CULA basic runtime error for QR, A MxN with M

Postby jrk1982 » Wed Aug 19, 2009 12:43 pm

Hello!

I tried to run the cula example, with M=100 and N = 1234. The qrf example exits with a runtime error.

I'm running this on a 32bit Linux computer, Fedora 10, with a GTX280, Cuda 2.3.

Works fine for 100x123. Not for 100x1234.

Good news! We were able to find and fix this bug. There is a very strong chance we'll have beta refresh and this change will most certainly be included in the update (and the final release, of course).

Thanks for the help!

JRK,
This should also be fixed in Beta 2.

Thanks,
John
