Travel Recommendations for Participants

When we began planning the IHPCSS more than a year ago, we could not have foreseen the current challenges caused by recent US immigration orders. For the IHPCSS, there are two primary challenges: the safety of our US students and instructors who may not be allowed back into the country if the IHPCSS was relocated, and the ability for students and instructors to travel to the US and return home from the US safely. Our ability to ensure both the safety of our students and instructors is of paramount importance to us. 

The IHPCSS organizing committee is monitoring how to best ensure the safety of our students and instructors while maintaining guiding principals of inclusiveness and merit-based, peer-reviewed candidate selection. IHPCSS selects candidates in a blind selection process that ensures selection is based on merit and free from bias. We are committed to building a diverse,open, and accessible experience for all of our students.

We encourage all who are interested to apply, even though some will have legitimate concerns about travel.  We will do our best to facilitate your travel to the US should you be accepted to the International HPC Summer School. In the event that accepted participants are unable to attend the IHPCSS because of travel restrictions, they will be offered a spot in the 2018 IHPCSS, which will be held in Europe

Planning an event of this kind is a yearlong effort, and the location for the summer school was set many months ago, long before the current uncertain travel situation.  It is unfortunately too late to change the location to another country, which would still create an uncertain situation for some of the participants returning to the US after the event.

Our current choices are to either proceed with the summer school at the planned location, or provide no one with the opportunity to attend.  Given those choices, we will proceed the best we can to help as many students participate as possible.

In the meantime, please follow these points of advice if you wish to apply:

  1. Investigate your need for a visa or other travel documentation prior to application;

  2. Apply for a visa as early as possible after you've been selected;

  3. Work closely with your local international affairs office to insure that you are following proper procedures;

  4. Notify us of any delays or problems you encounter (contact Jay Alameda,, or any of the institutional contacts.)


We continue to monitor the developments and will consider any necessary options
