+ * We can specify the smpi latency/bandwidth factor with command line
+ add --cfg=smpi/bw_factor:"threshold0:value0;...;thresholdN:valueN"
+ or add --cfg=smpi/lat_factor:"threshold0:value0;...;thresholdN:valueN"
+ You can also use the "config tag" from platform file by adding this line
+ <prop id="smpi/bw_factor" value="threshold0:value0;...;thresholdN:valueN"></prop>
+ (see "example/platforms/tag_config.xml" to use "config tag").
+ Note that the command line supersedes the platform file configuration.
+ * Change the correction factors used in LMM model, according to
+ the lastest experiments described in INRIA RR-7821.
+ Accuracy should be improved this way.
