AVX2 Instruction Set Verification

Verify AVX2 Support

A host’s support for the AVX2 instruction set can be verified in a number of ways:

• Checking the host's processor specifications from the manufacturer.

• Running either of the following on the command line and confirming that avx2 is listed.

  Shell

  Copy

  lscpu | grep avx2

  Shell

  Copy

  cat /proc/cpuinfo | grep avx2

• Deploying a new SingleStore cluster, where Toolbox automatically checks for avx2 support.

• Running check_avx2 from the singlestoredb-server-<version>-<hash>/lib directory on each host in an existing SingleStore cluster.

  AVX2 is supported if check_avx2 does not produce any output, does not produce an error, or does not fail.

  • Typical package-based deployment location

    • /opt/singlestoredb-server-<version>-<hash>/lib/check_avx2

  • Typical tarball-based deployment locations

    • /opt/singlestore/singlestoredb-server-<version>-<hash>/lib/check_avx2

    • /home/memsql/memsql/singlestoredb-server-<version>-<hash>/lib/check_avx2

  • You may also find the location of the singlestoredb-server-<version>-<hash> directory by viewing the process status of memsqld.

    Shell

    Copy

    ps -ef | grep memsqld

    /opt/singlestore/singlestoredb-server-<version>-<hash>/memsqld
