[Apologies if you got multiple copies of this email.] *1st Future of MPI RMA Workshop (FoRMA'22)* https://mpiwg-rma.github.io/forma22/ The MPI RMA Working Group is organizing a workshop aimed at gathering inputs from users and implementors of MPI RMA with past experiences and ideas for improvements, as well as hardware vendors to discuss future developments of high-performance network hardware relevant to MPI RMA. The goal is to evaluate the current design of MPI RMA, to learn from the current state of practice, and to start the process of rethinking the design of one-sided communication in the MPI standard. The workshop will be held entirely virtual on *June 16 & 17* and the results and contributions will be combined into a joint white paper. *Call for Short Talks* We are seeking input from users of MPI RMA willing to share their experiences, results, and lessons learned in short talks of 10-15 minutes. No stand-alone publications are required. In particular, the following topics for contributions are of interest: - Successful and unsuccessful attempts of using MPI RMA to improve the communication efficiency of applications and middle-ware; - Challenges in implementing and porting applications and middle-ware on top of MPI RMA; - Features that are missing from MPI RMA. If interested, please send a short email with the title of the talk [email protected]. *Call for Participation* We encourage everyone interested in one-sided communication models in general and MPI RMA in particular to join this two day workshop and contribute to its success through questions and comments. We encourage a lively and open exchange of ideas and discussions between the speakers and the audience. The connections information will be posted before the workshop athttps://mpiwg-rma.github.io/forma22/. Please direct any questions [email protected]. *Registration* To register for the workshop (and receive the access link) please use the registration site at https://tennessee.zoom.us/meeting/register/tJ0qduChrDgsGNdEG3MQeLB-DH3lZ6r-D....
