hwloc_topo...nd_support(3)

💖 hwloc_topology_membind_support 💖

okay so bestie, this page is from the Library Functions Manual, and the main character is hwloc_topology_membind_support — the memory-binding support flag moment for a topology. It’s giving “what bind stuff is actually supported around here?” ✨

---

✨ NAME ✨

hwloc_topology_membind_support — that’s the name, no cap. 💅

🎀 SYNOPSIS 🎀

First things first, queen: include the header.

#include <hwloc.h>

🦋 Data Fields 🦋

Here’s the full flag lineup, and yes, every single one is an unsigned char:

• unsigned char set_thisproc_membind
• unsigned char get_thisproc_membind
• unsigned char set_proc_membind
• unsigned char get_proc_membind
• unsigned char set_thisthread_membind
• unsigned char get_thisthread_membind
• unsigned char set_area_membind
• unsigned char get_area_membind
• unsigned char alloc_membind
• unsigned char firsttouch_membind
• unsigned char bind_membind
• unsigned char interleave_membind
• unsigned char nexttouch_membind
• unsigned char migrate_membind
• unsigned char get_area_memlocation
• unsigned char weighted_interleave_membind

🌸 Detailed Description 🌸

These are literally:

Flags describing actual memory binding support for this topology.

So like, this is the vibe check for memory-binding support on the topology. 🔥

And here’s the important caveat, bestie:

A flag may be set even if the feature isn't supported in all cases (e.g. binding to random sets of non-contiguous objects).

Translation: don’t assume a set flag means every possible wild case is covered. The original specifically calls out the “random sets of non-contiguous objects” example, so keep that in mind. 🫶

🔥 Field Documentation 🔥

unsigned char hwloc_topology_membind_support::alloc_membind

Allocating a bound memory area is supported — slay. 💖

unsigned char hwloc_topology_membind_support::bind_membind

The Bind policy is supported. Periodt. 👑

unsigned char hwloc_topology_membind_support::firsttouch_membind

The First-touch policy is supported. 🎀

unsigned char hwloc_topology_membind_support::get_area_membind

Getting the binding of a given memory area is supported. Got it, bestie. 🦋

unsigned char hwloc_topology_membind_support::get_area_memlocation

Getting the last NUMA nodes where a memory area was allocated is supported. That’s the tea. ☕

unsigned char hwloc_topology_membind_support::get_proc_membind

Getting the binding of a whole given process is supported. 💜

unsigned char hwloc_topology_membind_support::get_thisproc_membind

Getting the binding of the whole current process is supported. Hi bestie, that’s you. 🫶

unsigned char hwloc_topology_membind_support::get_thisthread_membind

Getting the binding of the current thread only is supported. Very “main character thread” energy. 🧚

unsigned char hwloc_topology_membind_support::interleave_membind

The Interleave policy is supported. 🌈

unsigned char hwloc_topology_membind_support::migrate_membind

Migration flags are supported. 🚀

unsigned char hwloc_topology_membind_support::nexttouch_membind

The Next-touch migration policy is supported. ✨

unsigned char hwloc_topology_membind_support::set_area_membind

Binding a given memory area is supported. 💅

unsigned char hwloc_topology_membind_support::set_proc_membind

Binding a whole given process is supported. 🔥

unsigned char hwloc_topology_membind_support::set_thisproc_membind

Binding the whole current process is supported. 👑

unsigned char hwloc_topology_membind_support::set_thisthread_membind

Binding the current thread only is supported. 🎀

unsigned char hwloc_topology_membind_support::weighted_interleave_membind

The Weighted interleave policy is supported. Iconic, honestly. 🌟

Cute sign-off time: the footer’s source/version is Hardware Locality (hwloc), Version 2.15.0, and the page name down there is hwloc_topo...nd_support(3). The original footer doesn’t print a separate date, so we’re not inventing one 😌. Bye bestie! 💖✨
