View Full Version : Mutexes, ssh and networking

October 5th, 2010, 12:38 PM
Hi all,

I am currently ssh'ing into another computer and want to have two programs running on different computers accessing the same piece of memory on the computer I am ssh'ing to. So I have been writing a program about mutexes, and it's taking a while because it's the first one I have ever written with mutexes, and I would like to know - will I be able to use mutexes across the network by different computers?

generic answer to this generic question:
yes when the the mutex you're using supports this kind of operation.

please describe more detailed what you want to do and which tools you are using.
Are you using a communication framework like MPI? (and no MPI does not have networked mutexes)
How do you expose the memory on the machine to the others?

maybe a simple lockfile on the shared machine is enough for your purpose.
