Hello,
I wonder if it is considered to be a
multiprocessor-system in linux if you install linux on two pc's
and connect them with ethernet or a bus
?
If it is, how do you synchronize access to a
memoryunit also connected with the two pc's with
semaphores ? Does this type of programming lie
within linux ?
If it isn't I suppose you could solve it
something like this:
I guess you cannot have the code for
the semaphore compiled on the memoryunit
since the two pc's may have
different hardware-structures. So, instead I believe you can have
a memoryaddress on the memoryunit to
protect some codearea. The address initially set to
1 and decreased when one pc wants to access the codearea and set
back to 1 when finished.
regards,
Magnus
