turf's Issues

MIPS architecture support

Hi Jeff,
this repository is awesome, thank you!

there is ARM and X86_64 support in turf/c/impl/, MIPS support is also something that would be nice to have.
I'm not sure if raising an issue would be the right way to start the discussion, please feel free to close the issue if you don't plan/want to add MIPS support in the future.

Thanks!

Turf does not support Android

turf/impl/Affinity_Linux.cpp:62:14: error: use of undeclared identifier 'pthread_setaffinity_np'; did you mean 'sched_setaffinity'?

Clang build support?

Any plans to also support a recent version of clang on linux in addition to gcc?

Thanks for your excellent blog articles and libs.

RecursiveMutexTester deadlock

When running with boost through visual studio, RecursiveMutexTester does not exit. I assume there is a deadlock.

REPRO:

Generate with:
cmake -DTURF_WITH_BOOST=TRUE -DTURF_PREFER_BOOST=TRUE -DBoost_USE_STATIC_LIBS=ON -DBOOST_ROOT=D:/boost_1_60_0 -DBOOST_INCLUDEDIR=D:/boost_1_60_0/boost -DBOOST_LIBRARYDIR=D:/boost_1_60_0/lib64-msvc-14.0 -G "Visual Studio 14 2015 Win64" ..
Build and run SynchroTests.

Intel tbb win support

Recently found that visual studio 2015 benefitted significantly from using the tbb malloc alternative.

Any support likely in turf?

The TL:DR bit

Other allocators claiming good multithread performance did not scale well with modest numbers of threads.
E.g 4 cores each with 10m individually heap allocated 450 byte objects.
Simultaneous map resets took 8 sec per core and 9 secs wall clock time.

Alternative allocators below had some variation but typically became so bad the best of the others was 11sec one core, 50 sec to complete four cores. Serialised and extra lock contention.

Note the test is not a great design and should be using pool allocation but it illustrates the huge differences in windows multithreaded allocator support.

I cant vouch for the rest of tbb but the allocator scaled well when tcmalloc jemalloc and hoard all failed to scale in vs2015.
I suspect the others lag behind because they may not yet implement the latest hooks needed in the new crt.
