Heiner Litz

2/4 “En4S: Enabling SLOs in Serverless Storage Systems”! Congratulations Minghao Xie, Chen Qian, and Heiner Litz!!

@bariskasikci @takhandipu Well deserved @takhandipu !

Proud advisor moment. Huge congrats to Tanvir Ahmed Khan @takhandipu for winning the ACM SIGARCH/ IEEE TCCA Outstanding Dissertation Award! Looking forward to all the amazing work Tanvir will do at Columbia!

@satnam6502 @headinthebox Every computation can be done manually using pen and paper. The only reason why we are using computers is speed. Performance matters.

@headinthebox I *love* computing, it is a religion to me. But not the graphs and charts.

I feel a lot of pressure to be a graphs and charts computer scientist, a quantitative computer scientist. I hate it, and I've spent most of my career doing exactly the opposite of what Hennessy and Patterson have espoused. I want to be qualitative computer scientist. I am very happy with the subjective rather than so called objective. I believe there is value in an idea or concept that does not need to be subjected to the Spanish Inquisition of a PLDI paper review. I believe there is truth in beauty, and it does not need to be measured by a Ruler.

Stanford MAST reunion at SoCC’23 :) @kozyraki @hlitz @kkaffes Great keynotes, research talks, posters and discussions about new directions in cloud computing!

@jasoneshraghian Beautiful Zermatt!

A nice writeup about the TPUv4 system based on a talk my colleagues Norm Jouppi and Andy Swing delivered at @hotchipsorg 2023 on Tuesday. Learn more about the reconfigurable optical network! servethehome.com/google-details…

🎉 Congratulations to Heiner Litz on his promotion to #BaskinEngineering associate professor! Litz conducts research in the fields of computer architecture & systems, with an emphasis on improving energy efficiency, cost, & performance. Learn more: people.ucsc.edu/~hlitz/ @hlitz

@takhandipu @bariskasikci Congratulations Tanvir, but even more to Columbia! Looking forward to more joint tears in the future!

@bariskasikci Thanks, Baris! Premium quality,😛

🥲 Proudest advisor tears. All the best, Tanvir!

@satnam6502 My guess: it is going to be Indian

Planning what to cook for our dinner guests tonight.

@djimeneth Aw sorry to miss it. Are these meta apples or real apples?

Some food at the HPCA/CGO/PPoPP coffee break. I'm giving the keynote tomorrow. Feedback on some slides included "deeply offensive." I fixed that part. Still, those apples are kind of hard and I'm not looking forward to their use by the audience as projectiles if things get ugly.

The beautiful @ucsc campus this morning

@EarlenceF @bariskasikci As a reviewer I am annoyed if I put in a lot of efforts into a review, have some concrete questions, and authors do not answer them due to word limits. The time required to read a long rebuttal is negligible compared to reviewing and discussing.

@EarlenceF @bariskasikci Weak rebuttals cause rejects which mean another reviewer is reading the whole paper again. It is actually more time efficient to read a long rebuttal.

So needlessly callous and officious. Let the reviewers ignore longer rebuttals if they want to. Why not have some empathy and forgiveness for the grad students that put in all the work?

Proud mentor moment! Yuxuan's (fling.seas.upenn.edu/~zyuxuan/) paper on Online COde Layout OptimizationS (OCOLOS, web.eecs.umich.edu/~takh/papers/z…) to perform profile-guided optimizations on a running process got selected for IEEE Micro Top Picks 2023.

Intel finally released (software.intel.com/sites/default/…) how to use the code prefetch hint instructions for their next-generation processors. Great to see our academic work getting traction in real-world processor design.

Computer Science and Engineering at UCSC has open faculty positions in storage, databases, and systems. Please apply here: lnkd.in/g34pd3az

BTW, these are BOLT speedups as well. Note 2x speedup on Verilator simulating a RISCV design, where PGO doesn't show much benefit.

Proud mentor moment! Last week @MicroArchConf, Yuxuan (fling.seas.upenn.edu/~zyuxuan/) presented OCOLOS, the first online code layout optimizations system for unmanaged languages.

🎉👏 Congratulations to #BaskinEngineering Assistant Professor of Computer Science and Engineering Heiner Litz for winning the Best Paper Award at the 2022 IEEE/ACM International Symposium on Microarchitecture (MICRO 22)! people.ucsc.edu/~hlitz/papers/… @hlitz
