Mixed Uni-Processor and SMP Cluster Nodes

The Scyld ClusterWare system architecture eliminates the problem of unintentionally running different versions of a program over the cluster's compute nodes.

The cluster nodes are required to run the same kernel version, typically with the same features and optimization enabled. Uni-processor machines can run the SMP kernel. The best choice for a mixed cluster is to run the SMP kernel. Beginning with CW4.1.1, support for uniprocessor kernels was dropped.
