cuda-gpt's Introduction

Accelerated GPT in CUDA

Usage

Compile and Execute

nvcc *.cpp include/*.c* -o cu.out  -arch=sm_60 --use_fast_math

Modify include/parameter.h Line 142 from #define MAKETEMP 0to #define MAKETEMP 1 for table generations. Compile and execute. Then change back to #define MAKETEMP 0.

  • If the step above is not done then Cannot open the file! error will arise.

Tested on Tokyo Tech TSUBAME 3.0

  • Nvidia Tesla P100
  • Cuda compilation tools, release 8.0, V8.0.61

Known issues

minor result difference between CPU and GPU

  • Could be CPU precision error in multiplyVect3x3 used in bilinear_normal_projection function in stdGpt.cpp
