| 78 | PSSH |
| 79 | |
| 80 | -- Mainly for controlling large collections of nodes in the wide-area. |
| 81 | -- Has proven to be a better option for large coll of nodes like the Planet-Lab. I have contacted the developer asking for more info. |
| 82 | -- pscp,prsync,pnuke and pslurp are included in the pssh package. |
| 83 | |
| 84 | |
| 85 | GEXEC |
| 86 | |
| 87 | -- Faster |
| 88 | -- GEXEC operates by building an n-ary tree of TCP sockets and threads between gexec daemons and propagating control information up and down the tree. |
| 89 | -- By using hierarchical control, GEXEC distributes both the work and resource usage associated with massive amounts of parallelism across multiple |
| 90 | |
| 91 | nodes, thereby eliminating problems associated with single node resource limits (e.g., limits on the number of file descriptors on front-end nodes) |
