Subject: serverizing a fat process with named pipes
Date: Mon, 15 Jun 2009 23:17:00 -0400 [thread overview]
Message-ID: <7c737f300906152017m7776d596he8a1251c9e1279b8@mail.gmail.com> (raw)
I have a heavy process, an English parser loading megabytes of models,
and then reading stdin, sentence per line, outputting the parsed text
to the stdout. How do I properly serverize it -- running in the
background with <p1 >p2, those created with mkfifo p1 p2? Looks like
unless I wrap that in a kind of a loop, the processes exit at once.
First I did this simulation:
mkfifo p1 p1
cat <p1 >p2 &
cat p2 &
echo hi > p1
This does print "hi" and then both backgrounds exit. If I wrap them
in while true; do ... done & (& from the original goes outside), the
simple one looks running continuously, but the parser takes a while
starting up every time, apparently...
Cheers,
Alexy
