Managed to setup Grin node, wallet etc… (Debian 9) just as described in the getting started tutorial. I cannot get grin-miner to properly use my 1080tis. When I connect to grin-pool I get:
Connection Status: Connected to Grin [etc…]
Mining Status: Starting miner and awaiting first graph time
The console shows two cuckatoo_mean_cuda plugins (same issues happen with cuckaroo) with the same device ID number. My config file specifies two different device names. Nvidia-smi says that neither of my cards is being used so it feels like the miner cannor activate my GPUs. For the record even using a config script with only one GPU gives the same exact problems.
I wonder if maybe grin-miner is attempting to launch the GPU that operates my display or something. It isn’t very clear to me how the miner chooses which GPU to operate.
#UPDATE
If I select the ocl_cuckaroo plugin my GPUs manage to mine. Why won’t the cuda specific plugins work though?
Here’s my config:
log_to_stdout = true
stdout_log_level = “Info”
log_to_file = true
file_log_level = “Debug”
log_file_path = “grin-miner.log”
log_file_append = true

stratum_server_addr = “eu.stratum.grin-pool.org:3416”
stratum_server_login = “MY_USER”
stratum_server_password = “MY_PASS”
