From 847fdee7c013455debef5e4194ade080b77b9b3a Mon Sep 17 00:00:00 2001 From: Spencer Bryngelson Date: Fri, 15 May 2026 01:00:02 -0400 Subject: [PATCH 01/30] improve: Intel GPU Max (Ponte Vecchio) OpenMP target offload support - Fix INTEL_COMPILER_ID Fypp variable: 'Intel' -> 'IntelLLVM' in shared_parallel_macros.fpp and omp_macros.fpp so Intel-specific OMP macro branches actually match for ifx builds - Add Intel-specific OMP directives in omp_macros.fpp: target teams loop (no bind/defaultmap clauses ifx rejects), OMP_MKL_DISPATCH() emitting ! dispatch for oneMKL GPU FFT - Add GPU_MKL_DISPATCH() in parallel_macros.fpp for oneMKL DFTI dispatch from device-mapped allocatables (Intel GPU FFT path) - CMakeLists.txt: - Fix Intel compiler ID checks: 'Intel' -> 'IntelLLVM' - Switch -fopenmp to -fiopenmp -fopenmp-targets=spir64 for ifx - Add -fpp to global IntelLLVM compile options - Compile mkl_dfti_omp_offload.f90 via add_custom_command with minimal flags (no -free -fpp) to avoid OpenMP 5.2 clause issues - Link -qmkl=parallel, libmkl_sycl_dft, libsycl, libOpenCL for Intel GPU FFT backend - Skip building FFTW from source for IntelLLVM (uses oneMKL) - m_fftw.fpp: Add Intel GPU path using oneMKL DFTI + ! dispatch for azimuthal Fourier filter; CPU path still uses FFTW for Intel - m_pressure_relaxation.fpp: Fix ifx SPIR64 bug -- change dimension(sys_size) -> dimension(:) in all declare-target helper interfaces to avoid llvm-spirv InvalidArraySize (SPIR-V requires compile-time constant array bounds; sys_size is a runtime value) - m_compute_levelset.fpp: Guard GPU_PARALLEL_LOOP with Fypp MFC_COMPILER != INTEL_COMPILER_ID for s_apply_levelset; ifx if-else dispatch to multiple declare-target routines in a target teams loop triggers LLVM dominance error, and the dispatch-wrapper fix triggers an ifx ICE -- host fallback is the only workaround - docs/documentation/intel-gpu-max.md: Document build environment, required library paths, known ifx bugs, and GPU device access Tested on GT CRNCH RoboGator (dash3): ifx 2025.3.3, oneMKL 2026.0, Intel Data Center GPU Max 1100 Co-Authored-By: Claude Sonnet 4.6 --- CMakeLists.txt | 54 ++++- docs/documentation/intel-gpu-max.md | 223 ++++++++++++++++++ src/common/include/omp_macros.fpp | 28 ++- src/common/include/parallel_macros.fpp | 8 + src/common/include/shared_parallel_macros.fpp | 2 +- src/simulation/m_compute_levelset.fpp | 19 +- src/simulation/m_fftw.fpp | 200 ++++++++++++++-- src/simulation/m_pressure_relaxation.fpp | 32 +-- toolchain/dependencies/CMakeLists.txt | 8 +- 9 files changed, 521 insertions(+), 53 deletions(-) create mode 100644 docs/documentation/intel-gpu-max.md diff --git a/CMakeLists.txt b/CMakeLists.txt index 72258149f3..8c0e0928d3 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -241,8 +241,9 @@ elseif (CMAKE_Fortran_COMPILER_ID STREQUAL "Flang") if (CMAKE_BUILD_TYPE STREQUAL "Debug" OR CMAKE_BUILD_TYPE STREQUAL "RelDebug") add_compile_options($<$:-O1> $<$:-g>) endif() -elseif (CMAKE_Fortran_COMPILER_ID STREQUAL "Intel") - add_compile_options($<$:-free>) +elseif (CMAKE_Fortran_COMPILER_ID STREQUAL "IntelLLVM") + add_compile_options($<$:-free> + $<$:-fpp>) if (CMAKE_BUILD_TYPE STREQUAL "Debug") add_compile_options(-g -Og -traceback -debug -check all) @@ -595,6 +596,47 @@ exit 0 HINTS "$ENV{OLCF_AFAR_ROOT}/lib" REQUIRED) target_link_libraries(${a_target} PRIVATE ${HIPFFT_LIB}) endif() + elseif(CMAKE_Fortran_COMPILER_ID STREQUAL "IntelLLVM") + # Intel GPU: oneMKL DFTI with !$omp dispatch for GPU FFT. + # Requires MKLROOT to be set (via oneAPI module or env). + if (NOT DEFINED ENV{MKLROOT}) + message(FATAL_ERROR "MKLROOT is not set.

No Intel-specific source workarounds +are needed for chemistry beyond the general levelset fix. + +To build and run a reactive chemistry case: +```bash +# Build (chemistry module generated automatically from cantera_file in case.py) +./mfc.sh run examples/1D_reactive_shocktube/case.py \ + --gpu mp --no-mpi -t pre_process simulation + +# Or bypass syscheck if no GPU render-group access: +cd examples/1D_reactive_shocktube +/path/to/build/install//bin/pre_process +OMP_TARGET_OFFLOAD=DISABLED \ + /path/to/build/install//bin/simulation +``` + +ifx warning during chemistry compilation: +``` +warning #8694: A procedure called by a procedure with the DECLARE TARGET +attribute must have the DECLARE TARGET attribute. [GET_MIXTURE_VISCOSITY_MIXAVG] +``` +This is a false positive from ifx's module-interface tracking; `m_thermochem.f90` +does declare all routines as target. The warning is harmless and the code runs +correctly. + ## GPU device access The Intel GPU requires membership in the `render` group (GID 109) to access From da087b02189bb1965ea6acb7d710cf20bbec9b15 Mon Sep 17 00:00:00 2001 From: Spencer Bryngelson Date: Fri, 15 May 2026 10:33:56 -0400 Subject: [PATCH 04/30] =?UTF-8?q?fix:=20ifx=20SPIR64=20InvalidArraySize=20?= =?UTF-8?q?=E2=80=94=20assumed-shape=20+=20local=20VLA=20fixes=20for=20Ope?= =?UTF-8?q?nMP=20device=20routines?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit --- src/common/m_boundary_common.fpp | 70 +++++++++++----------- src/common/m_chemistry.fpp | 4 +- src/common/m_helper.fpp | 20 +++---- src/common/m_phase_change.fpp | 40 ++++++------- src/common/m_variables_conversion.fpp | 24 ++++---- src/simulation/m_bubbles_EL.fpp | 38 ++++++------ src/simulation/m_compute_cbc.fpp | 74 ++++++++++++------------ src/simulation/m_hyperelastic.fpp | 28 ++++----- src/simulation/m_ib_patches.fpp | 28 ++++----- src/simulation/m_ibm.fpp | 4 +- src/simulation/m_igr.fpp | 10 ++-- src/simulation/m_pressure_relaxation.fpp | 4 +- src/simulation/m_qbmm.fpp | 8 +-- src/simulation/m_riemann_solvers.fpp | 6 +- src/simulation/m_sim_helpers.fpp | 22 +++---- src/simulation/m_viscous.fpp | 16 ++--- 16 files changed, 198 insertions(+), 198 deletions(-) diff --git a/src/common/m_boundary_common.fpp b/src/common/m_boundary_common.fpp index 6eb5383f75..33b874c9c5 100644 --- a/src/common/m_boundary_common.fpp +++ b/src/common/m_boundary_common.fpp @@ -284,11 +284,11 @@ contains subroutine s_ghost_cell_extrapolation(q_prim_vf, bc_dir, bc_loc, k, l, q_T_sf) $:GPU_ROUTINE(function_name='s_ghost_cell_extrapolation', parallelism='[seq]', cray_inline=True) - type(scalar_field), dimension(sys_size), intent(inout) :: q_prim_vf - integer, intent(in) :: bc_dir, bc_loc - integer, intent(in) :: k, l - integer :: j, i - type(scalar_field), optional, intent(inout) :: q_T_sf + type(scalar_field), dimension(:), intent(inout) :: q_prim_vf + integer, intent(in) :: bc_dir, bc_loc + integer, intent(in) :: k, l + integer :: j, i + type(scalar_field), optional, intent(inout) :: q_T_sf if (bc_dir == 1) then !< x-direction if (bc_loc == -1) then !

Fix: Use clang-offload-bundler to strip the SPIR-V device bundle from mkl_dfti_omp_offload.o, linking only host code. The MKL DFTI interface module (.modmic) is still compiled for use by dependent translation units, but ! dispatch for DFT calls falls back to CPU execution. 2. m_thermochem.f90 empty SPIR-V problem (chemistry/pyrometheus): Pyrometheus generates '#define GPU_ROUTINE(name) ! declare target' (a C macro). When ifx processes the file with -free -fpp, the Intel Fortran preprocessor strips '! declare target' after C macro expansion because '!' is treated as a Fortran comment character after expansion, leaving an empty SPIR-V bundle with no exported device symbols. Fix: Post-process generated m_thermochem.f90 to remove the #define macro and replace GPU_ROUTINE(name) call sites with literal '! declare target' directives, which are visible to the Fortran front-end.

At O0 the +crash does not occur (no inlining). Two fixes combined: + +1. **Split loops**: replaced the single if-else dispatch loop with one + `GPU_PARALLEL_LOOP` per geometry type so each kernel calls exactly one + declare-target routine. The original multi-callee dispatch also triggers + `"Instruction does not dominate all uses!"` in llvm-link. + +2. **Per-file `-fno-inline`**: in `CMakeLists.txt`, `set_source_files_properties` + adds `-fno-inline` to `m_compute_levelset.fpp.f90` for IntelLLVM+OpenMP + builds. This prevents the inliner from pulling declare-target routines into + the kernel body where they crash the SPIR-V backend. The routines remain + callable as proper device-side function calls via `!$omp declare target`. + +**`s_pressure_relaxation_procedure` (`m_pressure_relaxation.fpp`)** — SPIR-V +InvalidArraySize in declare-target helpers: + +`!$omp declare target (seq)` routines with `dimension(sys_size)` explicit-shape +dummy arguments trigger `"InvalidArraySize: Array size must be at least 1"` in +llvm-spirv. SPIR-V requires compile-time constant array bounds; `sys_size` is +a runtime module integer. Fixed by changing `dimension(sys_size)` → +`dimension(:)` (assumed-shape) on all helper routine interfaces. The loop now +runs on GPU for Intel. + +### syscheck GPU assertion +`syscheck` runs `assert(omp_get_num_devices() > 0)` and aborts if the GPU +is not accessible. This is a runtime check, not a build issue. See GPU device +access section above. + +To run a case anyway (testing code correctness on CPU fallback), invoke +`pre_process` and `simulation` directly from their install paths, bypassing +the `./mfc.sh run` wrapper that calls `syscheck` first. + +### `libumf.so.1` not found at runtime +The 2026.0 Level Zero and OpenCL UR adapters link against `libumf.so.1`. +If not in `LD_LIBRARY_PATH`, all adapters fail silently and sycl-ls reports +"No platforms found".
