Pittsburgh Accommodations

If you are planning to arrive in Pittsburgh over the weekend preceding the retreat, PDL has several rooms on hold at each of the hotels listed below. When you call the hotel to make reservations, tell them that you'd like a room booked for the PDL Retreat (or quote the appropriate code listed below). You may also book extra nights at the preferred rate if you request them at the time of your booking.

Your room reservations for the nights of the Retreat itself (Oct. 28 and 29) will be taken care of by us, so you will only need a room at one of the following hotels if you are arriving early and staying past the Retreat.

Please make your reservations as early as possible, as there are several Pittsburgh events that may also make rooms scarce.

Through Hamerschlag Hall
Enter the front doors of Hamerschlag Hall from the campus mall. (Hamerschlag is the building with the cupola on top at the west end of campus.) Proceed to the staircase or the elevator at the end of HH first floor. Go down to level "B." Follow signs to REH. You will enter the Atrium next to Singleton.

From outside REH
Pass in front of Scaife Hall and follow the sidewalk on to the covered walkway above the service road. Proceed through the door into REH. The Singleton room will be on your left.

Bedford Springs Resort

Bedford Springs Resort is a four season, historically significant destination located on 2,200-acres. It began welcoming guests over 200 years ago when the mineral springs of Bedford Springs, PA became known as a source of rejuvenation. The resort is approximately 90 miles east of Pittsburgh.

CMU Retreat attendees and guests will travel to Bedford Springs on Monday, October 28 and return Wednesday, October 30. We will provide bus transportation to the resort on Monday and back to Pittsburgh and the Pittsburgh International airport on Wednesday afternoon.

Participants of the retreat will be members of the PDL Consortium and invited guests. Information on becoming a member of the consortium is available from Karen Lindenfelser, Bill Courtright (PDL Executive Director), or Greg Ganger (PDL Director).

VLIS Job Fair, Oct. 30, 2013

Recently, a new Big Data Systems track has been developed in one of our local Masters degree programs. The students involved can do a 6-month coop-style internship as the final stage of the degree. To help create matches for both those completing the degree in December (and thus seeking full-time jobs) and those looking for 2014 internships, we are organizing a special job fair to occur at CMU right after the PDL Retreat. Retreat attendees can take the bus back to campus to participate. Details will follow soon.

We expect that approximately 100 MS students from VLIS and CSD will be participating.  Arrangements are being made and an information website will soon be available.
