bladebit -h for general help, ./bladebit -h diskplot for disk-based plotting information and ./bladebit -h ramplot for in-RAM plotting information.

In-RAM-based plotting remains compatible with version 1.0, except it has been moved under the ramplot command now.

Bladebit 2 also includes utilities for testing disk I/O performance and memory performance via the iotest and memtest commands, respectively. It also includes a plot validation tool under the validate command. Use the help command for more information.
