The time to access shared memory is the same in the Uniform Memory Access (UMA) shared memory multiprocessor model.

Here's why:

1. In a UMA model, all processors share the physical memory uniformly. The access time to a memory location is the same for all processors, hence the name Uniform Memory Access.

2. In contrast, Non-Uniform Memory Access (NUMA) systems have variable access time depending on the memory location. The memory is divided among the various processors, and while a processor can access all the memory, it accesses the memory it owns faster than the memory owned by other processors.

3. Cache Only Memory Architecture (COMA) is a type of shared memory implementation where the main memory is basically a cache. It also does not guarantee uniform access times.

4. Cache Coherent Non-Uniform Memory Access (ccNUMA) is a type of NUMA architecture that includes a cache coherency protocol, ensuring that changes in the values of shared operands are propagated throughout the system in a timely manner. It also does not provide uniform access times.

So, the answer is UMA.
