[Libomptarget] Implement a unified kernel entry functionThis patch implements a unified kernel entry function that will betargeted from both teams and non-teams clauses. We introduce a newinterface and make the old functions call in using the new one. Afollowing patch will include the necessary changes to Clang to callthese new functions instead.Reviewed By: jdoerfertDifferential Revision: https://reviews.llvm.org/D128549 List of files: /llvm-project-15.0.7/openmp/libomptarget/src/exports

[OpenMP] Add dynamic memory function to omp.h and add documentationThis patch adds the `llvm_omp_target_dynamic_shared_alloc` function tothe `omp.h` header file so users can access it by default. Also changedthe name to keep it consistent with the other target allocators. Addedsome documentation so users know how to use it. Didn't add the interfacefor Fortran since there's no way to test it right now.Reviewed By: jdoerfertDifferential Revision: https://reviews.llvm.org/D123246 List of files: /llvm-project-15.0.7/openmp/libomptarget/src/exports

208f9005 - [Libomptarget] Add an external interface to dynamic shared memory

Fri, 01 Oct 2021 18:37:02 +0000

[Libomptarget] Add an external interface to dynamic shared memoryThis patch adds an external interface to access the dynamic sharedmemory buffer in the device runtime. The function introduced is``llvm_omp_get_dynamic_shared``. This includes a host-sidedefinition that only returns a null pointer so that it can be used whenhost-fallback is enabled without crashing. Support for dynamic sharedmemory was also ported to the old device runtime.Reviewed By: JonChesterfieldDifferential Revision: https://reviews.llvm.org/D110957 List of files: /llvm-project-15.0.7/openmp/libomptarget/src/exports

313c5239 - [OpenMP][Tool] Introducing the `llvm-omp-device-info` tool

Wed, 28 Jul 2021 02:38:27 +0000

[OpenMP][Tool] Introducing the `llvm-omp-device-info` toolThis patch introduces the `llvm-omp-device-info` tool, which uses theomptarget library and interface to query the device info from all theavailable devices as seen by OpenMP. This is inspired by PGI's `pgaccelinfo`Since omptarget usually requires a description structure with executablekernels, I split the initialization of the RTLs and Devices to be able toinitialize all possible devices and query each of them.This revision relies on the patch that introduces the print device info.A limitation is that the order in which the devices are initialized, and thecorresponding device ID is not necesarily the one seen by OpenMP.The changes are as follows:1. Separate the RTL initialization that was performed in `RegisterLib` to its own `initRTLonce` function2. Create an `initAllRTLs` method that initializes all available RTLs at runtime3. Created the `llvm-deviceinfo.cpp` tool that uses `omptarget` to query each device and prints its information.Example Output:```Device (0): print_device_info not implementedDevice (1): print_device_info not implementedDevice (2): print_device_info not implementedDevice (3): print_device_info not implementedDevice (4): CUDA Driver Version: 11000 CUDA Device Number: 0 Device Name: Quadro P1000 Global Memory Size: 4236312576 bytes Number of Multiprocessors: 5 Concurrent Copy and Execution: Yes Total Constant Memory: 65536 bytes Max Shared Memory per Block: 49152 bytes Registers per Block: 65536 Warp Size: 32 Threads Maximum Threads per Block: 1024 Maximum Block Dimensions: 1024, 1024, 64 Maximum Grid Dimensions: 2147483647 x 65535 x 65535 Maximum Memory Pitch: 2147483647 bytes Texture Alignment: 512 bytes Clock Rate: 1480500 kHz Execution Timeout: Yes Integrated Device: No Can Map Host Memory: Yes Compute Mode: DEFAULT Concurrent Kernels: Yes ECC Enabled: No Memory Clock Rate: 2505000 kHz Memory Bus Width: 128 bits L2 Cache Size: 1048576 bytes Max Threads Per SMP: 2048 Async Engines: Yes (2) Unified Addressing: Yes Managed Memory: Yes Concurrent Managed Memory: Yes Preemption Supported: Yes Cooperative Launch: Yes Multi-Device Boars: No Compute Capabilities: 61```Reviewed By: tianshilei1992Differential Revision: https://reviews.llvm.org/D106752 List of files: /llvm-project-15.0.7/openmp/libomptarget/src/exports

d2f85d09 - [OpenMP][Libomptarget] Adding `print_device_info` to RTL and `omptarget`

Wed, 28 Jul 2021 01:47:40 +0000

[OpenMP][Libomptarget] Adding `print_device_info` to RTL and `omptarget`This patch introduces a function in the device's plugin to print thedevice information. This patch relates to another patch that introducesa CLI tool to obtain the device information from the omplibrary directly.It is inspired by PGI's pgaccelinfo.The modifications are as follows:1. Introduce the optional `void __tgt_rtl_print_device_info(RTLdevID)` function into the RTL.2. Introduce the `bool __tgt_print_device_info(devID)` function into `omptarget` interface. Returns false if the RTL is not implemented3. Added `bool printDeviceInfo(RTLDevID)` to the `DeviceTy`4. Implement the `__tgt_rtl_print_device_info` for CUDA. Added additional CUDA Runtime calls.Reviewed By: jdoerfertDifferential Revision: https://reviews.llvm.org/D106751 List of files: /llvm-project-15.0.7/openmp/libomptarget/src/exports

2b6f2008 - [OpenMP] Add function for setting LIBOMPTARGET_INFO at runtime

Wed, 21 Apr 2021 21:31:09 +0000

[OpenMP] Add function for setting LIBOMPTARGET_INFO at runtimeSummary:This patch adds a new runtime function __tgt_set_info_flag that allows theuser to set the information level at runtime without using the environmentvariable. Using this will require an extern function, but will eventually beadded into an auxilliary library for OpenMP support functions.This patch required moving the current InfoLevel to a global variable which mustbe instantiated by each plugin.Reviewed By: jdoerfertDifferential Revision: https://reviews.llvm.org/D100774 List of files: /llvm-project-15.0.7/openmp/libomptarget/src/exports

Tue, 21 May 2019 19:35:02 +0000

[OpenMP][libomptarget] Enable requires flags for target libraries.Summary:Target link variables are currently implemented by creating a copy of the variables on the device side and unified memory never gets exploited.When the prgram uses the:```#pragma omp requires unified_shared_memory```directive in conjunction with a declare target link, the linked variable is no longer allocated on the device and the host version is used instead.This behavior is overridden by performing an explicit mapping.A Clang side patch is required.Reviewers: ABataev, AlexEichenberger, grokos, HahnfeldReviewed By: AlexEichenberger, grokos, HahnfeldSubscribers: Hahnfeld, jfb, guansong, jdoerfert, openmp-commitsTags: #openmpDifferential Revision: https://reviews.llvm.org/D60223llvm-svn: 361294 List of files: /llvm-project-15.0.7/openmp/libomptarget/src/exports

[libomptarget] Move header files and CMake library definitionFuture patches will add (private) header files in src/ that shouldnot be visible to plugins, so move the "public" ones to a newinclude/ directory. This is still internal in a sense that thecontained files won't be installed for the user.Similarly, the target agnostic offloading library should be builtdirectly in src/. The parent directory is responsible for findingdependencies and including all subdirectories.Differential Revision: https://reviews.llvm.org/D40797llvm-svn: 319968 List of files: /llvm-project-15.0.7/openmp/libomptarget/src/exports
