Bladebit v2.0.0-alpha2
Bladebit2 alpha 2 adds optimizations to Phase 1 and reduces the required RAM to hold all of temp2 in-cache by roughly half.
64 buckets option (-b 64) has also been added which requires rougly 11 GiB and will perform better in general.
All of temp2's data can be kept in RAM by specifying a cache of 99G and enabling alternating I/O via -a --cache 99G (assuming 64 buckets used and a standard block size of 4096).
Plotting with all temp2 in-RAM on a 128G machine
diskplot -f <farmer_public_key> -c <pool_contract_address> diskplot -a --cache 99G -t1 <temp1_path> <output_path>Use bladebit diskplot -h for more info on plotting and more information on each of the diskplot options, such as per-phase thread control.
Known Issues
- In-RAM plotting (
memplotcommand) is currently disabled. -nparameters is not supported yet and results in memory leaks and other undefined behavior.- Setting buckets to
128serializes plot files incorrectly, resulting in invalid plots (currently disabled). - Larger than usual file system block sizes may crash on Phase 1.
- Only 1 instance can be used given the same
--temp1/2directories because the file names are the same. For the time being different subdirectories can be used for multi-instance, if needed, which should not be the case.
