Intel Xeon Gold with 2 sockets
« on: October 08, 2018, 12:20:14 PM »
Hi. i have an intel xeon gold with two sockets/fisical processors.
I have noticed that photoscan only uses one socket/CPU. Is this by default?
Can it use the full power of my machine with two sockets and a quadro P5000?

Hello FOSI,

Which OS version you are using? Are you observing similar effect of one socket utilization for other resource-intensive applications? Probably there are some system settings defined that are blocking the utilization of both sockets for certain applications?

PhotoScan by default is using all available CPU resources, provided by the system.
Best regards,

Windows 10 Pro for workstations
Intel Xeon Gold 6140

Only software to date that i see that used all sockets is autodesk Recap pro, when importing/indexing scans

other software like Leica cyclone only uses one socket.

PhotoScan supports up to 64 logical processors and only one NUMA node。

If you have options for NUMA on your motherboard, try adjusting them.
