 Please use one of the following targets:
 
 	alpha
 	alpha-mpich
 	linux-lam
 	linux-mpich
 	linux-opteron-mpich-acml
 	ia64-mpich-ecc

 	t3e
 	reconfig (to bring this menu up again)
 
 After configuration, please check the VBLASLIB variable in 
 sys.def and make sure that it is pointing to the vendor BLAS
 library if one exists.

Pilih target yang benar, misalnya 

 make linux-mpich

Akan keluar

 ln -s conf/sys.linux-mpich sys.def

Kita bisa lihat opsi compile yang dipilih melalui perintah

 vi sys.def

==Jalankan Benchmark==


Build benchmark:

 make

akan keluar

 Please use one of the following targets:
 
 For all three : compile, run, script, graph, clean, clobber, reconfig
 For BlasBench : blas-bench, blas-run, blas-script, blas-graph
 For CacheBench: cache-bench, cache-run, cache-script, cache-graph
 For MPBench   : mp-bench, mp-run, mp-script, mp-graph
 
 clean: removes object files and leaves result files
 clobber: removes binary files and leaves result files
 distclean: removes everything!

yang jalan tampaknya hanya cachebench, lakukan 

 make cache-bench
 make cache-run
 make cache-script
 make cache-graph
 chmod -Rf 777 results
 chown -Rf nobody.nogroup results
 cd results
 ps2pdf namafile.ps namafile.pdf
