Basic-UI-for-GPT-J-6B-with-low-vram

A repository to run GPT-J-6B on low vram systems by using both ram, vram and pinned memory.

There seem to be some issues with the weights in the drive link. There seems to be some performance loss, most likely because of poor 16 bit conversion.

How to run :

Use - pip install git+https://github.com/finetuneanon/[email protected]
Use the link - https://drive.google.com/file/d/1tboTvohQifN6f1JiSV8hnciyNKvj9pvm/view?usp=sharing to dowload the model that has been saved as described here - https://github.com/arrmansa/saving-and-loading-large-models-pytorch

Timing (2000 token context)

1

system -

16 gb ddr4 ram . 1070 8gb gpu.
23 blocks on ram (ram_blocks = 23) out of which 18 are on shared/pinned memory (max_shared_ram_blocks = 18).

timing -

single run of the model(inputs) takes 6.5 seconds.
35 seconds to generate 25 tokens at 2000 context. (1.4 seconds/token)

system -

16 gb ddr4 ram . 1060 6gb gpu.
26 blocks on ram (ram_blocks = 26) out of which 18 are on shared/pinned memory (max_shared_ram_blocks = 18).

timing -

40 seconds to generate 25 tokens at 2000 context. (1.6 seconds/token)
