A significant fraction of the xGPU library and the mwax_db2correlate2db process is written in CUDA, so a CUDA-compatible GPU is essential.

The MWAX correlator uses, and has tested, this commit (ca505cdb519afbd63ae91c00e4d86af0f3313b68) from the PSRDADA repository.
For Ubuntu 20.04 systems, the following packages also need to be installed in order to compile PSRDADA successfully (this was discovered through trial and error) - other Debian based systems should have similar requirements:

$ sudo apt update $ sudo apt install automake autoconf csh hwloc libhwloc-dev libhwloc-plugins libtool numactl pkg-config python2.7-dev python |
This is how we build it (note: some paths may be different on your system):

| Key | Existing Value | Set To | Notes |
|---|---|---|---|
| MODE | MWAX_VCS | MWAX_CORRELATOR | Required |
| INT_TIME_MSEC | a default set by the M&C system | 250-8000 | This is the correlator integration time (in ms) |
| FSCRUNCH_FACTOR | a default set by the M&C system | 1-6400 | The number of 200 Hz ultrafine channels to scrunch together into a fine channel. E.g. for 10 kHz fine channels set this to 50 |
| FINE_CHAN_WIDTH_HZ | a default set by the M&C system | 200-1280 | Redundant info but must be compatible with the FSCRUNCH_FACTOR. E.g. 10000 for 10kHz fine channel width |
| NFINE_CHAN | a default set by the M&C system | 1-6400 | Redundant info but must be compatible with FSCRUNCH_FACTOR and FINE_CHAN_WIDTH_HZ. E.g. 128 for 10kHz fine channels |
