Limiting CPU usage #48

Open adamkglaser opened 5 years ago

adamkglaser commented 5 years ago

Hello, We are running BigStitcher on the Administrator account of our lab server (running Windows Server 2016). In Fiji, I have limited the resources to use only 50% of the server's CPU and RAM. When I run the fusion step in BigStitcher, I see that the RAM is limited, however the CPU does not seem to be limited. And it always uses all cores on the server. Is this a bug - or is there another way to explicitly limit how much CPU BigStitcher uses? Thanks! Adam

Hi, did you set it in edit options memory & threads? How does windows show hyper threading?

Yep I set the options under edit -> memory & threads. This might be a naive question, but how do I check if Windows is doing hyper threading? I assume it is, our server has 2x CPUs at 8 cores each, and when I open resource monitor there are 16 CPUs on Nodes 1 and 2 (so 32 CPUs total).
