  • WARP_IPC_DEBUG Enables additional internal assertions and debug checks. Default: 0 (disabled) Set to 1 to enable.

  • TACCEL_PTX_DIR Overrides the default kernel cache directory used by Warp. Default: "./ptx/ptx_86" Used to store precompiled PTX files.

  • TACCEL_PTX_ARCH Sets the target CUDA PTX architecture. Default: 86 Must be an integer (e.g., 86 for SM_86 architecture). Invalid values will raise a ValueError.
