1 SAMCEF for Wind Turbines Chapter 5 : Annex - Remote runs using Condor This document is the property of SAMTECH S.A. Samcef for Wind Turbines, Chapter 3, page 1

2 Table of contents of chapter 5 This document is the property of SAMTECH S.A. Samcef for Wind Turbines, Chapter 3, page 2

3 CONDOR: Distributed POOL job requests CENTRAL MANAGER job distribution This document is the property of SAMTECH S.A. Samcef for Wind Turbines, Chapter 3, page 3

4 CONDOR: Distributed POOL S N N N job requests job distribution N CM CENTRAL MANAGER Basics of Condor: a machine (S) submits a job to the central manager (CM) CM matches job requirements with available pool nodes and selects a node (N) CM manages file transfer from S to N N runs the computation, generating result files CM manages result transfer from N to S This document is the property of SAMTECH S.A. Samcef for Wind Turbines, Chapter 3, page 4

5 CONDOR for S4WT POOL S R: Sandbox CM CENTRAL MANAGER Specific S4WT (CAESAM): intermediate sandbox (R) Data copied from S to R: N Data copied from R: to N Results copied from N to R: Results copied from R: to N S4WT can be closed If R: is a network disk, laptops can be unplugged.

6 Running jobs This document is the property of SAMTECH S.A. Samcef for Wind Turbines, Chapter 3, page 6

7 Running jobs When the job is completed: Merge to retrieve the results This document is the property of SAMTECH S.A. Samcef for Wind Turbines, Chapter 3, page 7

8 Running jobs Auxiliary tools (in S4WT installation directory): condor_queues.cmd List user s submitted jobs condor_status.cmd List queue status condor_kill.cmd kill a job (same as the Kill button) This document is the property of SAMTECH S.A. Samcef for Wind Turbines, Chapter 3, page 8

9 Customization Sandbox definition in (installation directory)/s4wt_envi.cmd: set CAESAM_JOB_WD=csm:userhome ( %HOMEDRIVE%%HOMEPATH%) Caution: must be an URL: do not forget the file: protocol. set CAESAM_JOB_WD=file:u:/users/myname This document is the property of SAMTECH S.A. Samcef for Wind Turbines, Chapter 3, page 9

10 Customization Configuration file for all hosts in the network Fundamental because CONDOR creates temporary users without any environment! S4WT.env default file in (installation dir)/plugins/com.samcef.s4wt can be overwritten by (user home dir)/s4wt.env Contains sections by host: : hostname var = value var = value First section defines default variables: : default var = value var = value This document is the property of SAMTECH S.A. Samcef for Wind Turbines, Chapter 3, page 10

11 Customization Configuration file Compulsory variables Variable S4WT_ROOT SAMTECH_LICENSE_FILE TEMP Other variables Definition location of the installation directory on the remote computer path to the license file or server path to the temporary file directory. Remember that S4WT does not accept spaces in this path Variable Definition MKL_SERIAL no/yes: use or not local parallelism in matrix operations. default = no. It is advised to set it to yes if the computer has only 2 processors. OMP_NUM_THREADS S4WT_LOG_VERBOSITY If MKL_SERIAL is no, how many processors are to be used. Default = maximum available on the host. verbosity of the run. Can be HIGH, MEDIUM, LOW or SILENT. This document is the property of SAMTECH S.A. Samcef for Wind Turbines, Chapter 3, page 11

12 Customization Configuration file Example #============================================= : default #============================================= SAMTECH_LICENSE_FILE = 27009@flexlm TEMP = C:\SamWork S4WT_LOG_VERBOSITY = HIGH S4WT_ROOT = c:\samcef\s4wt\v2.0-05\ # #============================================= : pctiers S4WT_ROOT = c:\s4wt\v2.0-05\ #============================================= : pcabc S4WT_ROOT = Z:\Samcef\S4WT\V #============================================= : pc1234 S4WT_ROOT = Z:\Samcef\S4WT\V TEMP = D:\Tmpdir #============================================= This document is the property of SAMTECH S.A. Samcef for Wind Turbines, Chapter 3, page 12

13 Customization Configuration file If all installations are identical: #============================================= : default #============================================= SAMTECH_LICENSE_FILE = 27009@flexlm TEMP = C:\SamWork S4WT_LOG_VERBOSITY = HIGH S4WT_ROOT = c:\samcef\s4wt\v2.0-05\ # This document is the property of SAMTECH S.A.
