The Schrödinger Suite is a collection of software for chemical and biochemical use. It offers various tools that facilitate the investigation of the structures, reactivity and properties of chemical systems. There is a campus site license for this software, supported by UITS. More information is available here: http://software.uconn.edu/schrodinger/ .
It is recommended currently to use Schrodinger through an interactive session because of some issues encountered when submitting jobs through submission scripts.
Start an interactive session:
srun --x11 -N 1 -n 126 -p general --constraint=epyc128 --pty bash
Make sure to include the “--x11” flag for the GUI
Load Modules
Once a node is assigned to the interactive srun job in the previous section, schrodinger can be loaded from one of the various modules available on HPC.
module load schrodinger/2023-3
You can then see a list of executable programs:
find /gpfs/sharedfs1/admin/hpc2.0/apps/schrodinger/2023-3/ -maxdepth 1 -executable -type f -printf "%f\n" | sort | pr -tT -8 | column -t autots elements hppmap knime mxmd phase_qs qpld ska biolumin epik ifd lambda_d oned_scr phase_sc qsite ssp blast epikx ifd-md licadmin para_tes pipeline quick_sh sta bmin fep_abso impact ligand_s pfam prime run structur confgen fep_plus installa ligprep phase_bu prime_mm schrodin testapp confgenx fep_solu jaguar machid phase_da primex shape_sc vsw consensu ffbuilde jobcontr macromod phase_fi qikfit shape_sc watermap constant generate jsc maestro phase_fq qikprop shape_sc wscore covalent gfxinfo jws material phase_hy qiksim sitemap xtb desmond glide
You can also see a list of utilities with the same find command above:

Example Application Usage
qsite
qsite -SAVE -PARALLEL 24 3IIS_Per1.in
Note that the numeric value of -PARALLEL should match the numeric value of the -n declaration that you specified in the previous srun command.
Jaguar
jaguar run nameofinput.in
There is a way to target a specific Schrodinger application or utility with the following syntax:
Multisim example:
$SCHRODINGER/utilities/multisim < rest Of command options here >
You can then view the status of your running job with sacct.

Installation Oddities
Schrödinger comes pre-packaged with an outdated version of mpi(< 1.8.1), meaning an old bug in the MPI->SLURM interface needs to be manually patched by appending the following line to schrodinger's mpi's default config file:
plm_slurm_args = --cpu_bind=boards
Command to call a Schrodinger utility
