#573 | Fixed | Allocation of quadratic tracer indices | ||
Description |
The indices for time-averaged quadratic tracers need to be allocate of size MT instead of NAT in mod_ncparam.F allocate ( iHUTav(MT) ) allocate ( iHVTav(MT) ) allocate ( idTTav(MT) ) allocate ( idUTav(MT) ) allocate ( idVTav(MT) ) Many thanks to Mark Hadfield for reporting this bug. |

#574 | Done | Modified grep syntax in build scripts | ||
Description |
Changed the grep syntax in all build script which evaluates a Perl regular expression. This syntax is different in various operating system and we may get errors. In build.sh we now have: if (`echo $1 | grep '^[0-9]\+$'` != "" ) then ... endif instead of if (`echo $1 | grep -P '^\d+$'` != "" ) then ... endif In build.bash we now have: test=`echo $1 | grep '^[0-9]\+$'` instead of test=`echo $1 | grep -P '^\d+$'` Notice that both the plot and test repositories are also updated. |

#575 | Done | Added Hessian Drivers | ||
Description |
Added new drivers to compute singular vectors and stochastic optimals:
The associated propagators are:
The Hessian algorithms require the Lanczos vectors generated by any of the 4D-Var algorithms, which is stored in the adjoint output file. That is, we need to run any of the 4D-Var algorithms first. All these algorithms will be described in a publication in the near future. They are complex and requires a lot of expertise. Many thanks to Andy Moore for helping us to design and code these algorithms. They are released now because of substantial changes and corrections to the GST drivers. Currently, we are testing these algorithms and tracking couple of parallel issues with the Hessian Stochastic Optimals algorithm. |
