The sole instance of this class is a process-wide singleton, similar to the NVVM interface. Initialization is protected by a lock and uses the standard (for Numba) open_cudalib function to load the NVRTC library. ) nvrtcVersionnvrtcCreateProgramnvrtcDestroyProgramnvrtcCompileProgramnvrtcGetPTXSize nvrtcGetPTXnvrtcGetCUBINSize nvrtcGetCUBINnvrtcGetProgramLogSizenvrtcGetProgramLogNct5|jddlm}tj |x|_} |d}|jjD]Q\}}t||}|d|_ |dd|_ tj|||dd}t|||Sddd|jS#t $r}d|_td|d}~wwxYw#1swY|jSxYw)Nr) open_cudalibr5zNVRTC cannot be loadedr)funcnamec||}|tjk(r t|tjk7r) t|j}d|d|}t |y#t $r d|d}Y%wxYw)Nz"Unknown nvrtc_result (error code: )zFailed to call z: )rr%r rrN ValueErrorr )rMrNargserror error_namemsgs r- checked_callz#NVRTC.__new__..checked_callxs $d  K$G$GG"7"99"k&?&??H-8-?-D-D %4D6J<"HC",S/1@$.H/>>CWA/G HsA A21A2) _nvrtc_lock_NVRTC__INSTANCEnumba.cuda.cudadrv.libsrLobject__new__OSErrorr _PROTOTYPESitemsgetattrrestypeargtypes functoolswrapssetattr) clsrLinstliberNprotorMrVs r-r[z NVRTC.__new__gs ~~%@(.s(;;M&w/C $(#3#3#9#9#;KD%"3-D#(8DL$)!"IDM__T*15D 2+ 2D$ 5'$<@~~5M%)CN+,DE1LM @~~s./C%CA.C% C" CC""C%%C9ct}t}|jt|t||j|jfS)zB Get the NVRTC version as a tuple (major, minor). )rrArvalue)r4majorminors r- get_versionzNVRTC.get_versions= %,e 5{{EKK''r,ct|tr|j}t|tr|j}t}|j t |||dddt ||S)z@ Create an NVRTC program with managed lifetime. rN) isinstancestrencode nvrtc_programrBrr/)r4srcrNr6s r-create_programzNVRTC.create_programs` c3 **,C dC ;;=D f sD!T4HD&))r,c|Dcgc]}|j}}|Dcgc] }t|}}tt|z}||} |j|jt||ycc}wcc}w#t $rYywxYw)z Compile an NVRTC program.
