@WeiqunZhang just a quick note if you haven't seen it yet: there is still an issue with the patches from #1852 applied |

Ok, removed the macOS linker flag work-arounds to fix that platform :) Not sure what we do about the |

Looks like we have a problem with Windows. |

Hm, but we do export those symbols on Windows with a blanket option developed by CERN. Maybe the logic it uses does not apply to Very off topic:
:D I mean that will fall on our feet as well at some point, e.g. if a users tries to import multiple amrex-powered libraries into an executable. I guess you are aware of that, sorry for mumbling out loud. For another time... we can think how to refactor those patterns for better C/C++-level composability :) |

Ah yes, the problem is with globals in AMReX: https://stackoverflow.com/a/54568678/2719194 We just need to add another macro for those (and long term avoid global states for better modularity). |

Is that true we have mark all the static variables and functions in classes with AMREX_EXPORT?

Note that these are not static variables at file scopes.

Only static (and export) variables, since they are encapsulated global states of a library.
static functions don't need that, as they do not carry a state.

In general, for modern C++ libs that template a lot one would manually expose only the public classes with such a macro and use -fvisibility=hidden -fvisibility-inlines-hidden.
Incomplete ramblings with mention of some benefits / Q&A: memo I wrote a while back: https://gist.github.com/ax3l/ba17f4bb1edb5885a6bd01f58de4d542
We don't do this and instead simplify through an export of all symbols by making everything visible by default (classes, functions, enums) - even for Windows; but the tooling for Windows does not include those global variables (data symbols).

We changed it to be an alias of The_Arena to avoid memory fragmentation. However, the issue is we don't have an Arena that can allocate non-managed memory unless The_Arena is not managed. Because of performance concerns, we sometimes want to allocate non-managed memory. Therefore, we make The_Device_Arena an alias if and only if The_Arena is not managed. commit ab8c892 Author: Weiqun Zhang <WeiqunZhang@lbl.gov> Date: Wed Oct 26 15:59:39 2022 -0700 Add alias template Gpu::NonManagedDeviceVector (AMReX-Codes#2999) commit b3e0a62 Author: Weiqun Zhang <WeiqunZhang@lbl.gov> Date: Wed Oct 26 15:02:13 2022 -0700 Pre- and Post-interpolation hook interface (AMReX-Codes#2991) Support both Fab and MultiFab versions of pre- and post-interpolation hooks.

Previously the only "user" type is ext_dir (external Dirichlet). The BC types are passed from the user's code to FillPatch, which in turn passes them back to the user provided BC filling function. These new types will make it easy for the user to determine the user defined BC types in their BC filling functions. commit 9502b99 Author: Weiqun Zhang <WeiqunZhang@lbl.gov> Date: Tue Oct 18 10:20:06 2022 -0700 Add BCRec::set for convenience (AMReX-Codes#2993) commit 4dbfbac Author: Thierry Antoun <thierry.antoun@ensta-paris.fr> Date: Mon Oct 17 15:05:54 2022 -0700 Adding AMReX_RESTRICT for GPU Test commit 7051a6c Author: Thierry Antoun <thierry.antoun@ensta-paris.fr> Date: Mon Oct 17 15:03:19 2022 -0700 Modyfing RedistributeMPI to make it work with 2 ranks commit 56b6402 Author: Weiqun Zhang <WeiqunZhang@lbl.gov> Date: Sat Oct 15 14:59:38 2022 -0700 ParallelFor with compile time optimization of kernels with run time parameters (AMReX-Codes#2954) Branches inside ParallelFor can be very expensive. If a branch uses a lot of resources (e.g., registers), it can significantly affect the performance even if at run time the branch is never executed because it affects the GPU occupancy. For CPUs, it can affect vectorization of the kernel. The new ParallelFor functions use C++17 fold expression to generate kernel launches for all run time variants. Only one will be executed. Which one is chosen at run time depends the run time parameters. The kernel function can use constexpr if to discard unused code blocks for better run time performance. Here are two examples of how to use them. int runtime_option = ...; enum All_options : int { A0, A1, A2, A3}; // Four ParallelFors will be generated. ParallelFor(TypeList<CompileTimeOptions<A0,A1,A2,A3>>{}, {runtime_option}, box, [=] AMREX_GPU_DEVICE (int i, int j, int k, auto control) { ... if constexpr (control.value == A0) { ... } else if constexpr (control.value == A1) { ... } else if constexpr (control.value == A2) { ... else { ... } ... }); and int A_runtime_option = ...; int B_runtime_option = ...; enum A_options : int { A0, A1, A2, A3}; enum B_options : int { B0, B1 }; // 4*2=8 ParallelFors will be generated. ParallelFor(TypeList<CompileTimeOptions<A0,A1,A2,A3>, CompileTimeOptions<B0,B1> > {}, {A_runtime_option, B_runtime_option}, N, [=] AMREX_GPU_DEVICE (int i, auto A_control, auto B_control) { ... if constexpr (A_control.value == A0) { ... } else if constexpr (A_control.value == A1) { ... } else if constexpr (A_control.value == A2) { ... else { ... } if constexpr (A_control.value != A3 && B_control.value == B1) { ... } ... }); Note that that due to a limitation of CUDA's extended device lambda, the constexpr if block cannot be the one that captures a variable first. If nvcc complains about it, you will have to manually capture it outside constexpr if. The data type for the parameters is int. Thank Maikel Nadolski and Alex Sinn for showing us the meta-programming techniques used here. commit bcbf17f Author: Weiqun Zhang <WeiqunZhang@lbl.gov> Date: Fri Oct 14 19:48:14 2022 -0700 2D RZ solver for WarpX: Arbitrary coefficient (AMReX-Codes#2986) The assumption in the 2D RZ solver for WarpX used to be there was no sigma_r (i.e., sigma_r == 1). In this PR, we allow arbitrary sigma_r coefficient. commit 9a3cd5d Author: Axel Huebl <axel.huebl@plasma.ninja> Date: Fri Oct 14 17:27:41 2022 -0700 CMake Docs: Fix User-Guidance (Link) (AMReX-Codes#2990) Update the user-guidance on CMake dependency linking to CMake 3.0+ (anno. 2014+). Seen in AMReX-Codes#2978 commit 1ad4144 Author: Weiqun Zhang <WeiqunZhang@lbl.gov> Date: Fri Oct 14 10:36:17 2022 -0700 Runge-Kutta support for AMR (AMReX-Codes#2974) This adds RK2, RK3 and RK4 in a new namespace RungeKutta. Together with the enhanced FillPatcher class, these functions can be used for RK time stepping in AMR simulations. A new function AmrLevel::RK is added for AmrLevel based codes. See CNS::advance in Tests/GPU/CNS/CNS_advance.cpp for an example of using the new AmrLevel::RK function. The main motivation for this PR is that ghost cell filling for high order (> 2) RK methods at coarse/fine boundary is non-trivial when there is subcycling. Co-authored-by: Jean M. Sexton <jmsexton@lbl.gov> commit c841ae8 Author: Weiqun Zhang <WeiqunZhang@lbl.gov> Date: Fri Oct 14 10:03:34 2022 -0700 Fourth-order interpolation from fine to coarse level (AMReX-Codes#2987) For fourth-order finite-difference methods with data at cell centers, we cannot use the usual averageDown function to overwrite coarse level data with fine data. We actually need to do interpolation. commit 975b830 Author: Weiqun Zhang <WeiqunZhang@lbl.gov> Date: Fri Oct 14 09:53:22 2022 -0700 Fix EB data inconsistency when fixing small cells and multiple cuts (AMReX-Codes#2943) ## Summary For consistency, we need to call the function that zeros out the level set even if that box does not have any small cells or multiple cuts. This is because a node could exist in multiple boxes. Furthermore, a covered cell or covered face may have a node with a level set < 0. ## Additional background This is usually not an issue. However, in WarpX, we use the level set to decide whether a node is an unknown in the linear system. The inconsistency makes the solver fail in some cases. commit 9c2264b Author: Axel Huebl <axel.huebl@plasma.ninja> Date: Fri Oct 14 07:41:06 2022 -0700 `MFIter::Finalize`: Free `m_fa` (AMReX-Codes#2988) This `free` should potentially not be delayed until the destructor is called.

The idea about this is, that we can call this already before destruction in Python, where `for` loops do not create scope. This function must be robust enough to be called again in the constructor (or we need to add an extra bool to guard that it is not called again in the destructor).

It's not as general as the various FillPatch functions (e.g., FillPatchTwoLevels). However, it can reduce the amount of communication data. Suppose we use RK2 with subcycling and the refinement ratio is 2. For each step on level 0, there are two steps on level 1. With RK2, each fine step needs to call FillPatch twice. So the total number of FillPatch calls is 4 in the two fine steps. Using the free function, one ParallelCopy per FillPatch call is needed for copying coarse data for spatial interpolation. With the FillPatcher class, two ParallelCopy calls will be done to copy old and new coarse data. Then these data will be used in the four FillPatcher::fill calls. This new approach saves two ParallelCopy calls per coarse step for a two levels run. It could save more if the time stepping requires more substeps or the refinement ratio is higher. Note that many of our AMReX codes use a time stepping algorithm that needs only one FillPatch call per step. For those codes, this new approach will not save any communication for a refinement ratio of 2. However, it will save communication when the refinement ratio is 4. commit 1bc4e4e Author: Weiqun Zhang <WeiqunZhang@lbl.gov> Date: Mon Oct 3 16:50:45 2022 -0700 Remove sycl namespace alias (AMReX-Codes#2971) This causes a conflict with new compilers. commit de7b7f4 Author: Weiqun Zhang <WeiqunZhang@lbl.gov> Date: Mon Oct 3 14:06:58 2022 -0700 Fix Tensor Solver BC (AMReX-Codes#2930) This fixes some bugs in the physical domain BC of tensor linear solver. At the corner of two no-slip walls (e.g., (0,0)), we have u(-1,0) = -u(0,0) and u(0,-1) = -u(0,0). It's incorrect to fill the corner ghost cell with u(-1,-1) = u(-1,0) + u(0,-1) - u(0,0), because it will result in u(-1,-1) = -3 * u(0,0). In the old approach, to avoid branches in computing transverse derivatives on cell faces, we fill the ghost cells first. For example, to compute du/dy at the lo-x boundary, we use the data in i = -1 and 0, just like we compute du/dy(i) using u(i-1) and u(i) for interior faces. The problem is the normal velocity in the ghost cells outside a wall is filled with extrapolation of the Dirichlet value (which is zero) and more than 1 interior cells. Because of the high-order extrapolation, u(-1) != -u(0). This is the desired approach for computing du/dx on the wall. However, this produces incorrect results in dudy. In the new approach, we explicitly handle the boundaries in the derivative stencil. For example, to compute transverse derivatives on an inflow face, we use the boundary values directly.

For some codes, it makes ParallelFor with many if statements on CPU much slower than without vectorization. Unfortunately, it does not have an ivdep pragma.

This is useful for restarting with a larger amr.max_level. The issue is we build EB at the finest level first and then coarsen it to the coarse levels. If the restart run has a different finest level, the EB on the coarse levels could be different without using this new capability. commit 6ebf8ff Author: Jon Rood <jon.rood@nrel.gov> Date: Thu Aug 4 14:32:59 2022 -0600 Add rpath to lib64 for ZFP.

Also, make DeriveFuncFab a std::function<> instead of plain function-pointer. ## Additional background We have been implementing small-plots for outputing variables at gauges (e.g. pressure at specific gauge locations). We may want to output the derived variable pressure only, and not all state-variables. The if-condition was incorrect in this case. Further, multi-material simulations require a material index in order to compute derived variables, in addition to existing parameters. Making DeriveFuncFab a std::function is sufficient for our purposes. commit ce0fb74 Author: Andrew Myers <atmyers2@gmail.com> Date: Tue Jul 26 16:20:38 2022 -0700 Fix host / device sync bug in PODVector (AMReX-Codes#2890) commit 06753e6 Author: Axel Huebl <axel.huebl@plasma.ninja> Date: Tue Jul 26 12:54:35 2022 -0700 `TagBoxArray::collate`: Fujitsu Clang (AMReX-Codes#2889) `mpiFCC -Nclang` only defines `__CLANG_FUJITSU`, not `__FUJITSU` as in the classic compiler mode. commit 7cf77dc Author: Weiqun Zhang <WeiqunZhang@lbl.gov> Date: Tue Jul 26 11:01:21 2022 -0700 MinLoc and MaxLoc Support (AMReX-Codes#2885) Add struct ValLocPair that can be used by ReduceOps/ReduceData and ParReduce to find the location of the min/max value.

These issues seem to be related to the use of MPI Gatherv with MPI_Datatype. This PR implements a possible workaround, initially proposed by @WeiqunZhang . The idea is that, when WarpX is compiled with the Fujitsu compiler, simpler integer arrays instead of MPI_Datatype are used in the routine where the issue was observed. commit 7660c88 Author: Weiqun Zhang <WeiqunZhang@lbl.gov> Date: Fri Jul 8 08:48:14 2022 -0700 Allow zero components MultiFab and BaseFab (AMReX-Codes#2873) This is useful for particle I/O that does not have any mesh data. yt needs a header file associated with a MultiFab. commit c849dd1 Author: Weiqun Zhang <WeiqunZhang@lbl.gov> Date: Fri Jul 8 08:06:37 2022 -0700 New EB optimization parameter: eb2.num_coarsen_opt (AMReX-Codes#2872) At the beginning of EB generation, we chop the entire finest domain into boxes and find out the type of the boxes. We then collect the completely covered boxes and cut boxes into two BoxArrays. This process can be costly because of the number of calls to the implicit functions. In this commit, we have introduced a new ParmParse parameter, eb2.num_coarsen_opt with a default value of zero. If for instance it is set to 3, we start the box type categorization at a resolution that is coarsened by a factor of 2^3. For the provisional cut boxes, we refine them by a factor of 2, Then we chop them into small boxes and categorize the new boxes. This process is performed recursively until we are at the original finest resolution. The users should be aware that, if eb2.num_coaren_opt is too big, this could produce in erroneous results because evaluating the implicit function on coarse boxes could miss fine structures in the EB. Thank Robert Marskar for sharing this algorithm. commit 557aae8 Author: Erik <epalmer@lbl.gov> Date: Wed Jul 6 08:54:24 2022 -0700 point to new location of AMReX images, AMReX website repo (AMReX-Codes#2867) commit cbdc658 Author: Axel Huebl <axel.huebl@plasma.ninja> Date: Tue Jul 5 01:41:03 2022 +0200 SENSEI 4.0: Fix Build for Particles (AMReX-Codes#2869) ## Summary This part causes a compile error now in WarpX. cc @burlen @kwryankrattiger ## Additional background X-ref: Blocks WarpX 22.07 release ECP-WarpX/WarpX#3211 Follow-up to: - AMReX-Codes#2785 - AMReX-Codes#2834 commit dc8b734 Author: Andrew Myers <atmyers2@gmail.com> Date: Fri Jul 1 17:19:20 2022 -0700 Cache the neighbor comm tags for the CPU implementation of fillNeighbors.
