Good stuff. Here's a little bit of shell that will go down that list
extracting the OS for each one:
for i in `wget -q -O - 'http://clusters.top500.org/db/result.php3?limit=100&Pro
cessor=%25&Country=%25&Interconnect=%25&order_type=desc&show%5B1%5D=site_name&s
how%5B2%5D=site_country&show%5B5%5D=System&show%5B6%5D=Integrator&show%5B7%5D=N
umber_node&show%5B8%5D=Processor_total&show%5B9%5D=Total_Peak_Performance&order
_field=Total_Peak_Performance&show%5B12%5D=Interconnect' | grep
'entry.php3?id=' | sed 's/^.*id=\([0-9]*\).*$/\1/'`; do wget -q -O -
http://clusters.top500.org/db/entry.php3?id=$i | awk '/Operating System/ {
os=1; next} { if(os == 1){print; exit} }' | sed 's/^.*\">\([^<]*\).*$/\1/';
done
The sort | uniq -c | sort -rn of the resulting list is:
87 Linux
4 Solaris
3 Tru64 UNIX
3
1 Windows NT
1 Linux Redhat
1 BSD
