Time Zone

The program is currently displayed in (GMT-04:00) Eastern Time (US & Canada).

Use conference time zone: (GMT-04:00) Eastern Time (US & Canada)Select other time zone

The GMT offsets shown reflect the offsets at the moment of the conference.

Time Band

By setting a time band, the program will dim events that are outside this time window. This is useful for (virtual) conferences with a continuous program (with repeated sessions).
The time band will also limit the events that are included in the personal iCalendar subscription service.

Abstract

GHC 8.10.1 offers a new latency-oriented garbage collector to complement the existing throughput-oriented copying collector. This demonstration discusses the pros and cons of the latency-optimized GC design, briefly discusses the technical trade-offs made by the design, and describes the sorts of application for which the collector is suitable. We include a brief quantitative evaluation on a typical large-heap server workload.
