The CFD code Overflow includes as one of its solver options a quasi-SSOR algorithm. This is a fairly small piece of code but it accounts for a significant portion of the total computational time. This paper studies some of the issues in accelerating the code by use of a GPU. The algorithm needs to be modified to be suitable for a GPU, and attention needs to be given to 64-bit and 32-bit arithmetic.
