Dear Filippo and GPU developers,<br>
<br>
I find the new optionĀ "--with-pinned-mem" for the v5.3 QE-GPU but I
am not sure what effect it has on the system memory.<br>
<br>
My server has total of 144GB RAM and 8x C2050. These cards have 3GB
memory each, so there are 24 GB of video RAM. If I compile px-gpu.x
with the option "--with-pinned-mem", does it lock 24GB of system
memory out of 144 GB? and I will have 120 GB system RAM left?<br>
<br>
This may not be an issue for the old C2050, but if I go for 8x k80
and these cards have 24GB memory each, then it may be a problem. The
locked memory will become 192 GB which is more than the main system
memory of 144 GB, so it does not work?<br>
<br>
Please advise and thank you!<br>
<br>
Regards,<br>
Rolly<br>
