We're excited to have @EthanCecchetti present Serif, his best-paper-winning @IEEESSP paper (w/ @AndrewCMyers) about protecting invariants in reentrant programs (like smart contracts) even in the presence of malicious code.
This Friday at noon, CIT 368 and on Zoom!

Today, we release Tuplex (tuplex.cs.brown.edu), a new system that turns Python data science pipelines into efficient, optimized machine code.
Think PySpark or Dask, but with end-to-end LLVM code generation for custom Python code. Tuplex often yields speedups of 10-20x. 🧵⏎

At HotOS today, Lily Tsai (@tslilyai) presents our work on making better privacy in web applications a reality through structured database transformations we call "disguises".
Check out her talk (youtu.be/kHRcPezOuR8) and tune in for discussion at 4:40pm Eastern!
ALT Talk title slide for "Privacy Heroes Need Data Disguises".

Today's systems seminar was by @refezs of @YaleCompsci on FPGA security in cloud datacenters: youtu.be/HQVkHPiWLkc
Did you know that you can "fingerprint" an individual FPGA on the cloud, and that an FPGA's temperature is a covert channel that can leak information?
Check out Friday's systems seminar talk by @RuanZain , on AIFM, a new approach to extending scarce server memory with remote ("far") memory: youtu.be/bFlRbeOxE5g
AIFM's userspace runtime avoids kernel overheads captures application semantics, achieving near-local memory perf.

This work is a collaboration between Zain, @ms705 of @SystemsAtBrown, @MarcosKAguilera of @vmwareresearch, and Adam Belay of MIT.
Today's systems seminar talk was by @arpanbg and @mpi_jcmace, on Clockwork, their new system for predictable DNN inference over shared GPUs: youtu.be/bc624Qs7oXw
Key take: meeting inference SLOs is easy if the serving infrastructure around the actual model is predictable

New paper on shared indexes ("arrangements") for stream processing! Joint work with @frankmcsherry of @MaterializeInc, and @utaal Mothy Roscoe of @SystemsGroupETH.
tl;dr: shared arrangements reduce new-query latency by 100x (no rebuilding of indexes) & memory footprint by 3x.

Congratulations to @rodrigo_fonseca and co-authors, who won the Community Award at @usenix ATC 2020 today for their paper "Serverless in the Wild"!
30 Jun 2020
Our upcoming @usenix ATC paper, Serveless in the Wild, has the 1st characterization of a #serverless provider workload, real traces, and a policy that reduces cold starts, saves resources, and is being deployed in production! microsoft.com/en-us/research… github.com/Azure/AzurePublic… #azure

Awesome week for Systems and Networks at Brown -- three (!) papers accepted at @ACMSIGCOMM and one at @VLDB2020! 🎉
The papers cover efficient stream processing, ML for CDN configs, formal verification of a WAN, and zero-downtime release deployment (details in thread below) ⬇️

3) Network verification (Da Yu, w/ @rodrigo_fonseca, @ennanzhai, @lampson0505): practical & algorithmic innovations for formal verification of @AlibabaGroup's WAN configuration, which prevented many misconfigurations & reduced the failure rate of updates by >50% in 2019 [SIGCOMM]

4) Zero downtime release (@usama6naseer & @DotTheophilus again, w/ @fb_research: @lvc4, @udippant, @ranj33th, Alan Frindell) discusses crucial components in Facebook infrastructure that sustain a high release frequency, without disrupting user connections and experience [SIGCOMM]
