RTX3080 Performance

[jennijuju]

From s0nik42:

I test a new RTX3080 this morning. I get the same performance than RTX2080 for PC2

I don’t use the following variables, any ideas what value to set, and if it can improve that :

FIL_PROOFS_MAX_GPU_COLUMN_BATCH_SIZE
  FIL_PROOFS_COLUMN_WRITE_BATCH_SIZE
  FIL_PROOFS_MAX_GPU_TREE_BATCH_SIZE

that’s the ones I used :
declare -x BELLMAN_CPU_UTILIZATION=“0.875”
declare -x BELLMAN_CUSTOM_GPU=“GeForce RTX 3080:8704"
declare -x FIL_PROOFS_MAXIMIZE_CACHING=“1”
declare -x FIL_PROOFS_USE_GPU_COLUMN_BUILDER=“1"
declare -x FIL_PROOFS_USE_GPU_TREE_BUILDER=“1”

I get the same performance as RTX2080Ti for PC2 too

both 3080 and 2080Ti have the same 68 SM processor with each sm have 64 Int code command.

Hello,
for C2, the 3080 is not performing well

is there a way to configure the Chunk-size ? the value is very low compared to 1080Ti and 2080Ti, Thanks !

hi @jennijuju any news about the 3080 support ? if someone explain to me how to find the suitable parameters, I can run some test and benchmark.

Still nothing new on this topic?

I have a RTX 3080 - omitting the BELLMAN_CPU_UTILIZATION cut down C2 from ~85min to ~48min

I am also not defining BELLMAN_CUSTOM_GPU

Hope this helps.
