This code and instructions were tested to work on pleiades with checkpoint65v
There is something not quite right about checkpoint65v dumpfreq output.
For example, 2D output files are 421080 instead of 421200 long.

1 dimitri 1.1 Right now some sizes need to be configured manually:
2    
3     recvTask.c lines 79-82
4    
5 dimitri 1.2 #define NUM_X 90
6     #define NUM_Y 1170L // get rid of this someday
7     #define NUM_Z 50
8 dimitri 1.1 #define MULTDIM 7
9    
10    
11     and
12    
13     readtile_mpiio.c lines 115-119
14    
15 dimitri 1.2 facetElements1D = 90;
16     tileSizeX = 30;
17     tileSizeY = 30;
18 dimitri 1.1 xGhosts = 8;
19     yGhosts = 8;
20    
21     One tile per rank is recommended, mostly for pickup input performance,
22     but it is not strictly necessary.
23    
24     Choose dumpFreq and pChkptFreq as usual. We're not set up
25     to do the rolling checkpoints yet. It'll dump u,v,t, and etan now -
26     send me a list of other fields you want, as it is rather involved
27     to change them. But this should be enough to see if it works.
