Additionally the following, or why not? Please comment on the one TODO which before your async re-work also was -- incorrectly? -- run asynchronously? commit 34c9ce65ad1f9865d0716d18c364d8c6928e694c Author: Thomas Schwinge <tho...@codesourcery.com> Date: Fri Dec 14 14:34:17 2018 +0100 into async re-work: more async function usage --- libgomp/oacc-parallel.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git libgomp/oacc-parallel.c libgomp/oacc-parallel.c index 5a441c9efe38..91875c57fc97 100644 --- libgomp/oacc-parallel.c +++ libgomp/oacc-parallel.c @@ -413,11 +413,11 @@ GOACC_enter_exit_data (int device, size_t mapnum, { case GOMP_MAP_ALLOC: case GOMP_MAP_FORCE_ALLOC: - acc_create (hostaddrs[i], sizes[i]); + acc_create_async (hostaddrs[i], sizes[i], async); break; case GOMP_MAP_TO: case GOMP_MAP_FORCE_TO: - acc_copyin (hostaddrs[i], sizes[i]); + acc_copyin_async (hostaddrs[i], sizes[i], async); break; default: gomp_fatal (">>>> GOACC_enter_exit_data UNHANDLED kind 0x%.2x", @@ -563,6 +563,8 @@ GOACC_update (int device, size_t mapnum, the value of the allocated device memory in the previous pointer. */ *(uintptr_t *) hostaddrs[i] = (uintptr_t)dptr; + /* This is intentionally no calling acc_update_device_async, + because TODO. */ acc_update_device (hostaddrs[i], sizeof (uintptr_t)); /* Restore the host pointer. */ Grüße Thomas
