Resolved the issue

I had mistakenly selected

   Enable OpenMP Offloading | Generate Device Binary for Intel GPU's

instead of

   Enable OpenMP Offloading | Generate x86 + SPIR64 fat binary

 

*** However ***

Using the same project that had mistakenly used Generate Device Binary for Intel GPU's

And changing the Code Generation to Generate x86 + SPIR64 fat binary

Would produce a failing application.

    forrtl: severe (151): allocatable array is already allocated

If I do a Build | Clean, the build

Then build

LINK : fatal error LNK1181: cannot open input file 'x64\Debug\GPUtest.obj'

However the compilation of GPUtest succeeded (no error listed)

*** I had to create a new project to undo the Generate Device Binary for Intel GPU's

 

It appears that something is sticking around in the project folder should you mistakenly select

     Enable OpenMP Offloading | Generate Device Binary for Intel GPU's

     build

    Enable OpenMP Offloading | Generate x86 + SPIR64 fat binary

I can run dpc++ test programs

ifx under Windows is the issue.

module mod_GPUtest
real(8), allocatable :: CPUarray(:,:)
real(8), allocatable :: GPUarray(:,:)
end module mod_GPUtest
    
program GPUtest
    use omp_lib
    use mod_GPUtest
    implicit none
    allocate(CPUarray(3,10000))
    !$omp allocate allocator(omp_target_shared_mem_alloc)
    allocate(CPUarray(3,10000))
end program GPUtest
GPUtest.f90

@jimdempseyatthecove 

Are you compiling from the oneAPI command prompt?  What compiler options are you using?
Add option "-#" and see what the driver is feeding the compiler and linker.

Build log written to  "file://C:/test/GPUtest/GPUtest/x64/Debug/BuildLog.htm"
GPUtest - 2 error(s), 1 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
========== Build completed at 10:00 AM and took 00.626 seconds ==========

 

Additional information

If I launch MS VS Community 2020 from the start (Windows Search) I get the missing ocloc as shown above.

 

If I launch a oneAPI command prompt,

then issue devenv to launch MS VS Community 2020,

open my solution then build

Error: Device name missing.
Command was: ocloc -file C:\Users\jim00\AppData\Local\Temp\17368323llvm-spirv2.out -output_no_suffix -spirv_input -output C:\Users\jim00\AppData\Local\Temp\17368911llvm-spirv.out -options "-g -cl-opt-disable -cl-take-global-address -cl-match-sincospi"
Link: error #10401: error running 'Offline Compiler'

 

There appears to be two issues

 

1) MS VS environment is not setup for ifx offloading (I can work around this by running devenv from oneAPI command prompt)

2) Possibly my error in not specifying a device name (Intel(R) Arc(TM) Pro B50 Graphics)

When I run DPCPP, it seems to work without issue.

Apparently I must include the target device name in the project build properties? How?

Resolved the issue

I had mistakenly selected

   Enable OpenMP Offloading | Generate Device Binary for Intel GPU's

instead of

   Enable OpenMP Offloading | Generate x86 + SPIR64 fat binary

 

*** However ***

Using the same project that had mistakenly used Generate Device Binary for Intel GPU's

And changing the Code Generation to Generate x86 + SPIR64 fat binary

Would produce a failing application.

    forrtl: severe (151): allocatable array is already allocated

If I do a Build | Clean, the build

Then build

LINK : fatal error LNK1181: cannot open input file 'x64\Debug\GPUtest.obj'

However the compilation of GPUtest succeeded (no error listed)

*** I had to create a new project to undo the Generate Device Binary for Intel GPU's

 

It appears that something is sticking around in the project folder should you mistakenly select

     Enable OpenMP Offloading | Generate Device Binary for Intel GPU's

     build

    Enable OpenMP Offloading | Generate x86 + SPIR64 fat binary
