[Nectarios Koziris]

Καλησπέρα σας και καλή ακαδημαϊκή χρονιά!

 

Μεθαύριο Πέμπτη 13/9 και ώρα 13:00 στην αίθουσα συνεδριάσεων της Σχολής
(εκεί που γίνονται οι Γενικές Συνελεύσεις, απέναντι από την βιβλιοθήκη της
Σχολής, στο ισόγειο του νέου κτιρίου) θα μας δώσει ομιλία ο παλαιός
απόφοιτος της Σχολής και του cslab, Αλέξανδρος Δαγκλής. Ο Αλέξανδρος έκανε
το διδακτορικό του στο EPFL με τον Babak Falsafi και από φέτος είναι
επίκουρος καθηγητής στο Georgia Tech στις ΗΠΑ.

 

Title:

Network-Centric Computing for Online Services

 

Abstract:

Modern datacenters offer an abundance of online services to billions of
daily users. The most demanding online services come with tight response
latency requirements, forcing service providers to keep their massive
datasets memory-resident, distributed across the datacenter's servers. Every
user request accesses the memory of hundreds of servers; therefore, fast
access to the aggregate memory pool is of crucial importance for service
quality. The entity binding all the memory resources together is the
datacenter network. Unfortunately, despite the dramatic evolution of
datacenter fabrics over the past decade, networking still incurs a latency
overhead of tens of microseconds to every remote memory access, making
memory pooling impractical. In this talk, I will propose a holistic
network-centric system redesign to enable memory pooling in future
datacenters, which includes (i) a specialized lightweight network stack;
(ii) on-chip integration of the network interface logic; and (iii) new
network operations with richer, end-to-end semantics. I will highlight the
role and demonstrate the effect of each of these three key features with
systems built throughout my dissertation.

 

Short bio:

Alexandros (Alex) Daglis is a recent graduate from EPFL, where he completed
his PhD under the supervision of Prof. Babak Falsafi and Prof. Edouard
Bugnion. His research interests lie in rack-scale computing and datacenter
architectures. Alex advocates tighter integration and co-design of network
and compute resources as a necessary approach to tackling the performance
overheads associated with inter-node communication in scale-out
architectures. He has been a founding member of Scale-Out NUMA, an
architecture, programming model, and communication protocol for low-latency,
distributed in-memory processing. Scale-Out NUMA has been prototyped and
awarded a US patent. As an intern at HP Labs, Alex worked on the design of
The Machine's unique memory subsystem. Starting in January 2018, Alex will
be joining Georgia Tech as an Assistant Professor.
