UnixBench
Untuk melakukan benchmarking kemampuan komputasi komputer yang kita gunakan. Ada banyak test yang dilakukan oleh UnixBench yang lumayan memusingkan untuk di bahas dalam waktu yang singkat. Yang menarik UnixBench akan pada akhirnya memberikan Final Score dari komputer yang kita evaluasi / benchmarking. Hanya saja tampaknya UnixBench ini belum memanfaatkan secara penuh kemampuan multiprocessor yang ada di sebuah mesin. Jadi untuk sebuah mesin Xeon Quad, maka score UnixBench mungkin perlu dikalikan dengan jumlah processor yang ada, karena memang unixbench belum memanfaatkan penuh multiprocessor yang ada.
Dari hasil evaluasi yang ada tampak bahwa score UnixBench untuk masing-masing processor berikut adalah,
Intel Pentium III 179.6 Axioo Seri N Centrino Duo 687.1 Rainer Server Xeon Quad 867.0 (perlu di kali 4)
Instalasi
apt-get install x11proto-xext-dev x-dev libx11-xcb-dev
Download
http://byte-unixbench.googlecode.com/files/unixbench-5.1.2.tar.gz
cp unixbench-5.1.2.tar.gz /usr/local/src/ cd /usr/local/src/ tar zxvf unixbench-5.1.2.tar.gz cd /usr/local/src/unixbench-5.1.2
Entah kenapa -lXext tidak tersedia di Ubuntu source Makefile perlu di edit
cd /usr/local/src/unixbench-5.1.2 vi Makefile
pastikan
# Set "GL_LIBS" to the libraries needed to link a GL program. # GL_LIBS = -lGL -lXext -lX11 GL_LIBS = -lGL -lX11
Lanjutkan ..
cd /usr/local/src/unixbench-5.1.2 make ./Run
Detail Proses Evaluasi
Detail proses evaluasi oleh UnixBench tampak pada cuplikan di bawah ini. Pada dasarnya yang perlu kita lakukan hanya (1) membuka file tar, dan (2) menjalankan ./Run dari folder UnixBench. Tampilannya adalah sebagai berikut,
make all
make[1]: Entering directory `/usr/local/src/unixbench-4.1.0'
Checking distribution of files
./pgms exists
./src exists
./testdir exists
./tmp exists
./results exists
make[1]: Leaving directory `/usr/local/src/unixbench-4.1.0'
