[Chromium-dev] Overlap the execution of SPU?

[Daniel <zd...@zj...>]

Hello,

I'm using Chromium in a 10 nodes cluster with one client and nine servers which form a 3x3 passive stereo display. Each node is equipt with double Xeon 2.4G CPU, 1G memory, GeForce 5200 with PCI-X bus. They are connected by Giga Ethernet.

However, the speed is always below my expectation. Rendering of a moderate size object with about 60K triangles needs about 0.6~1 seconds, which only need 0.04~0.05s on a single nodes.

I analyzed the problem carefully. I do think there are several issues may be considered to optimize Chromium. One possible way is overlaping the execution of SPU. If the network send/rec and rendering can be overlapped, then lots of time will be saved. And if every SPU spawns one thread, the stream may be parallized to utilize the SMP nodes, may it? 

Another problem: I find that Chromium doesn't consider load balance in Tiled display wall. Can we add one in it?
