**Sector sizes** and **minimum pledged storage** required to mine blocks are two
|
|
|
|
|
|
very important Filecoin TestNet parameters that impact hardware decisions. We
|
|
|
|
|
|
will continue to refine all parameters during TestNet.

BECAUSE OF THIS, OUR STANDARD TESTING CONFIGURATION FOR FILECOIN MAINNET CAN AND
|
|
|
|
|
|
WILL CHANGE. YOU HAVE BEEN WARNED.

## Example configuration
|
|
|
|
|
|
|
|
|
|
|
|
The setup below is a minimal example for sealing 32 GiB sectors on Lotus:
|
|
|
|
|
|
|
2019-12-18 18:40:47 +00:00
|
|
|
|
- 2 TB of hard drive space.
|
|
|
|
|
|
- 8 core CPU
|
|
|
|
|
|
- 128 GiB of RAM
|
2019-12-11 12:29:48 +00:00
|
|
|
|
|
2019-12-18 18:40:47 +00:00
|
|
|
|
Note that 1GB sectors don't require as high of specs, but are likely to be
|
|
|
|
|
|
removed as we improve the performance of 32GB sector sealing.

## TestNet discoveries
|
|
|
|
|
|
|
2019-12-18 18:40:47 +00:00
|
|
|
|
- If you only have 128GiB of ram, enabling 256GB of **NVMe** swap on an SSD will
|
|
|
|
|
|
help you avoid out-of-memory issues while mining.

## Benchmarked GPUs
|
|
|
|
|
|

2019-12-18 18:40:47 +00:00
|
|
|
|
GPUs are a must for getting **block rewards**. Here are a few that have been
|
|
|
|
|
|
confirmed to generate **SNARKs** quickly enough to successfully mine blocks on
|
|
|
|
|
|
the Lotus TestNet.

## Testing other GPUs
|

|
|
|
|
If you want to test a GPU that is not explicitly supported, you can use the
|
|
|
|
|
|
following configuration flag:
|
2019-12-11 01:50:13 +00:00
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
|
BELLMAN_CUSTOM_GPU="<NAME>:<NUMBER_OF_CORES>"
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
Here is an example of trying a GeForce GTX 1660 ti with 1536 cores.
|
|
|
|
|
|
|
|
|
|
|
|
```sh
|
|
|
|
|
|
BELLMAN_CUSTOM_GPU="GeForce GTX 1660 Ti:1536"
|
|
|
|
|
|
```
|
|
|
|
|
|
|
2019-12-18 18:40:47 +00:00
|
|
|
|
To get the number of cores for your GPU, you will need to check your card’s
|
|
|
|
|
|
specifications.
