PetscErrorCode PetscBoxAuthorize(MPI_Comm comm,char access_token[],char refresh_token[],size_t tokensize)Not collective, only the first process in MPI_Comm does anything
| comm | - the MPI communicator | |
| tokensize | - size of the token arrays |
| access_token | - can be used with PetscBoxUpload() for this one session | |
| refresh_token | - can be used for ever to obtain new access_tokens with PetscBoxRefresh(), guard this like a password it gives access to your Box Drive |
You can run src/sys/webclient/tutorials/boxobtainrefreshtoken to get a refresh token and then in the future pass it to PETSc programs with -box_refresh_token XXX
This requires PETSc be installed using --with-saws or --download-saws
Requires the user have created a self-signed ssl certificate with
saws/CA.pl -newcert (using the passphrase of password)
cat newkey.pem newcert.pem > sslclient.pem
and put the resulting file in either the current directory (with the Section 1.5 Writing Application Codes with PETSc) or in the home directory. This seems kind of silly but it was all I could figure out.
