Short Explanation

Nowadays, the computational systems (multi and uniprocessors) need to avoid the cachecoherence problem. There are some techniques to solve this problem. The MESI cachecoherence protocol is one of them. This paper presents a simulator of the MESI protocolwhich is used for teaching the cache memory coherence on the computer systems withhierarchical memory system and for explaining the process of the cache memory location inmultilevel cache memory systems. The paper shows a description of the course in which thesimulator is used, a short explanation about the MESI protocol and how the simulatorworks. Then, some experimental results in a real teaching environment are described.

The Right

Abstract The target article carefully describes the memory system, centered on the temporal lobe that builds specific memory traces. It does not, however, mention the laterality effects that exist within this system. This commentary briefly surveys evidence showing that clear asymmetries exist within the temporal lobe structures subserving the core system and that the right temporal structures mainly underpin face familiarity feelings.
