Dear All
I have been using coot as part of my normal workflow but since last
week I have been having issues with Coot after I built my own PC which
contains the following Hardware:
CPU - AMD Ryzen 9 5950X 16-Core Processor - 16 Cores, 32 Threads
RAM - 64 GB
GPU - AMD Radeon RX 6600 XT - Primary/Discrete
GPU VRAM - 8176 MB - GDDR6 2000 MHz
Despite the improvement in hardware, Coot is now having issues
refining molecules when using the ‘real space refine’ tool and other
related tools. When trying to refine, the program becomes stuttering
and slow such that it becomes unfeasible to use the program in a
reasonable amount of time. My current work around is to run Coot
through CCP4 cloud but this greatly slows down my workflow. >From what
I can see Coot is not be optimised for the AMD CPU.
You don't mention the operating system.
Maybe you have too many threads for Coot? Try setting the COOT_N_THREADS
to various values (starting, say, with 2) and see what happens.
But maybe it's a graphics (driver) issue and not a CPU/threads issue.
glxgears is the classic test for that.
