GPU is not a CPU, so the basic chip architecture doesn't support OS, drivers, etc. This is partly why you don't see GbE or Infiniband on GPU boards. If they had high-speed, low-latency I/O, then handling something like video transcoding over network packets would be much higher performance. As it stands, every network packet has to transit the motherboard, Linux, possible VM layer, PCIe bus... then back again. Obviously not high performance. -Jeff > From: pjsip-bounces@xxxxxxxxxxxxxxx [mailto:pjsip-bounces at lists.pjsip.org] > On Behalf Of Fedot Fedotov > Sent: Sunday, August 26, 2012 4:36 PM > To: pjsip list > Subject: Re: How to use GPU for accelerate video encoding. > > > > Hi! > > Maybe you can give me your sources and I'll try to explore they deeper? > And in which manner I can manage my GPU to use it as calculation center for > PJSIP operations? > > On Thu, Aug 23, 2012 at 11:26 PM, Trent Creekmore <tcreek at gmail.com> wrote: > > I came across this maybe a month ago on someone's blog, or a tech reporting > site. > > > > They were reporting poor results with encoding/decoding with GPUs.
