Transparent memory offloading: more memory at a fraction of the cost and power
Transparent memory offloading: more memory at a fraction of the cost and power Transparent memory offloading (TMO) is Meta’s data center solution for offering more memory at a fraction of the cost and power of existing technologies In production since 2021, TMO saves 20 percent to 32 percent of memory per server across millions of servers in our data center fleet We are witnessing massive growth i
Algorithms for Modern Hardware - Algorithmica
This is an upcoming high performance computing book titled “Algorithms for Modern Hardware†by Sergey Slotin. Its intended audience is everyone from performance engineers and practical algorithm researchers to undergraduate computer science students who have just finished an advanced algorithms course and want to learn more practical ways to speed up a program than by going from $O(n \log n)$ to $
GitHub - koute/bytehound: A memory profiler for Linux.
Can be used to analyze memory leaks, see where exactly the memory is being consumed, identify temporary allocations and investigate excessive memory fragmentation Gathers every allocation and deallocation, along with full stack traces Can dynamically cull temporary allocations allowing you to profile over a long period of time Uses a custom, tailor-made stack unwinding implementation which makes i
GitHub - GrapheneOS/hardened_malloc: Hardened allocator designed for modern systems. It has integration into Android's Bionic libc and can be used externally with musl and glibc as a dynamic library for use on other Linux-based platforms. It will gain mor
This is a security-focused general purpose memory allocator providing the malloc API along with various extensions. It provides substantial hardening against heap corruption vulnerabilities. The security-focused design also leads to much less metadata overhead and memory waste from fragmentation than a more traditional allocator design. It aims to provide decent overall performance with a focus on
ImDisk Toolkit
This tool will let you mount image files of hard drive, cd-rom or floppy, and create one or several ramdisks with various parameters. This all-in-one package includes the ImDisk Virtual Disk Driver (2.1.1), the DiscUtils library that extends the number of supported image file formats, and adds several GUIs and features. 64-bit: https://sourceforge.net/projects/imdisk-toolkit/files/20240210/ImDiskT
GitHub - facebookincubator/oomd: A userspace out-of-memory killer
Out of memory killing has historically happened inside kernel space. On a memory overcommitted linux system, malloc(2) and friends usually never fail. However, if an application dereferences the returned pointer and the system has run out of physical memory, the linux kernel is forced to take extreme measures, up to and including killing processes. This is sometimes a slow and painful process beca
Finding And Fixing Node.js Memory Leaks: A Practical Guide
Fixing memory leaks may not be not the shiniest skill on a CV, but when things go wrong on production, it's better to be prepared! After reading this article, you'll be able to monitor, understand, and debug the memory consumption of a Node.js application. When Memory Leaks Become A ProblemMemory leaks often go unnoticed. They become a problem when someone pays extra attention to the production pe
Copy-on-write friendly Python garbage collection
At Instagram, we have the world’s largest deployment of the Django web framework, which is written entirely in Python. We began using Python early on because of its simplicity, but we’ve had to do many hacks over the years to keep it simple as we’ve scaled. Last year we tried dismissing the Python garbage collection (GC) mechanism (which reclaims memory by collecting and freeing unused data), and
