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
v=K*v
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.
Regards,
Sree
