AVX2 Instruction Set Verification
On this page
SingleStoreDB can make use of AVX2 instructions on Intel and Intel-compatible processors, both for improved performance for columnstore query processing, and to enable use of certain vector functions.
If you want to verify if your system supports the AVX2 instruction set, check your processor specifications from the manufacturer or run
cat /proc/cpuinfo | grep avx2 to see if
avx2 (in lower case) is listed.
cpuinfo output but they still support AVX2.
check_ that is part of SingleStoreDB.
For example, to locate it, you can do:
cd / ; sudo find . -name check_avx2 -print
You may see output like:
The unique serial numbers and port numbers in this output may differ.
If it produces no output at all and does not produce an error, then the processor definitely supports AVX2.
