Looks good, thanks for the help!

Code: Select all
testing$ ./testing_sgetrf -c -l
MAGMA 1.3.0
device 0: GeForce GT 330M, 1100.0 MHz clock, 255.7 MB memory, capability 1.2

Usage: ./testing_sgetrf -N <m,n> -c -c2 -l
  -N  can be repeated up to 10 times. If only m is given, then m=n.
  -c  or setting $MAGMA_TESTINGS_CHECK checks result, PA - LU.
  -c2 for square matrices, solves one RHS and checks residual, Ax - b.
  -l  or setting $MAGMA_RUN_LAPACK runs LAPACK.

    M     N   CPU GFlop/s (sec)   GPU GFlop/s (sec)   |PA-LU|/(N*|A|)

Hmm... the error is wrong there. It should be around 1e-08 or 1e-09, but some are getting only 1e-03. If I get a chance, I'll try to compile it and run some tests here.
