Dear,
I would like to put a buffer `shared(char[])` into a shared
memory ( L2 cache ) and provide a start and end index to multiple
thread in order to perform computation on a piece of original
buffer.
I read doc from std.concurrency, std.parallelism, core.thead
(druntime) and vectorization (simd) . But I found any example or
unittest which perform such calculus.
1/ So did you have an example somewhere ?
2/ about shared keyword do we ensure that its size is lower than
L2 or L3 cache using :
```
core.sys.posix.unistd: sysconf, _SC_LEVEL2_CACHE_SIZE,
_SC_LEVEL3_CACHE_SIZE;
immutable size_t L2_CACHE_SIZE = cast(size_t)
sysconf(_SC_LEVEL2_CACHE_SIZE);
immutable size_t L3_CACHE_SIZE = cast(size_t)
sysconf(_SC_LEVEL3_CACHE_SIZE);
```
3/ variable flagged as `shared` does at mean the variable is put
into L2 cache ?
thanks for your help
best regards
