Hardware locality (hwloc)
### What version of hwloc are you using? Latest git (057fc67b3dd91fd1f251c39c3aa1465f18e83554) ``` ./utils/lstopo/lstopo --version lstopo 2.9.0a1-git ``` ### Which operating system and hardware are you running on? * Ubuntu 22.04...
For 3.0, I'd like to cleanup object subtypes. OS devs have an integer attribute that can be: * OFED and NET: The separation isn't clear when Ethernet NICs can do...
Some virtual environment (at least Microsoft Azure) expose PCI domains > 16bits to be sure they don't conflict with ACPI PCI domains (on 16bits) when using PCI pass through etc....
`hwloc-calc -N gpu` now counts only GPUs intead of all osdevs, same with -I (since 2.9) We could also support NUMA subtypes (DRAM, NVM, SPM, HBM) but this may require...
~~`hwloc-calc -H numa.core` is rejected because NUMA nodes aren't CPU objects. The reason behind is that multiple NUMA can be local to a single PU, and they may even be...
I'm a PhD student interested in finding security vulnerabilities in open source projects. We found a total of 01 warnings (indicating potential vulnerabilities) when running the CogniCrypt static analyzer (*)...
Given a specific core (or maybe whatever object), find a way to check whether any thread is bound to it. This was requested for threads within a single process (to...
If a NUMA node contains CPUs but its memory is offline for now and exposed as DAX (either because its non-volatile or soft-reserved), we should be able to attach that...
That's for later, but writing it down while I think about it. Linux is considering adding a readfile system call, possibly in time for Linux 5.7: ssize_t readfile(int dfd, const...
Currently, hwloc can export hardware and network locality for applications to obtain and set their affinity. However, in many scenarios, the information provided by the topology is not enough, for...
