[eigen] Using Eigen on SGI Altix uv 100

[ Thread Index | Date Index | More lists.tuxfamily.org/eigen Archives ]

Hi all,

I am using eigen on SGI Altix UV 100. 


My operations are very simple. I have  a vector "v" with a dimensionality of 1e6. I have to perform the operation


where K is a scalar constant. I may have to do this operation 1e5 times. 

Are there any special flags that I should use to improve the performance. For example, is it possible to increase speed by using openMP?

Any help will be greatly appreciated. Thanks very much.
