Sir;
i am beginning development of a CAD like program. it will be
threaded and multi-processor capable (well thanks to SMP O/S
like linux).
as to the linux's memory management, suppose a program has
30 threads. each thread is allocating and deallocating memory.
does linux block the other 29 threads when thread <X> wants
to malloc/free? how about other threads/processes in the process
table?
in a regular, single-processor system, my original C++ program
spent 50% of its time in malloc/free. i reduced this time very
significantly by implementing memory pools. the basic algorithm is fairly
easy to split up across threads. hence linux SMP for more performance.
but i am wondering if i might be walking into a "technical snare"
with respect to linux and memory management.
best regards,
Shane
