Hello, I have a very strange error happening that is driving me crazy.
I am able to compile and run fine the cuFFT sample in the PGI directory (with -Mcuda=4.0,cc20). However if I use setDevice to anything other than 0 (I have 2 C2050 and a Quadro NVS 290), I get the error
0: copyin Memcpy (dev=0x210300000, host=0x200300000, size=134217728) FAILED: 11(invalid argument)
when the memory is being copied from host to device (I am assuming). What is even more confusing is that if I compile with -Mcuda=3.2,cc20, selecting any of my devices works fine BUT the calculation of the FFT gives me highly inaccurate answers.
I am running Fedora 14, gcc 4.4.6 and PGI 11.6 compilers.
Thanks for anyones help :)
