For a system with 4 AMPs, you create a database with 1 gigabyte of temporary space. The per-AMP quota of temporary space is 250 megabytes. If you set the temporary skew limit to 20%, any AMP is allowed a skew limit of 50MB above the per-AMP quota of temporary space. An AMP can use up to 300 megabytes of temporary space as long as total temporary space used does not exceed the 1 gigabyte global limit for temporary space.
