Sempre ouço pessoas falando coisas como: Eu estou numa boa. Vamos num show? É correto esse uso? Ou simplesmente seria uma abreviação?
According to wiki: Non-uniform memory access (NUMA) is a computer memory design used in multiprocessing, where the memory access time depends on the memory location relative to a processor. But it...
Dei-me conta recentemente que a contração da preposição em com os pronomes indefinidos — num, numa e plurais — é no Brasil por muitos considerada apropriada apenas em registos informais e tem vind...

NUMA sensitivity First, I would question if you are really sure that your process is NUMA sensitive? In the vast majority of cases, processes are not NUMA sensitive so then any optimisation is pointless. Each application run is likely to vary slightly and will always be impacted by other processes running on the machine.
You can simplify Quadrant and Hemisphere modes as a kind of "automagic" SNC (Sub NUMA Clustering) for non-NUMA aware software but it's not exactly like that. This Xeon Phi (KNL) presentation, this Intel's patent and your original 4th generation Xeon Scalable product overview helped me link the pieces together. Core counts in mainstream Xeon Scalable processors are approaching the core counts ...
OpenMPI, and I think mpich2, uses (`a simple programming interface to the NUMA (Non Uniform Memory Access) policy supported by the Linux kernel') for memory affinity -- to ensure that the memory for a particular MPI task stays close to the core that the task is running on, as vs. being kept in cache on another socket entirely. This is important for performance on multicore nodes. You may need ...
fd_shmem: unexpected numa_cnt 0 (expected in [1,1024]) Is there any way to "enable" NUMA nodes in a Docker container? I understand they're a hardware concept, so perhaps it's just not possible if the host doesn't have NUMA nodes, even in Docker Desktop where I believe a VM is involved.
