Hello,
I am running a calculation using the mkl pardiso solver (vs 10.2.2.025). I have built this console app for ia32 and x64 windows, both run on 64 bit xp. For solves on a problem with about 20,000 equations, the solution time between ia32 and x64 is negligible. For higher order problems with about 60,000 equations, the ia32 app runs about 3 time slower than the x64 app (97 vs 32 seconds).
For my requirements, this is much too slow. Is there some kind of 'tweak' on pardiso that will help me get the performance I need on ia32 ?
Thanks in advance,
John McElhaney

Hi,
Could you provide us statistical output of running testcases with 60000 equation (setting msglvl=1)? If outputs are simmilar it would be nice if send testcase with you matrix to us.
With best regards,
Alexander Kalinkin
