Space effective compute node

Semakin hari, semakin efisien penggunaan space server yang dapat dimasukkan ke dalam rack data center.

waktu yang lalu telah mencoba technology 1U twin dari supermicro, dimana dalam 1U rackmount server terdapat 2 buah serverboard dengan kemampuan dapat menampung 2 buah processor Xeon Quad Core dan 48GB memori. cukup dengan power 780watt. ckckck …. so far .. no complain about 22 node of these type of server.

1U Twin

baru-baru ini supermicro mengeluarkan series baru 2U twin2.. dashyat… 2U = 4x serverboard = 4 x 2 processor Quad core = 4 x 48GB memori.cukup dengan power 1000watt. wuih … a lot of number .. i wish i could try this machine …

perl : memotong segy file per FFID/fldr

SU Unix is powerful tools to process segy data.

#!/usr/bin/perl

sub trim {
my $string = shift;
for ($string) {
s/^\s+//;
s/\s+$//;
}
return $string;
}

# convert to SU file
#system(’segyread tape=data.sgy endian=0 verbose=1 | segyclean > data.su’);
# reading header file
#system(’sugethw < data.su key=fldr > data.hdr’);

#loop to write
open(FILE,”data.hdr”) || die “cannot open file”;
$prevdata = ‘www’;
while(<FILE>)
{
$info = $_;
#print $info;
# parse info
$key = ‘none’;
($key,$val)=split(‘=’,$info);
#print(‘*’,trim($key),’*',$val,’*');
$key = trim($key);
$val = trim($val);
print(“*$key*$val* \n”);
if ($key eq “fldr”) {
if ($val ne  $prevdata) {
system(“suwind key=fldr min=$val max=$val < data.su  > $val.su”);
system(“segyhdrs < $val.su”);
system(“segywrite tape=$val.segy endian=0 verbose=1 < $val.su”);
$prevdata=$val;
}else{
#skip
print(“—>skipped already process : $val \n”);
}
}else{
#skip
print(“–>skipped empty \n”);
}

}
close(FILE);
#end loop

have a nice try!

fiuhhh … capeknya …

setelah menginstall :
centos 4.7 –> gagal (VGA display amburadul)
centos 5.2 x86_64 –> gagal (ternyata source installernya 32bit)
FC9 i386 –> gagal (banyak library tidak compatible)
suse 11 –> gagal (tidak bisa buka segy cd)
