Dear Xavier, Yes, I did. I followed the instructions available in that file, especially at sub-section 4.1.
I configured boot-strap IP using the ./configure options. in front-end node, the boot-strap IP is its IP address because I want to make it as an ftb_database_server. in every compute nodes, the boot-strap IP is the front-end's IP address. finally, I use default values for boot-strap port and agent-port. I asked MVAPICH authority about this issue along with process migration issue and they said it looks like the feature is broken and they will take a look at it in a low priority due to other on-going activities in the project. Thank you.
