Message
<expression text> should be a dynamic library. The dynamic library should supply wrapped kernel functions.
Detailed Help
The CUDA* application expects <expression text> to be the name of a CUDA module. The user should ensure that the CUDA code that generated the CUDA module is migrated to SYCL* code and compiled to generate a kernel library.
Suggestions to Fix
The user should find the module source files that are used to make the CUDA module and migrate them to SYCL using the --extra-arg=-ptx option of Intel® DPC++ Compatibility Tool to generate wrapped kernel functions:
dpct <module source file(s)> --extra-arg=--ptx
The migrated module source file(s) should be compiled to make a kernel library.
On Linux*:
icpx -fsycl <migrated module source file(s)> -fPIC -shared -o <kernel library filename>
On Windows*:
icpx -fsycl <migrated module source file(s)> -shared -o <kernel library filename>
The <kernel library filename> should be chosen so that <expression text> will have the same filename at runtime. For the following example, <kernel library filename> should be set to library.so.
For example, this original CUDA code:
char *ptxFile = "module.ptx"; cuModuleLoad(&module, ptxFile);
results in the following migrated SYCL code:
char *ptxFile = "module.ptx"; module = dpct::load_kernel_library(ptxFile);
which is rewritten to:
char *libraryFile = "library.so"; module = dpct::load_kernel_library(libraryFile);
