v20 v21 161 161 Summary of overall results: 162 162 163 * ''To be added once the baseline finishes.'' 163 * We switched back to a variation of an earlier logging method, which worked better. 164 * We switched to running 'screen' on each MyPLC plnode, to deal with the problem of losing connections to the plnodes. 165 * We accidentally failed to actually send 10 Mb/s on the ping and UDP slices. 166 * Other things went smoothly, providing a good basis for Baseline 6. 164 167 165 168 For more details, see the [wiki:PlasticSlices/BaselineEvaluation/Baseline5Details Baseline 5 Details] page. For an overview of slices, participants and experiments, see the [wiki:PlasticSlices/SliceStatus#Baseline5 Baseline 5] Slice Status. … … 173 176 Detailed Description: 174 177 175 Similar to the previous baseline, cause the experiment running in each slice to move at least 10 0MB/second continuously over the course of a 144-hour period.178 Similar to the previous baseline, cause the experiment running in each slice to move at least 10 MB/second continuously over the course of a 144-hour period. 176 179 177 180 The purpose of this baseline is to confirm that an experiment can send a higher volume of data continuously without interruption, for several days running. … … 179 182 Summary of overall results: 180 183 181 * ''To be added once the baseline finishes.'' 184 * We continued to use the same logging method, which didn't work as well, perhaps because of the huge size of the log files. 185 * All but one of the slices was able to send 10 Mb/s when things were going smoothly. 186 * A variety of outages occurred during this baseline, so things often weren't going smoothly. 187 * Despite these challenges, many slices successfully transfered data continuously for most of the duration of the bsaeline. 182 188 183 189 For more details, see the [wiki:PlasticSlices/BaselineEvaluation/Baseline6Details Baseline 6 Details] page. For an overview of slices, participants and experiments, see the [wiki:PlasticSlices/SliceStatus#Baseline6 Baseline 6] Slice Status. … … 203 209 Summary of overall results: 204 210 205 * ''To be added once the baseline finishes.'' 211 * We conducted two Emergency Stop tests, both involving resources at BBN. 212 * We accidentally left the experiments running after the Emergency Stop tests completed, which led to some odd results in the raw logs. 213 * We postponed the tests involving other sites, to incorporate lessons learned during these teasts. 206 214 207 215 For more details, see the [wiki:PlasticSlices/BaselineEvaluation/Baseline7Details Baseline 7 Details] page. For an overview of slices, participants and experiments, see the [wiki:PlasticSlices/SliceStatus#Baseline7 Baseline 7] Slice Status. … … 215 223 Detailed Description: 216 224 217 This baseline creates new temporary slices, rather than using the existing ten slices, creating a thousand slices at the rate of one slice per second, and then 218 continuing to delete and create a new slice every second, for 24 hours. Each slice will include resources at three campuses, selected randomly for each slice. Automated 219 tools will confirm that the resources are available, e.g. by logging in to a host and running 'uname -a'. 225 This baseline creates new temporary slices, rather than using the existing ten slices, creating a thousand slices at the rate of one slice per second, and then continuing to delete and create a new slice every second, for 24 hours. Each slice will include resources at three campuses, selected randomly for each slice. Automated tools will confirm that the resources are available, e.g. by logging in to a host and running 'uname -a'. 220 226 221 227 The purpose of this baseline is to confirm that many users can create slices and allocate resources at the same time. … … 223 229 Summary of overall results: 224 230 225 * ''To be added once the baseline finishes.'' 231 * We began by simply creating 10, 100, and 1000 slices in the pgeni.gpolab.bbn.com Slice Authority, without any resources (i.e. without creating any slivers). 232 * The first test worked fine, but 100 slices (at one per second) started to overwhelm the resources of the system providing the SA service, and 1000 slices completely overwhelmed it. 233 * We postponed the portions of this baseline that involved creating slivers. 226 234 227 235 For more details, see the [wiki:PlasticSlices/BaselineEvaluation/Baseline8Details Baseline 8 Details] page.
