# qatmgr(8)

QAT resource manager qatmgr

## NAME

qatmgr - QAT resource manager

**qatmgr**

## SYNOPSIS

**qatmgr** \[option\]...

## DESCRIPTION

**qatmgr** is a daemon that manages QAT resources for the Intel© Quick Assist Technology (Intel© QAT) user space library (qatlib).

## OPTIONS

- **-d**, **--debug=LEVEL**

  set debug level, default 0 for no debug. Higher debug level produces more output.

- **-f**, **--foreground**

  run in the foreground. By default, the qatmgr runs as a daemon in the background.

- **-h**, **--help**

  display help page

- **-p**, **--policy=POLICY**

  selects the QAT manager policy. This determines how resources should be allocated to each process using the qatlib library. The default POLICY 0 allocates one virtual function (VF) from each physical function (PF) endpoint to each process. This should be selected for best performance. A POLICY of 1 allocates a single VF to each process. This should be selected for maximum scalability. Any other POLICY value allocates that number of VFs to each process.
