Board reporting change

2015-07-29 Thread Patricia Shanahan
August is a board report month for River. There will be slight change in procedure. The board is concerned about projects whose reports do not change much from month-to-month. That can mean a healthy project that is just progressing slowly, but has a functional PMC etc. I believe that is the

Re: tree-based / log(p) communication cost algorithms for River?

2015-07-29 Thread Greg Trasuk
I’ve wondered about doing this in the past, but for the workloads I’ve worked with, I/O time has been relatively low compared to processing time. I’d guess there’s some combination of message frequency, cluster size and message size that makes it compelling. The idea is interesting, though,

tree-based / log(p) communication cost algorithms for River?

2015-07-29 Thread Bryan Thompson
Hello, I am wondering if anyone has looked into creating tree based algorithms for multi-cast of RMI messages for river. Assuming a local cluster, such patterns generally have log(p) cost for a cluster with p nodes. For the curious, this is how many MPI messages are communicated under the hood.
