Temp Drive Plotter Phase Settings
Because Chia Phase 1 utilizes more memory and cpu (thread) resources AND is the only multi-threaded stage (after phase 1, the jobs are single threaded). These phase settings can help fine tune your chia plotting process beyond setting a stagger or limit on number of concurrent jobs.
There are 3 parameters that will help you achieve this. But before learning those, take a look at the table below, to learn all the phases and steps of the chia plotting process:
| Phase | Step | % Progress |
|---|---|---|
| 1 | 1 | 1% |
| 1 | 2 | 6% |
| 1 | 3 | 12% |
| 1 | 4 | 20% |
| 1 | 5 | 28% |
| 1 | 6 | 36% |
| 1 | 7 | 42% |
| - | - | - |
| 2 | 1 | 43% |
| 2 | 2 | 48% |
| 2 | 3 | 51% |
| 2 | 4 | 55% |
| 2 | 5 | 58% |
| 2 | 6 | 61% |
| - | - | - |
| 3 | 1 | 66% |
| 3 | 2 | 73% |
| 3 | 3 | 79% |
| 3 | 4 | 85% |

The tmpdir_stagger_phase_major and tmpdir_stagger_phase_minor correspond to the phase and step the plotting process is currently in.
For e.g. it could be 2:1 (2 is the phase or major, 1 is the step or minor).
You can view the current plotting phase:step in plotman interactive.
tmpdir_stagger_phase_major = 2 # phase 2
tmpdir_stagger_phase_minor = 1 # step 1
The tmpdir_stagger_phase_limit corresponds to the number of plot jobs that can be concurrently run before reaching phase 2, step 1 or 2:1.
If this is set to 2, then there will always be 2 plot jobs concurrently ran during phase 1.
Or specifically during (1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7).
tmpdir_stagger_phase_limit = 2 # limit of 2 plot jobs
You may decide you want to allow 3 conconcurrent plot jobs to run during phase 1.
Increase the tmpdir_stagger_phase_limit to 3.
tmpdir_stagger_phase_major = 2 # phase 2
tmpdir_stagger_phase_minor = 1 # step 1
tmpdir_stagger_phase_limit = 3 # limit of 3 plot jobs
You may decide you want to relax the restriction and expand the phase:step to 3:1, and increase the limit on jobs to 4.
tmpdir_stagger_phase_major = 3 # phase 3
tmpdir_stagger_phase_minor = 1 # step 1
tmpdir_stagger_phase_limit = 4 # limit of 4 plot jobs
