From 6c84c8bf9b29ce89f5d263c1fa3630896fcb23f4 Mon Sep 17 00:00:00 2001 From: "Maciej W. Rozycki" Date: Sun, 22 Dec 2019 19:54:09 +0000 Subject: 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.
