ECRC @ SIAM CSE21! Follow us @KAUST_ECRC

As in previous SIAM conferences on Parallel Processing (PP) and Computational Science and Engineering (CSE), ECRC members and their collaborators will have a strong presence at SIAM CSE21, nominally in Fort Worth, Texas, but held virtually due to the pandemic.

**************************************************

SIAM CSE21 will run virtually with live sessions.
