46 | == Running NEMO5 Jobs on RCAC from nanoHUB == | |||
47 | ||||
48 | !NanoHUB users of NEMO5 can take advantage of the computing power of the Rosen Center for Advanced Computing (RCAC). Users can submit jobs from their nanoHUB workspaces to run on the RCAC clusters. The input files are located in the user's nanoHUB workspace, the job is submitted and run on RCAC, and the output files are written back to the user's nanoHUB workspace. It is not necessary to compile NEMO5 or to download the executable. The materials database and an input file are required. | |||
49 | + | |||
50 | + | !NanoHUB workspace: http://nanohub.org/tools/workspace
|
||
51 | ||||
52 | Materials database: https://nanohub.org/resources/13606 | |||
53 | ||||
54 | Sample input files: https://nanohub.org/resources/13410 | |||
55 | ||||

+ | 1. The most recent revision of NEMO5 on RCAC (Rossmann system) for use by nanoHUB workspace is 17881. Replace 'XXXXX' below with this number.

60 | {{{ | |||
61 | - | ln -s /apps/share64/ |
+ | ln -s /apps/share64/debian7/nemo/17881/mat/all.mat
|
62 | }}} | |||
63 | ||||
64 | Regardless of where you have the all.mat file located locally, the "database" line in the input file needs to be | |||
65 | {{{ | |||
66 | database = ./all.mat | |||
67 | }}} | |||
68 | ||||
69 | 3. Use the submit command to request a job to run on the RCAC machines. You can find out more information about the submit command using: | |||
70 | ||||
71 | {{{ | |||
72 | submit --help | |||
73 | }}} | |||
74 | ||||
75 | ||||
76 | 4. A typical job submission command is shown below. This particular example is located in the workspace in | |||
77 | /apps/share64/nemo/examples/current/public_examples/bulk_!GaAs_band_structure | |||
78 | ||||
79 | {{{ | |||
80 | - | submit -v |

|
81 | }}} | |||
82 | - | Here, the computer system |
+ | Here, the computer system rossmann is the venue where the job will execute. The materials database (all.mat) is passed with the '-i' flag. The line ends with the name of the nemo executable and the input file.
|
83 | ||||
84 | - | Available venues right now are coates and rossmann
|
||
85 | ||||
86 | For instance, if the materials database file is in a separate directory, the command may look something like | |||
87 | {{{ | |||
88 | - | submit -v |
+ | submit -v rossmann -i ./all.mat nemo-rXXXX GaAs_sp3d5sstar_SO_Klimeck.in
|
89 | }}} | |||
90 | ||||
91 | After the job runs, output files will be written back to your nanoHUB workspace directory where you submitted the job. | |||

+ | 5. (Under construction) Larger simulations can be run on multiple cores. The total number of cores '-n' and wall time '-w' can specified. For '-N', Rossman has 24 cores per node. See the "Partitioning" section (4.2.4) of the NEMO5 manual.
|
94 | ||||
95 | The submit command takes arguments related to the number of processors and walltime required. | |||
96 | ||||
97 | {{{ | |||
98 | submit --help | |||
99 | }}} | |||
100 | ||||
101 | The relavent arguments are | |||
102 | {{{ | |||
103 | -n NCPUS, --nCpus=NCPUS Number of cores for MPI execution | |||
104 | ||||
105 | -N PPN, --ppn=PPN Number of cores/node for MPI execution | |||
106 | -w WALLTIME, --wallTime=WALLTIME | |||
107 | }}} | |||
108 | ||||
109 | - | The following job requests |
+ | The following job requests 24 cores on Rossmann for 5 minutes (the example below is located in public_examples/bulk_!GaAs_parallel)
|
110 | ||||
111 | {{{ | |||
112 | - | submit -v |
+ | submit -v rossmann -i ./all.mat -n 24 -w 0:05:00 nemo-rXXXX bulkGaAs_parallel.in
|
113 | }}} | |||
114 | ||||
115 | This will request 16 cores on two nodes | |||
116 | {{{ | |||
117 | - | submit -v |
+ | submit -v rossmann -i ./all.mat -n 48 -N 24 -w 0:05:00 nemo-rXXXX bulkGaAs_parallel.in
|
118 | }}} | |||
119 | If the request is for more than one total node, the request must be for the total number of cores on the nodes. In other words, one cannot have | |||
120 | {{{ | |||
121 | - | -n |

|
122 | }}} | |||
123 | However, one can have | |||
