# AVX2 Instruction Set Verification SingleStore can take advantage of the [AVX2 instruction set](https://en.wikipedia.org/wiki/Advanced_Vector_Extensions) on Intel and Intel-compatible processors to improve the performance of [columnstore query processing](https://docs.singlestore.com/db/v9.1/create-a-database/columnstore.md) and enable the use of certain [vector functions](https://docs.singlestore.com/db/v9.1/reference/sql-reference/vector-functions/using-vector-functions.md). ## 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 lscpu | grep avx2 ``` ```shell cat /proc/cpuinfo | grep avx2 ``` * Deploying a new SingleStore cluster, where Toolbox [automatically checks](https://docs.singlestore.com/db/v9.1/reference/configuration-reference/cluster-configuration/system-requirements-and-recommendations.md) for `avx2` support. * Running `check_avx2` from the `singlestoredb-server--/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--/lib/check_avx2` * Typical tarball-based deployment locations * `/opt/singlestore/singlestoredb-server--/lib/check_avx2` * `/home/memsql/memsql/singlestoredb-server--/lib/check_avx2` * You may also find the location of the `singlestoredb-server--` directory by viewing the process status of `memsqld`. ```shell ps -ef | grep memsqld ``` ```output /opt/singlestore/singlestoredb-server--/memsqld ``` *** Modified at: April 12, 2024 Source: [/db/v9.1/reference/configuration-reference/cluster-configuration/avx-2-instruction-set-verification/](https://docs.singlestore.com/db/v9.1/reference/configuration-reference/cluster-configuration/avx-2-instruction-set-verification/) (An index of the documentation is available at /llms.txt)
