From 6eec49ed20fb3a8032718d5f4b9a3e774098df3f Mon Sep 17 00:00:00 2001 From: Sergey Sharybin Date: Mon, 5 Nov 2012 08:04:57 +0000 Subject: Cycles: memory usage report This commit adds memory usage information while rendering. It reports memory used by device, meaning: - For CPU it'll report real memory consumption - For GPU rendering it'll report GPU memory consumption, but it'll also mean the same memory is used from host side. This information displays information about memory requested by Cycles, not memory really allocated on a device. Real memory usage might be higher because of memory fragmentation or optimistic memory allocator. There's really nothing we can do against this. Also in contrast with blender internal's render cycles memory usage does not include memory used by scene, only memory needed by cycles itself will be displayed. So don't freak out if memory usage reported by cycles would be much lower than blender internal's. This commit also adds RenderEngine.update_memory_stats callback which is used to tell memory consumption from external engine to blender. This information is used to generate information line after rendering is finished. --- intern/cycles/blender/blender_session.cpp | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'intern/cycles/blender/blender_session.cpp') diff --git a/intern/cycles/blender/blender_session.cpp b/intern/cycles/blender/blender_session.cpp index 05db9f55380..01bd5f013e3 100644 --- a/intern/cycles/blender/blender_session.cpp +++ b/intern/cycles/blender/blender_session.cpp @@ -477,11 +477,15 @@ void BlenderSession::update_status_progress() float progress; double total_time; char time_str[128]; + float mem_used = (float)session->stats.mem_used / 1024.0f / 1024.0f; + float mem_peak = (float)session->stats.mem_peak / 1024.0f / 1024.0f; get_status(status, substatus); get_progress(progress, total_time); - timestatus = b_scene.name(); + timestatus = string_printf("Mem: %.2fM, Peak: %.2fM | ", mem_used, mem_peak); + + timestatus += b_scene.name(); if(b_rlay_name != "") timestatus += ", " + b_rlay_name; timestatus += " | "; @@ -494,6 +498,7 @@ void BlenderSession::update_status_progress() if(status != last_status) { b_engine.update_stats("", (timestatus + status).c_str()); + b_engine.update_memory_stats(mem_used, mem_peak); last_status = status; } if(progress != last_progress) { -- cgit v1.2.3
