Currently, kernel names are specified via hardwired parameter lists.\r\n\r\nIf no one objects, I will go ahead and submit one or two pull request that include the following two changes:\r\n\r\n* make smoothing and summing utilities share a consistent command line interface\r\n\r\n* allow smoothing and summing utilties to act on multiple elastic parameters by accepting comma delimited list of kernel names\r\n\r\nAs another benefit, the cost of smoothing operations could be reduced by making smooth_sem work on multiple material parameters (as per Daniel's comments).  The second change above constitutes a step in this direction.\r\n\r\nThis issue applies to both SPECFEM3D and SPECFEM3D_GLOBE.\r\n"},"comment":{"url":"https://api.github.com/repos/geodynamics/specfem3d/issues/comments/75496284","html_url":"https://github.com/geodynamics/specfem3d/issues/419#issuecomment-75496284","issue_url":"https://api.github.com/repos/geodynamics/specfem3d/issues/419","id":75496284,"user":{"login":"rmodrak","id":4483402,"avatar_url":"https://avatars.githubusercontent.com/u/4483402?v=3","gravatar_id":"","url":"https://api.github.com/users/rmodrak","html_url":"https://github.com/rmodrak","followers_url":"https://api.github.com/users/rmodrak/followers","following_url":"https://api.github.com/users/rmodrak/following{/other_user}","gists_url":"https://api.github.com/users/rmodrak/gists{/gist_id}","starred_url":"https://api.github.com/users/rmodrak/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/rmodrak/subscriptions","organizations_url":"https://api.github.com/users/rmodrak/orgs","repos_url":"https://api.github.com/users/rmodrak/repos","events_url":"https://api.github.com/users/rmodrak/events{/privacy}","received_events_url":"https://api.github.com/users/rmodrak/received_events","type":"User","site_admin":false},"created_at":"2015-02-23T06:54:17Z","updated_at":"2015-02-23T06:54:17Z","body":"Hi Dimitri,\r\n\r\nThanks for pointing that out.  I was a little confused about the make system.  I added the new routines to src/tomography/rules.mk, but not Makefile.in.  Let me correct that.\r\n\r\nRyan"}}
