nazdar,<br><br>mne sa nejak nepozdava ten tvoj zapis &#39;nice make -j20&#39;. Aky level si zadal pri nice? Volba -j20 neznamena nahodou, ze mas 20 (-1) procesorov, resp. kompilacia ma byt optimalizovana na taky pocet procesorov?
<br>Ja mam v make.conf nastavene premenne takto:<br>MAKEOPTS=&quot;-j2&quot;<br>PORTAGE_NICENESS=&quot;15&quot;<br><br>mam notebook s P-M 1,6 GHZ a nikdy pri kompilacii nemam problem s odozvou systemu, ani ked nastavim taktovaciu frekvenciu na 800MHz (aby sa moc neprehrieval).
<br><br>s pozdravom<br><br>Tomas Jankovic<br><br><div><span class="gmail_quote">2007/6/24, Jan Kundrát &lt;<a href="mailto:jkt@g.o">jkt@g.o</a>&gt;:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Zdravim,<br>mam pocitac s dual core CPU a 1GB pameti, bez swapu. Pustil jsem variaci<br>na `nice make -j20`, bylo co kompilovat, stroj to vydrzel asi pul<br>minuty, pak mi prestaly odpovidat Xka (driver fglrx). Load byl okolo 8,
<br>mozna 9 (posledni viditelny udaj z topu). Kompilace bezela na XFS<br>filesystemu, jadro je 2.6.21-gentoo, preemptivni, tickless. LEDka od<br>disku blikala jako diva, bylo slyset seekovani.<br><br>Myslim si, ze kdyz neni rozdil mezi `make` a `nice make` a oboji stroj
<br>efektivne shodi (nulovou reakci na CapsLock, pohyb mysi, Ctrl+Alt+Fx,<br>Ctrl+Alt+Backspace pokladam za znamku mrtveho stroje), je neco shnileho<br>ve stroji cinskem.<br><br>Taky me zarazilo, ze pri jednom z pokusu stihnul Amarok bez kakychkoli
<br>problemu dohrat aktualne pustenou pisnicku. Byla dlouha, do bufferu<br>zvukovky se IMHO nemohla vejit, nebo toho hda_intela hodne podcenuju.<br>Zrejme prehrava s realtime prioritou.<br><br>Nevite nekdo, co s tim? Stacilo by mi zachovat aspon nejakou rozumnou
<br>odezvu Xek, tedy mit moznost se prepnout do meho oblibeneho terminalu a<br>killnout danou ulohu.<br><br>Hezky vecer,<br>-jkt<br><br>--<br>cd /local/pub &amp;&amp; more beer &gt; /dev/mouth<br><br><br></blockquote></div>
