 In Generation 1 of Caviness two types of node were offered to stakeholders:  traditional compute and GPU-enhanced compute nodes.  Each type was upgradeable (at purchase) to memory sizes above the baseline 128 GB.  Based on feedback from stakeholders, Generation 2 of Caviness will offer one new type of node and will expand the GPU-enhanced type into three variants. In Generation 1 of Caviness two types of node were offered to stakeholders:  traditional compute and GPU-enhanced compute nodes.  Each type was upgradeable (at purchase) to memory sizes above the baseline 128 GB.  Based on feedback from stakeholders, Generation 2 of Caviness will offer one new type of node and will expand the GPU-enhanced type into three variants.
