Version 3 of the various single priority array scheduler patches for 2.6.7, 2.6.8-rc2 and 2.6.8-rc2-mm1 kernels are now available for download and evaluation:
1. Standard O(1) scheduler with active/expired arrays replaced by a single array and an O(1) promotion mechanism plus scheduling statistics:
2.6.7 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.7-spa_trad_FULL-v3.0?download> 2.6.8-rc2 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc2-spa_trad_FULL-v3.0.1?download> 2.6.8-rc2-mm1 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc2_mm1-spa_trad_FULL-v3.0?download>
2. Basic O(1) scheduler with active/expired arrays replaced by a single array and an O(1) promotion mechanism plus scheduling statistics with all interactive bonus etc. removed:
2.6.7 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.7-spa_base_FULL-v3.0?download> 2.6.8-rc2 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc2-spa_base_FULL-v3.0.1?download> 2.6.8-rc2-mm1 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc2_mm1-spa_base_FULL-v3.0?download>
3. Priority based O(1) scheduler with active/expired arrays replaced by a single array and an O(1) promotion mechanism plus scheduling statistics with new interactive bonus mechanism and throughput bonus mechanism:
2.6.7 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.7-spa_pb_FULL-v3.0?download> 2.6.8-rc2 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc2-spa_pb_FULL-v3.0.1?download> 2.6.8-rc2-mm1 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc2_mm1-spa_pb_FULL-v3.0?download>
4. 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 interactive bonus mechanism and throughput bonus mechanism:
2.6.7 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.7-spa_zaphod_FULL-v3.0?download> 2.6.8-rc2 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc2-spa_zaphod_FULL-v3.0.1?download> 2.6.8-rc2-mm1 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc2_mm1-spa_zaphod_FULL-v3.0?download>
5. Slightly modified version of Con Kolivas's staircase O(1) 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-v3.0?download> 2.6.8-rc2 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc2-spa_sc_FULL-v3.0.1?download> 2.6.8-rc2-mm1 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc2_mm1-spa_sc_FULL-v3.0?download>
6. 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-v3.0?download> 2.6.8-rc2 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc2-spa_hydra_FULL-v3.0.1?download> 2.6.8-rc2-mm1 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc2_mm1-spa_hydra_FULL-v3.0?download>
7. Standard O(1) scheduler with scheduling statistics added:
2.6.7 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.7-stats-v3.0?download> 2.6.8-rc2 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc2-stats-v3.0.1?download> 2.6.8-rc2-mm1 <http://prdownloads.sourceforge.net/cpuse/patch-2.6.8-rc2_mm1-stats-v3.0?download>
