The architecture also provides two supplementary memory types that are read-only and are accessible by all the threads: the constant memory and the texture memory. The lifetime of the global, constant and texture memory is the same with the kernel function's lifetime [13].
Unlike the strategy of thread-based task assignment proposed for aggregation and disaggregation at coarser level [16], we make a further step in data storage by using the four times larger texture memory in Kepler than Fermi.
More precisely, we load the terrain profile into the Compute Unified Device Architecture (CUDA) texture memory and parallelize the transmitter-receiver path profile computation.
Both constant and texture memory provide small on-chip caches that allow threads to take advantage of fine-grained spatial and temporal locality.
The implementation of the algorithm only considered the local memory of the threads and the global memory of the device; making use of other types of memory that offer GPU (shared memory, texture memory) and with a combination of them there could surely have been better results in a lesser number of iterations (executions).
Due to non-linear, tiled texture memory addressing (seehttp://www.x.org/wiki/Development/Documentation/HowVideoCardsWork/#index1h3), doing horizontal and vertical compute shader passes has essentially equal performance.
For example, global memory, constant memory, and texture memory are visible for both the parent and child grids and can be written within the parent and child grids coherently.
There are two additional read-only memory spaces accessible by all threads and constant and texture memory spaces (Figure 1).

CUDA threads can access data from different memory spaces on device, such as global, shared, constant, texture memory, and registers.
Therefore, it is not surprising that, after careful optimizations (e.g., to efficiently use GPUs' texture memory and improve data access locality) GPU ports of exact (5,6) or approximate (10) sequence alignment tools achieve significant speedups.
Topics covered include thread cooperation, texture memory, atomics and the use of CUDA C with multiple GPUs.
