Installing TCE

Installing Un-fused Code Generator
To get the unfused code, go to the main branch(tag:release-08012005),
Select an Input File
Input file:
- spin-adapted ccd: ccd_adapted.eq
- spin-adapted ccsd: ccsd_adapted.eq
- spin-orbital ccd: ccd_orbital.eq
- spin-orbital ccsd: None
- spin-adapted ccsdt: None
- spin-orbital ccsdt: None
Select Compiler Flags
Compile option: -o3 -m0 --symmetry
Select Debugging Options
If you want to generate code with debug info(print some intermedaite result in computation), go to edu/ohio_state/cis/tce/symmetry, set the variable debugInfo as true in AllSymCodeGen.java. Otherwise, set it to false.
Edit Generated Code for Dense Mode operation
The current TCE system can't generate correct dense code. I first generate code without --symmetry option, then manually change it.
Copy perm files
The compiler will not only generate Fortran code, also only perm files
for intermediate arrays. You need to copy all perm files generated with code to execution directory.
Installing fused Code Generator
To get the fused code, go to the fusion branch(tag:fusion_20061228)
Select Input File
- spin-adapted ccd: ccd-sym-disk.eq
- spin-adapted ccsd: ccsd_marcel-disk.eq
Select Compiler Flags
Compile option: -o4 -m1 -t1 -f1 --symmetry -nonfusiontiling
Select Debugging Options
If you want to generate code with debug info, go to edu/ohio_state/cis/tce/symmetry, set Util.debugInfo in CodeGen.java and debugInfo in Util.java as true. Otherwise, set them to false.
Notes
The fused code doesn't include perm info. There is no perm files for fused code.
Tips
Tip 1: source files
Some programs have different implemental versions. I save these different versions in $NWCHEM/src/tce/back, when you want to run a special version, you need to copy the file to $NWCHEM/src/tce and compile it. For example, all spin-adapted ccd programs are ccd_sym.F. If you want to use the non-fusion version, copy $NWCHEM/src/tce/back/ccd_sym.nonfused.spin_adapted.F to $NWCHEM/src/tce/ccd_sym.F.
Tip 2: driver
There are some variables in the ohio_tce_reformat.F, you need to change them for different execution situations.
(1) spinmode
if you want to run spin-adapted code, set spinmode=1 if you want to run spin-orbital code, set spinmode=2
(2) maxiter: The maximal iteration for converge
Tip 3: perm
The non-fusion codes need perm files in execution. You can find the corresponding perm files in $NWCHEM4.7/bin/LINUX64/perm. You need to copy these files to execution directory for execution.
Tip 4: OTCE
To run non-fusion code, install the OTCE library by $NWCHEM/src/tce/otce/GNUmakefile.nonfusion. To run fusion code, install the OTCE library by $NWCHEM/src/tce/otce/GNUmakefile.fusion. Thus, you need to reinstall the OTCE library each time switching between fusion and non-fusion code.
Tip 5: input
The input files can be found in $NWCHEM4.7/bin/LINUX64/input. Note that, for spin-adapted and spin-orbital programs, you need different input files. For fusion and non-fusion programs, you can use the same input file.
