About lmeyerov

CEO @ Graphistry

Twitter: LMeyerov

We're 100X'ing investigations with the first GPU visual graph AI platform and now Louie.AI, the genAI-first rethink of analyst notebooks. We enjoy working with data teams all the way from from tech companies and startups to scientists and government agencies, and on problems from threat hunting, fraud, & misinformation to supply chain, user journey, and genomics. Our partners include Amazon, Nvidia, and more.

* Louie.ai: Louie connects to your data systems so analysts can use natural language to ask questions and get back data, analyses, AI models, interactive visualizations, and everything else the Graphistry platform can do

* Graph visual analytics: Gartner measured graph as a Top 5 growing data technology for the next 5 years and awarded us as the 2021 Cool Vendor in Graph

* End-to-end GPU computing: Apache Arrow & RAPIDS.ai were both voted top data projects of 2020 & 2021

* Point-and-click workflow automation: Process automation is the fastest growing enterprise industry in history

* Graph AI (GNNs) to make it easy for operational teams to take the next step of their graph journey by automating their graph insights for tasks like detection: Winner of the 2022 US Cyber Command AI alert data challenge!

... And we're hiring! LLM app/backend engineering, AI (cyber, GNNs, ...), sales engineering, platform engineering, UI, and more: https://www.graphistry.com/careers

    A graph is a fancy way of saying a few async await calls, which a REPL can do (We added the same to louie.ai, not complicated)

    Fwiw, without naming names, I helped someone at a hackathon make their first app on something he was passionate about, later found out he had been recently homeless living on an ab…

    agreed. gfql already gives this best-of-both for oss cpu+gpu cypher as we've been steadily working through benchmarks like ldbc, pokec, etc. The HPC lessons for graph algorithms is…

    see graph500 we use igraph cpu / cugraph gpu in pygraphistry/gfql projects, and our experience is cugraph is ~10X+ on tiny cheap GPUs over igraph. looking at that table, where all …

    cudf+cugraph are the table+graph algorithms that started around that same time to align with it, that's what helped get arrow funded from the nvidia side can't reply on the below, …

    cudf/cugraph is open source and helped fund the arrow ecosystem , I think it's good to give teams credit when they do work they didn't have to do and not misrepresent them. And yes…

    We shared with the author how databricks multi-node and single-node graphframes were wildly inefficient for this kind of thing: we were measuring doing billion-edge graph traversal…

    Not really ;-) ~10 years ago, we helped create apache arrow, helped create GPU data frames, and been running for the last decade the open source pygraphistry and now gfql cpu+gpu p…

    Related, we recently release the polars version of GFQL, the only oss cypher property graph query engine for CPU+GPU, and even better, no database nor outside process needed. We st…

    I strongly disagree ;-) The paper's line of reasoning seems to continue the endless subjective loop of assuming your viz framework has the right abstractions & defaults , which the…

    This feels like a bit of a semantic debate, but maybe a few useful perspectives, as interpret current bespoke work as not so rosy wrt collapse: - Synthetic datasets are typically h…

    I've been calling this Software Collapse It's the same problem that AI faces of Model Collapse: AIs that train on the internet ultimately just end up training on one another, stop …

    I have to wonder: What's the open protocol - some sort of LTAP read/write path - for compute engines to target LTAP / lakebases? Sort of like how iceberg > deltalake, except now on…

    Fable adds guard rails like cyber refusals to mythos. Mythos is the starting point for fable. Same model family.

    AOP is a big influence for how we are designing hooks, including custom ones, for louie.ai's agent harness. More principled structure to what is already expected. I'm unclear on AO…

    We almost went with Om for our seed round, and he remains on my list of "one of the good ones". It's rare to meet folks where that becomes so apparent so quick.

    curious how folks like to measure this stuff wrt load testing? We are actively revisiting our traffic simulation approach, and a surprisingly non-obvious part has been which charts…

    Comment #48563832

    Any thoughts on layering on-GPU work stealing or cudf on top? For gfql (graph query language mapping down to cudf calls), we're trying to jettison the hot loop of python->cpu->gpu,…

    I don't have a horse in this race, but for anyone who has worked in it, "science advances one funeral at a time" comes to mind here

    This is a funny one because it seems less into what fable is being clever on and more about the bitter lesson and data flywheels Our UX agentic engineering flow, as many others, is…
