Re: Building MAGMA 1.3 on Mac OS X Mountain Lion
Posted: Thu Jan 17, 2013 6:49 pm
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|)
