I am still waiting for a reply.

​please understand, that posting to this mailing list does not entitle you to get a response and part​icularly not on short notice.
there have only been 7 hours since your original post. 
this mailing list is a voluntary effort, which means that people may choose to not respond if:
- they don't have had time
- they don't understand what you are asking
- they don't know a good response
- they think, you should just follow the instructions in the manual
- they think, you should try out what your can figure out yourself and then report back with the details and errors, if any.
- they think, what you are asking for makes no sense
- they don't care

a typical rule of thumb for mailing lists is to give people at least two business days time to respond (keeping in mind that people may be located in different time zones and may have different holidays than you), before re-posting.

since the LAMMPS manual is quite detailed (sometimes too detailed), you can use that time to do some research there and perhaps it will lead you to the result you are looking for without having to repost your question.

...and after giving you a lecture on mailing list etiquette i have two comments:
- how to do what you want should be possible to figure out by carefully studying the documentation and readme files
- i don't see the point of using the intel compiler in this setup. you just make your life needlessly complicated. unlike with fortran, gcc is quite competitive and occasionally ahead of , and since you cannot use KOKKOS and USER-INTEL (the latter of which benefits a lot from using the intel compiler) at the same time, there really is not much of a reason to switch away from gcc. the performance critical part will be the GPU acceleration, anyway.

in addition to that, you don't even provide the bare minimum of useful information (LAMMPS version, intel compiler version, CUDA version, gcc version), and whether you have checked these against the list of tested/compatible combinations in the KOKKOS supporting information. in short, the better documented and detailed your inquiry, the better chances you get meaningful help (instead of getting dressed down publicly).



Thank you.

I want to use KOKKOS package (Cuda, OpenMP) with intel compiler.

what should i do in any *-kokkos makefile to get what i want ?
