The LDRD Prime call in Advanced Computing is at http://web.anl.gov/LDRD/new-ldrd/index.html. Pre-proposals (1-2 pages, following a template) are due May 9. The list of topics is attached below. Note that the separate X-ray sciences call highlights that anyone with a proposal on deep learning, data analytics, or visualization should submit to the CELS LDRD call. Please let me know if you have any questions. Regards — Ian
