### Environment variables
|
||
|
|
|
||
|
|
Ensure that workers have access to the following environment variables when they run.
|
||
|
|
|
||
|
|
```
|
||
|
|
export TMPDIR=/fast/disk/folder3 # used when sealing
|
||
|
|
export MINER_API_INFO:<TOKEN>:/ip4/<miner_api_address>/tcp/<port>/http`
|
||
|
|
export BELLMAN_CPU_UTILIZATION=0.875 # optimal value depends on exact hardware
|
||
|
|
export FIL_PROOFS_MAXIMIZE_CACHING=1
|
||
|
|
export FIL_PROOFS_USE_GPU_COLUMN_BUILDER=1 # when GPU is available
|
||
|
|
export FIL_PROOFS_USE_GPU_TREE_BUILDER=1 # when GPU is available
|
||
|
|
export FIL_PROOFS_PARAMETER_CACHE=/fast/disk/folder # > 100GiB!
|
||
|
|
export FIL_PROOFS_PARENT_CACHE=/fast/disk/folder2 # > 50GiB!
|
||
|
|
|
||
|
|
# The following increases speed of PreCommit1 at the cost of using a full
|
||
|
|
# CPU core-complex rather than a single core.
|
||
|
|
# See https://github.com/filecoin-project/rust-fil-proofs/ and the
|
||
|
|
# "Worker co-location" section below.
|
||
|
|
export FIL_PROOFS_USE_MULTICORE_SDR=1
|
||
|
|
```
|
||
|
|
|
||
|
|
### Run the worker
|
||
|
|
|
||
|
|
```
|
||
|
|
lotus-worker run <flags>
|
||
|
|
```
|
||
|
|
|
||
|
|
These are old flags:
|
||
|
|
|
||
|
|
```
|
||
|
|
--addpiece enable addpiece (default: true)
|
||
|
|
--precommit1 enable precommit1 (32G sectors: 1 core, 128GiB RAM) (default: true)
|
||
|
|
--unseal enable unsealing (32G sectors: 1 core, 128GiB RAM) (default: true)
|
||
|
|
--precommit2 enable precommit2 (32G sectors: multiple cores, 96GiB RAM) (default: true)
|
||
|
|
--commit enable commit (32G sectors: multiple cores or GPUs, 128GiB RAM + 64GiB swap) (default: true)
|
||
|
|
```
|
||
|
|
|
||
|
|
We added two new flags:
|
||
|
|
|
||
|
|
```
|
||
|
|
--windowpost enable windowpost (default: false)
|
||
|
|
--winnningpost enable winningpost (default: false)
|
||
|
|
```
|
||
|
|
|
||
|
|
These post flags have priority over old flags. If you want this worker to be a window post machine, you can just set the windowpost flag to be `true`. Similar to winning post machine. If you set both of them to be `true`, it will be a window post machine.
