I see that you submitted a bug report regarding 5-dimensional grid  
arrays in Cactus.  These are indeed not yet supported in PUGH.  4- 
dimensional grid arrays should already be supported, however.

You can use a work-around to obtain 5-dimensional grid arrays by using  
vector grid arrays.  The syntax of interface.ccl would be

cctk_real StressTensor[4] type=ARRAY size=64,64,64,4 dim=4  
ghostsize=1,1,1,0 Timelevels=1
{
    T_total
    T_mhd
}  "Stress Tensors"

This gives you four grid functions called T_total[0], ...,  
T_total[3].  These have contiguous storage, and can e.g. be accessed  
as one 5-dimensional array T_total(i,j,k,p,q) in Fortran.

(I have not actually tested this; I hope that this works!)

Dear Friends,

It is with the deepest sadness and regret that we inform you of the  
death of our close colleague and friend, Thomas Radke, who passed away  
suddenly last week in Potsdam, Germany.

Thomas was part of our team since 1999, when he joined the Albert  
Einstein Institute. Since then, Thomas has been an integral member of  
our extended group, contributing much of the current parallel and I/O  
layers of Cactus, but also adding so much more to the Cactus, Carpet,  
TiKSL, GriKSL, GridLab and D-Grid projects. Outside of these Thomas  
also contributed to the Linux Kernel providing the first  
implementation of symmetric multiprocessing support. Thomas had our  
greatest respect for his skills in programming, his knack for making  
things really work, his talent for problem solving, and his passion in  
working closely with his numerical relativity colleagues to achieve  
their scientific goals. Although his work has and continues to further  
scientific research around the world, Thomas only reluctantly accepted  
credit or recognition.

Thomas was also our friend. We will miss his smile, his attitude to  
life, and his caring nature. We will always remember him and our lives  
are better for having known him.

The Cactus Team
