    Project mention: Boehm Garbage Collector | news.ycombinator.com | 2024-01-21

    Due to the nature of web engine workloads migrating objects to being GC'd isn't performance negative (as most people would expect). With care it can often end up performance positive.

    There are a few tricks that Oilpan can apply. Concurrent tracing helps a lot (e.g. instead of incrementing/decrementing refs, you can trace on a different thread), in addition when destructing objects, the destructors typically become trivial meaning the object can just be dropped from memory. Both these free up main thread time. (The tradeoff with concurrent tracing is that you need atomic barriers when assigning pointers which needs care).

    This is on top of the safey improvements you gain from being GC'd vs. smart pointers, etc.

    One major tradeoff that UAF bugs become more difficult to fix, as you are just accessing objects which "should" be dead.

    Project mention: Jagged edges on everything, regardless of AA settings | /r/EliteDangerous | 2023-12-11

    If you are interested in making it look even better, then installing ReShade and adding FSAA there also makes a huge improvement over the best settings in game.

  • WorkOS

  • fully-homomorphic-encryption

    An FHE compiler for C++

    Project mention: What are the current hot topics in type theory and static analysis? | /r/ProgrammingLanguages | 2023-05-08

    Secure computing. This includes Fully Homomorphic Encryption AKA FHE, of which there is a language/compiler which just got released and Google's older FHE compiler. FHE is probably more "compiler" than "type system", e.g. Google's compiler works on C++. Also Security Type Systems which include Oblivious data structures and Oblivious ADTs.

  • ispc

    Intel® Implicit SPMD Program Compiler

    Project mention: Implementing a GPU's Programming Model on a CPU | news.ycombinator.com | 2023-10-14

    This so-called GPU programming model has existed many decades before the appearance of the first GPUs, but at that time the compilers were not so good like the CUDA compilers, so the burden for a programmer was greater.

    As another poster has already mentioned, there exists a compiler for CPUs which has been inspired by CUDA and which has been available for many years: ISPC (Implicit SPMD Program Compiler), at https://github.com/ispc/ispc .

    NVIDIA has the very annoying habit of using a lot of terms that are different from those that have been previously used in computer science for decades. The worst is that NVIDIA has not invented new words, but they have frequently reused words that have been widely used with other meanings.

    SIMT (Single-Instruction Multiple Thread) is not the worst term coined by NVIDIA, but there was no need for yet another acronym. For instance they could have used SPMD (Single Program, Multiple Data Stream), which dates from 1988, two decades before CUDA.

    Moreover, SIMT is the same thing that was called "array of processes" by C.A.R. Hoare in August 1978 (in "Communicating Sequential Processes"), or "replicated parallel" by Occam in 1985 or "PARALLEL DO" by "OpenMP Fortran" in 1997-10 or "parallel for" by "OpenMP C and C++" in 1998-10.

    The only (but extremely important) innovation brought by CUDA is that the compiler is smart enough so that the programmer does not need to know the structure of the processor, i.e. how many cores it has and how many SIMD lanes has each core. The CUDA compiler distributes automatically the work over the available SIMD lanes and available cores and in most cases the programmer does not care whether two executions of the function that must be executed for each data item are done on two different cores or on two different SIMD lanes of the same core.

  • mrustc

    Alternative rust compiler (re-implementation)

    Project mention: Why do lifetimes need to be leaky? | /r/rust | 2023-12-08

    No, you don't. Existential proof: mrustc ignores lifetimes. Just flat out simply ignores. It changes some corner-cases related to HRBT, yet rustc compiled by mrustc works (that's BTW mrustc exist: to bootsrap the rustc compiler).
