A gramaticalidade de num e numa pode ser confirmada em qualquer dicionário Por exemplo no Aulete (com abreviaturas desabreviadas): 1 Contração da preposição em com o artigo indefinido um: Vive num sítio no interior 2 Contração da preposição em com o numeral um: Num dos dedos havia a marca do anel
What is -lnuma and what program uses it for compilation? OpenMPI, and I think mpich2, uses libnuma (`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
Which architecture to call Non-uniform memory access (NUMA)? Technically, NUMA should probably only be used to describe non-uniform access latency or bandwidth to main memory (If the NUMA factor [latency far latency near or bandwidth far bandwidth near] is small [e g , comparable to dynamic variability due to DRAM row misses, buffering, etc ], then the system might still be considered UMA )
caching - Whats the difference between Sub-NUMA Clustering and . . . In the technical overview published by Intel, "Sub-NUMA Clustering" and "Hemisphere and Quadrant Modes" are described separately But the main difference between them is not clear In this answer, it says that "Inside quadrant or Hemisphere mode, the same LLC mapping is done as SNC, but it is exposed as one numa domain and one physical memory map "
windows - NUMA - Local memory - Stack Overflow Each node has a CPU and it's own memory bank When you boot it up, the total system memory is the total memory in the machine So any program can access all the memory regardless of where it is But since some memory regions are faster depending on whether it's local to the core that's accessing it, it is NUMA –
linux - How do I know if my server has NUMA? - Stack Overflow For me, dmesg also lacks mention of "NUMA", but I have no access to var log dmesg which need root privilege I run find proc|grep -i numa and saw some numa_maps files I guess this is also a symbol that NUMA is enabled –
memory allocation and access on NUMA hardware - Stack Overflow How does Linux model NUMA systems? The kernel detects that it's running on a multi-core machine and then detects how much hardware there is and what the topology is It then creates a model of this topology using the idea of Nodes A Node is a physical socket which contains a CPU (possibly with multiple cores) and the memory that is attached to it
parallel processing - C++ NUMA Optimization - Stack Overflow Now a new requirement is to run the software on systems with more than one NUMA-node The targeted OS is Windows 7 x64 I've performed several measurements and noticed that the execution time has been optimal when assigning the application to a single NUMA node and therefore wasting a complete processor
profiling - How to monitor NUMA interconnection (QPI UPI) bandwidth . . . The per core remote traffic can be used to gather thread level NUMA traffic Method to estimate NUMA throughput generated between threads You need to ensure that the threads generating the NUMA traffic are bound to dedicated cores That can be done programmatically or you can rebind the threads by using tools like hwloc-bind
