Is .NET/Mono or Java the better choice for cross-platform development? [closed]

What is the meaning of “non temporal” memory accesses in x86
... Intel Streaming SIMD Extensions (Intel SSE)" chapter:
Caching of Temporal vs. Non-Temporal Data
Data referenced by a program can be temporal (data will be used again) or non-temporal (data will be referenced once and not reused in the immediate future). For example, program code is generally tempo...
