NT-MPICH Performance

We compared the performance of the following MPI implementations for Microsoft Windows NT/2k/XP:

• NT-MPICH, the Windows part of our MP-MPICH,
• MPICH.NT 1.2.5, the Windows version of MPICH by ANL/MSU,
• MPI/Pro 1.6.4.1 for Windows by Verari Systems Software (formerly MPI Software Technology),
• WMPI II 2.4.0 by Critical Software.

Adding to that, we compared the performance of different kinds of interconnections, namely:

• Fast Ethernet (100 MBit/s)
• Gigabit Ethernet (1000 MBit/s)
• SCI
• Shared Memory

We used the following benchmarks:
