A Tool for Binding Threads to Processors
Responsible organisation
2001 (English)Conference paper, (Refereed) Published
Abstract [en]

Many multiprocessor systems are based on distributed shared memory. It is often important to statically bind threads to processors in order to avoid remote memory access, due to performance. Finding a good allocation takes long time and it is hard to know when to stop searching for a better one. It is sometimes impossible to run the application on the target machine. The developer needs a tool that finds the good allocations without the target multiprocessor. We present a tool that uses a greedy algorithm and produces allocations that are more than 40% faster (in average) than when using a binpacking algorithm. The number of allocations to be evaluated can be reduced by 38% with a 2% performance loss. Finally, an algorithm is proposed that is promising in avoiding local maxima.
