Unfortunately we don't currently have the time or resources to maintain a patch set for mongodb beyond simple compilation changes. Considering even the MongoDB dev team opted to let the compiler worry about SIMD optimizations instead of hand-writting them, our only options to provide dynamic AVX...
At the bottom of the valgrind output, we see the real problem is an invalid address: Address 0x18 is not stack'd, malloc'd or (recently) free'd Using gdb to analyze: Shows a segfault in MKL l9_commit commit function at instruction address 0x000000000962d1a9 use "disassemble...
In more simple words, AVX is a feature, called “instruction set” , that allows compatible processors to perform more demanding functions with compatible software.This instruction set is an Hardware feature: that means that it is not possible to perform an upgrade or an update to introduce this...

It is possible to make the 256-bit units warm up in advance by executing a dummy 256-bit instruction at a suitable time before the 256-bit unit is needed.The upper half of the 256-bit units will be turned off again after approximately 675 µs of no 256-bit instructions.This ...
before the ret instruction and everything works now. The remaining problem is: I don't really think this is a good solution because who knows where will the main function place my pointers next time I run the code? So guys, what do you usually do when you write s...
Since I am not sure which instruction to show the dump for I'll go through all 5 here (missing # 4 but it threw an error for that one not being able to find a function with that address): 1 ::Span<stream_executor::DeviceMemoryBase const>, xla::HloExecutionProfile*) () Dump of ...

On success, the error field is set to SUCCESS and the position field indicates either the number of code units validated for validation functions or the number of written code units in the output format for transcoding functions. In ASCII, Latin1 and UTF-8, code units occupy 8 bits (they ...
