I think we may have some significant resources here at the university level to tap into. I can imagine things like hosting a data mirror here if your pipeline offsite is not so big. Local IT folks seem to enjoy pushing limits and are always looking for customers. Our flagship research machine here, which is getting old by local standards, is a ~1000 node cray with 22,000 cores and a 5 PB high throughput work disk. Accounts are free to any researcher at the university - it is provided as a service. I'll certainly only be able to get a fraction of this, but a fraction may be significant on the scales of the types of problems we're working with.<br class=""><br class="">Matt<br class=""><br class="">---------------------------------------------------------------------<br class="">Matthew Shepherd, Associate Professor<br class="">Department of Physics, Indiana University, Swain West 265<br class="">727 East Third Street, Bloomington, IN 47405<br class=""><br class="">Office Phone: +1 812 856 5808<br class=""><br class=""><blockquote type="cite" class="">On May 16, 2016, at 10:34 PM, Chip Watson <<a href="mailto:watson@jlab.org" class="">watson@jlab.org</a>> wrote:<br class=""><br class="">All,<br class=""><br class="">Keep in mind that Scientific Computing is not provisioned to deliver that kind of bandwidth (500 MB/s) to you.
