Fix OpenACC "ephemeral" asynchronous host-to-device copies
This patch fixes several places in libgomp/target.c where "ephemeral" data (on the stack or in temporary heap locations) may be used as the source of an asynchronous host-to-device copy that may not complete before the host data disappears. An existing, but flawed, workaround for this problem in the AMD GCN libgomp offloading plugin is currently present on mainline, and was posted for the og9 branch here: https://gcc.gnu.org/legacy-ml/gcc-patches/2019-08/msg00901.html and previous versions of this patch were posted here (for mainline/og9): https://gcc.gnu.org/legacy-ml/gcc-patches/2019-11/msg01482.html https://gcc.gnu.org/legacy-ml/gcc-patches/2019-09/msg01026.html libgomp/ * libgomp.h (gomp_copy_host2dev): Update prototype. * oacc-mem.c (memcpy_tofrom_device, update_dev_host): Add new argument to gomp_copy_host2dev (false). * plugin/plugin-gcn.c (struct copy_data): Remove free_src field. (copy_data): Don't free src. (queue_push_copy): Remove free_src handling. (GOMP_OFFLOAD_dev2dev): Update call to queue_push_copy. (GOMP_OFFLOAD_openacc_async_host2dev): Remove source-data snapshotting. (GOMP_OFFLOAD_openacc_async_dev2host): Update call to queue_push_copy. * target.c (goacc_device_copy_async): Add SRCADDR_ORIG parameter. (gomp_copy_host2dev): Add EPHEMERAL parameter. Snapshot source data when true, and set up deferred freeing of temporary buffer. (gomp_copy_dev2host): Update call to goacc_device_copy_async. (gomp_map_vars_existing, gomp_map_pointer, gomp_attach_pointer) (gomp_detach_pointer, gomp_map_vars_internal, gomp_update): Update calls to gomp_copy_host2dev with appropriate ephemeral argument. * testsuite/libgomp.oacc-c-c++-common/async-data-1-1.c: Remove XFAIL.

libgomp: Structure element mapping for OpenMP 5.0
This patch implement OpenMP 5.0 requirements of incrementing/decrementing the reference count of a mapped structure at most once (across all elements) on a construct. This is implemented by pulling in libgomp/hashtab.h and using htab_t as a pointer set. Structure element list siblings also have pointers-to-refcounts linked together, to naturally achieve uniform increment/decrement without repeating. There are still some questions on whether using such a htab_t based set is faster/slower than using a sorted pointer array based implementation. This is to be researched on later. libgomp/ChangeLog: * hashtab.h (htab_clear): New function with initialization code factored out from... (htab_create): ...here, adjust to use htab_clear function. * libgomp.h (REFCOUNT_SPECIAL): New symbol to denote range of special refcount values, add comments.

openacc: Deep copy attach/detach should not affect reference counts
Attach and detach operations are not supposed to affect structural or dynamic reference counts for OpenACC. Previously they did so, which led to subtle problems in some circumstances. We can avoid reference-counting attach/detach operations by extending and slightly repurposing the do_detach field in target_var_desc. It is now called is_attach to better reflect its new role. 2020-07-27 Julian Brown <julian@codesourcery.com> Thomas Schwinge <thomas@codesourcery.com> libgomp/ * libgomp.h (struct target_var_desc): Rename do_detach field to is_attach. * oacc-mem.c (goacc_exit_datum_1): Add assert.

openacc: Adjust dynamic reference count semantics
This patch adjusts how dynamic reference counts work so that they match the semantics of the source program more closely, instead of representing "excess" reference counts beyond those that represent pointers in the internal libgomp splay-tree data structure.

openmp: Add basic library allocator support.
This patch adds very basic allocator support (omp_{init,destroy}_allocator, omp_{alloc,free}, omp_[sg]et_default_allocator). The plan is to use memkind (likely dlopened) for high bandwidth memory, but that part isn't implemented yet, probably mlock for pinned memory and see what other options there are for other kinds of memory. For offloading targets, we need to decide if we want to support the dynamic allocators (and on which targets), or if e.g. all we do is at compile time replace omp_alloc/omp_free calls with constexpr predefined allocators with something special. And allocate directive and allocator/uses_allocators clauses are future work too. 2020-05-19 Jakub Jelinek <jakub@redhat.com> * omp.h.in (omp_uintptr_t): New typedef. (__GOMP_UINTPTR_T_ENUM): Define.

Add OpenACC 2.6 `acc_get_property' support
Add generic support for the OpenACC 2.6 `acc_get_property' and `acc_get_property_string' routines, as well as full handlers for the host and the NVPTX offload targets and minimal handlers for the HSA, Intel MIC, and AMD GCN offload targets. Included are C/C++ and Fortran tests that, in particular, print the property values for acc_property_vendor, acc_property_memory, acc_property_free_memory, acc_property_name, and acc_property_driver. The output looks as follows: Vendor: GNU Name: GOMP Total memory: 0 Free memory: 0 Driver: 1.0 with the host driver (where the memory related properties are not supported for the host device and yield 0, conforming to the standard) and output like: Vendor: Nvidia Total memory: 12651462656 Free memory: 12202737664 Name: TITAN V Driver: CUDA Driver 9.1 with the NVPTX driver. 2019-12-22 Maciej W.

[libgomp, nvptx] Fix libgomp.c/target-5.c compilation
Libgomp test-case libgomp.c/target-5.c is failing to compile when building for x86_64 with nvptx accelerator due to missing: - getpid - gethostname - isatty (pulled in by fwrite) in the nvptx newlib. This patch fixes the build failure by: - adding a function gomp_print_string which limits the use of fwrite to a single location (in affinity-fmt.c), and - creating an nvptx version of affinity-fmt.c, which: - overrides the configure test results HAVE_GETPID and HAVE_GETHOSTNAME, and - implements fwrite using write. Build and reg-tested on x86_64 with nvptx accelerator. 2018-12-13 Tom de Vries <tdevries@suse.de> * affinity-fmt.c (gomp_print_string): New function, factored out of ... (omp_display_affinity, gomp_display_affinity_thread): ... here, and ... * fortran.c (omp_display_affinity_): ... here. * libgomp.h (gomp_print_string): Declare. * config/nvptx/affinity-fmt.c: New file. Include affinity-fmt.c, undefining HAVE_GETPID and HAVE_GETHOSTNAME, and mapping fwrite to write. From-SVN: r267100 |
