I am learning parallel computing tool box in MATLAB. My CPU is Intel Core 2 Duo T 6400 2.00 Ghz and MATLAB R2009a. I executed two program one is sequential and another is parallel using SPMD command but i found
The spmd statement can be used only if you have Parallel Computing Toolbox™. To execute the statements in parallel, you must first create a pool of MATLAB workers using parpool or have your parallel preferences allow the automatic start of a pool. Inside the body of the spmd statement, ...
On the other hand, most of the existing approaches to performance debugging are very general and thus do not provide the user feedback in terms of the high level programming model or the source code of the parallel application. In this paper, we describe a novel approach to performance ...
To create a parallel pool, useparpool. To use a subset of an existing pool, usepartition. Tips Anspmdblock runs on the workers of the existing parallel pool. If no pool exists,spmdwill start a new parallel pool, unless the automatic starting of pools is disabled in your parallel settings...

Single Program, Multiple Data (SPMD) is a parallelization technique in computing that is employed to achieve faster results by splitting the program into multiple subsets and running them simultaneously on multiple processors/machines.

The emergence and widespread adoption of the single program, multiple data (SPMD) programming model and the standardization of parallel communications libraries in the 1990s have increased the use of parallel computers and offered the carrot of the very highest performance for scientific computing. Accel...
In order to adapt SIMD machine to more flexible SPMD paradigm for MIMD machine, a new branching mechanism is introduced.doi:10.1016/S0927-5452(98)80023-3Yoshizo Takahashi aMasahiko Sano aTornio Inoue aAdvances in Parallel Computing
