Subject: [PATCH] V-4.1 Single Priority Array O(1) CPU Scheduler Evaluation
Date: Thu, 12 Aug 2004 15:59:15 +1000 [thread overview]
Message-ID: <411B0733.5080505@bigpond.net.au> (raw)
Version 4.1 of the various single priority array scheduler patches for
2.6.7 and 2.6.8-rc4 kernels are now available for evaluation.
This version contains a fix for a bug causing excessive promotion and an
update of the staircase scheduler code to match Con's 7.I version.
1. [ZAPHOD] My proposed replacement scheduler which offers runtime
selectable choice between a priority based or entitlement based O(1)
scheduler with active/expired arrays replaced by a single array and an
O(1) promotion mechanism plus scheduling statistics with new simplified
interactive bonus mechanism and throughput bonus mechanism:
2.6.7
<http://prdownloads.sourceforge.net/cpuse/patch-2.6.7-spa_zaphod_FULL-v4.1?download>
and/or
<http://prdownloads.sourceforge.net/cpuse/patch-2.6.7-spa_zaphod-v4.0-to-v4.1?download>
2.6.8-rc4
<http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc4-spa_zaphod_FULL-v4.1?download>
2. [SC] Slightly modified version of Con Kolivas's staircase O(1)
(version 7.I) scheduler with active/expired arrays replaced by a single
array and an O(1)promotion mechanism:
2.6.7<http://prdownloads.sourceforge.net/cpuse/patch-2.6.7-spa_sc_FULL-v4.1?download>
and/or
<http://prdownloads.sourceforge.net/cpuse/patch-2.6.7-spa_sc-v4.0-to-v4.1?download>
2.6.8-rc4
<http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc4-spa_sc_FULL-v4.1?download>
3. [HYDRA] Runtime selection between staircase, priority based and
entitlement based O(1) schedulers:
2.6.7
<http://prdownloads.sourceforge.net/cpuse/patch-2.6.7-spa_hydra_FULL-v4.1?download>
and/or
<http://prdownloads.sourceforge.net/cpuse/patch-2.6.7-spa_hydra-v4.0-to-v4.1?download>
2.6.8-rc3
<http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc4-spa_hydra_FULL-v4.1?download>
Other schedulers are also available from
