It provides a set of simulatedprocessors that run standard Unix executable files compiled fora MIPS R3000 based multiprocessor. These generate multiplestreams of memory reference events that drive a user-providedmemory system simulator. MINT uses a novel hybrid techniquethat exploits the best aspects of native execution and softwareinterpretation to minimize the overhead of processor simulation.Combined with related techniques to improve performance, thisapproach makes simulation on uniprocessor hosts extremely efficient.<P>Mint is available without charge to academic and research sites.<P><UL><LI> <!WA13><a HREF="ftp://ftp.cs.rochester.edu/pub/packages/mint/mint.README">README file</a><LI> <!WA14><a HREF="ftp://ftp.cs.rochester.edu/pub/packages/mint/mint.user.manual.ps.Z">MINT Tutorial and User Manual</a><LI> <!WA15><a HREF="ftp://ftp.cs.rochester.edu/pub/papers/systems/94.MASCOTS.MINT:Efficient_simulation_of_shared-memory_multiprocessors.ps.Z">MACSOTS '94 paper</a><LI> <!WA16><a HREF="ftp://ftp.cs.rochester.edu/pub/packages/mint/mint.tar.Z">Compressed source code (tar format)</a></UL><HR><!WA17><A HREF="http://ftp.arpa.mil/Summaries/Rochester--LeBlanc--Locality_Management.html"> <!WA18><IMG ALIGN=MIDDLE SRC="http://www.cs.rochester.edu/images/forward.gif"> ARPA project page</A><P> <ADDRESS>Last Change: 1 March 1995 / scott@cs.rochester.edu</ADDRESS></BODY></HTML>?? 快捷鍵說明
