Trying to run HPL on markland cluster.
CPUs are E5-2670 which are supposedly ~155GFLOPS per socket. [1] Another source says 330 GFLOPS. [2] Let's be conservative and say 150GF per CPU. Trying one run of xhpl with gotoblas, I get about 26GFLOPS for one socket, or about one sixth of the max theoretical. Clearly not the best BLAS for this CPU.
