In order to improve the software performance for a CUDA developed application, the programmers must optimize the number of active threads and to balance their memory resources: the number of registers and threads used per multiprocessor
, the global memory bandwidth and the percentage of memory allocated to each thread.

In Section 4, we originate the hardware details of multiprocessor
systems and Section 5 deliberates real-time simulator model.
We are considering the mapping of tasks onto a multiprocessor
system and it consists of n identical processors P.

In shared-memory multiprocessors
with private caches, large cache blocks may also cause false sharing [Lilja 1993], which occurs when two or more processors wish to access different words within the same cache block and at least one of the accesses is a store.
capabilities on our high-end HP 9000 technical servers, combined with paralleled industry-leading software applications, provide chemists with unequalled computing resources."
Coping with memory latency is a fundamental challenge in large-scale shared-memory multiprocessors
. Part of the problem is the ever-widening gap between processor and memory speeds--a technology trend that is expected to continue.
Parallel, concurrent, and distributed programming required new ways to mediate access to hardware, for example user-level threads were devised to ameliorate the problems of programming multiprocessor
This design has been used in mainframe multiprocessors
for something like two decades.
