Distributed computingΒΆ

Running populate on the same table on multiple computers, will causes them to attempt to compute the same data all at once. This will not corrupt the data since DataJoint will reject any dupilication. One solution could be to cause the different computing nodes to populate the tables in random order. This would reduce some collisions but not completely prevent them.

To allow efficient distributed computing, DataJoint provides a built-in job reservation process.

matlab In MATLAB, job reservations are activated by replacing populate calls with identical parpopulate calls.

python In Python, job reservations are activated by setting the keyword argument reserve_jobs=True in populate calls.
