CCL:RE: FlexX und SGE

Hello Dirk,
 we recognized that it is actually a problem to combine
 FlexX and batch queuing systems (BQS) like for example
 SGE, because FlexX uses PVM for parallel computing.
 PVM set s up a separate control flow that conflicts
 with any BQS.
 Thus we developed a small tool called Distributor that
 allows for setting up parallel FlexX jobs without PVM
 that employs a BQS, e.g. SEG.
 The Distributor is a generic tool that can be applied
 to anycommand line based tool like for example FlexX.
 The only requirement is that the tool takes as input
 an ASCII file that contains the input for several runs
 of the tool and that this file can be split by rules
 (e.g. multi-mol2 ligand files for FlexX-Dockings).
 The Distributor splits the input files and creates for
 each batch a separate working environment and calls a
 job in the BQS to process the batch. The BQS is than
 responsible for the job scheduling. So there is only
 one control instance.
 After the jobs are done, the Distributor gathers the
 ASCII output of all jobs and cats this to one output
 file automatically (e.g. the predicted scores of FlexX).
 In addition, the Distributor can do some basic job
 statistic and report this optionally by email.
 If the called tool (e.g. FlexX) is able to call a
 callback script after each run, the distributor
 is also able to restart failed jobs with the item
 following the failed one.
 The split functions can be defined by the user.
 Split functions for mol2, sdf, and for splitting
 ASCII files by pattern or by counting are pre defined.
 The Distributor works with several BQS.
 It is tested with SEG and OpenPBS.
 If this sound interesting to you I would be happy
 to send you more details on the Dirtsibutor.
 Regards,
 Holger
