Program Schedule

The 36th International Workshop on Languages and Compilers for Parallel Computing

October 11-13, 2023, Lexington, Kentucky, USA

The tentative workshop schedule appears below. Note that due to scheduling difficulties, the banquet is now expected to be on Wednesday rather than Thursday, but there will be a less-formal event Thursday night too. You also can now register for the workshop. Registration is required for attendees, but is free and includes the banquet.

The space we will be using for the workshop is primarily the Hardymon Theater on the first floor of the Davis Marksbury Building. Professor Hank Dietz, the organizer for this year's LCPC, also has his office, research lab, and cluster computing machine room in this building. The research lab (room 108) and machine room (room 108A) are both just down the hall from the Hardymon Theater; the lab has plenty of space for attendees to do things ranging from temporarily storing luggage to having a quiet space for a Zoom meeting that they couldn't miss while attending LCPC.

The workshop technical content includes:

• 13 talks on peer-reviewed submitted research papers. Each talk will be given a 30-minute window; it is recommended that at least 5 minutes be left for questions.
• Two invited keynotes. Each keynote will be given a 60-minute window; it is recommended that at least 10 minutes be left for questions.
• Three invited panels. Each panel will be given a 60-minute window. The moderator will briefly introduce the panel topic and each panelist will present a 5-10 minute explanation of their position; the remainder of the time will be used for questions and discussion.
• Two invited papers. Each talk will be given a 30-minute window; it is recommended that at least 5 minutes be left for questions.

At your option, there are many things to do, including:

• There's a lot to do in Lexington, KY, and Marksbury and the suggested hotels are within walking distance of most things around downtown
• One of the big things happening October 6-28, 2023, is Keeneland's 2023 Fall Meet
• Visit UK Art Museum (1 block from Marksbury, takes about 1 hour, closes at 17:00)
• The University of Kentucky is Kentucky's flagship university, with many other things you might care to visit. If you just want to get a feel for the campus, you might find the Campus Tour Map useful.
