c - Passing the PTX program to the CUDA driver directly -

the cuda driver api provides loading file containing ptx code filesystem. 1 following:

cumodule module; cufunction function;  const char* module_file = "my_prg.ptx"; const char* kernel_name = "vector_add";  err = cumoduleload(&module, module_file); err = cumodulegetfunction(&function, module, kernel_name); 

in case 1 generates ptx files during runtime (on fly) going through file io seems waste (since driver has load in again).

is there way pass ptx program cuda driver directly (e.g. c string) ?

taken ptxjit cuda example:

define ptx program c string as

char myptx32[] = "\n\     .version 1.4\n\     .target sm_10, map_f64_to_f32\n\     .entry _z8mykernelpi (\n\.param .u32 __cudaparm__z8mykernelpi_data)\n\     {\n\     .reg .u16 %rh<4>;\n\     .reg .u32 %r<8>;\n\      // other stuff      .loc    28      18      0\n\     exit;\n\     }\n\  "; 

then

 cumoduleloaddataex(phmodule, myptx32, 0, 0, 0); 

and finally

 cumoduleloaddataex(phmodule, myptx, 0, 0, 0);
