As SCREAM-15 is being held in conjunction with HPDC'15, please see their site for all non-program information. Workshop participants must register through HPDC'15. Note that the early registration deadline is May 18.
HPDC'15 will also provide NSF-sponsored travel awards for students to attend the conference. Only students attending a US institution are eligible for the NSF travel support. Student authors for workshop papers are also eligible for these awards. Please see: http://www.hpdc.org/2015/registration/student-travel-grants/
