Use of multiprocessors

CYPECAD and Metal 3D use, during the analysis process, the potential offered by multiprocessors.

To acquire these benefits, there are two modules available which allow the user to make the most of the yield advantages of the multiprocessors:

• Parallel analysis with two multiprocessors
• Parallel analysis with four multiprocessors

Using computers with two or four parallel processors (Dual core and Quad core) together with the corresponding module, a substantial amount of time can be saved in the analysis process with CYPECAD and Metal 3D. In Metal 3D, the time taken to redesign the section is also significantly reduced with the use of these modules in computers with multiprocessors.

The time taken to analyse a structure does not only depend on what type of processor the computer has installed (multiprocessor or monoprocessor), other factors also intervene, such as the hardware installed on the computer, the operating system and, of course, the structure being analysed (type of floor slab introduced, presence of walls, volume of the structure to analyse, etc).

To test the yield rate of the two analysis using multiprocessors modules, we at CYPE, have carried out several comparative studies using a computer with two multiprocessors and another with four. Several jobs have been analysed in both computers using the corresponding module and without it. 

Comparative study:

The table below provides a summary of the properties of 4 jobs that were analysed and the respective time reductions in the analysis when the modules were used:

Job description		Job Number
		1	2	3	4
Number of floors		6	4	6	27
Floor slab surface areas m2	Waffle slab	5 822	4 951		23 579
	Flat slab	2 181		32 432	3 713
	Mat foundation		1 911		1 255
	Total	8 003	6 862	32 432	28 547
Wall lateral surface area m2		1 017	1 093	11 021	2 342
Applied loads		wind & seismic	wind & seismic	wind & seismic	wind & seismic
Analysis with 2 multiprocessors	WITH module	6H 33'	1H 19'	6H 11'	3H 56'
	WITHOUT module	11H 54'	2H 20'	10H 32'	6H 25'
	Time saved	45%	43%	41%	39%
Analysis with 4 multiprocessors	WITH module	3H 6'	41'	3H 23'	2H 21'
	WITHOUT module	9H 17'	1H 51'	8H 27'	5 H 18'
	Time saved	67%	63%	60%	56%

 

The time saved in analysing the structure is multiplied bearing in mind that a single structure may have to be analysed several times until its optimum design is reached.

In these comparatives, for each test, the only factor that was varied was the use of the Analysis with multiprocessors module.
