PBS, refresh stdout

阅读更多关于 PBS, refresh stdout

问题 I have a long running Torque/PBS job and I'd like to monitor output. But log file only gets copied after the job is finished. Is there a way to convince PBS to refresh it? 回答1: Unfortunately, AFAIK, that is not possible with PBS/Torque - the stdout/stderr streams are locally spooled on the execution host and then transferred to the submit host after the job has finished. You can redirect the standard output of the program to a file if you'd like to monitor it during the execution (it makes

I need to copy a file x.dtsx from location a to location b. If x.dtsx already exists in b then I need to rename x.dtsx to x_Standby.dtsx Then, after renaming copy x.dtsx to b My current code looks like this: if exists %1 rename %1 %(should be 1_standy.extension) xcopy %1 %2 If you use the Command Processor Extensions (which is default on Windows 2000 and later) then you can use the following optional syntax: %~1 - expands %1 removing any surrounding quotes (") %~f1 - expands %1 to a fully qualified path name %~d1 - expands %1 to a drive letter only %~p1 - expands %1 to a path only %~n1 -

Use slurm job id

阅读更多关于 Use slurm job id

When I launch a computation on the cluster, I usually have a separate program doing the post-processing at the end : sbatch simulation sbatch --dependency=afterok:JOBIDHERE postprocessing I want to avoid mistyping and automatically have the good job id inserted. Any idea? Thanks You can do something like this: RES=$(sbatch simulation) && sbatch --dependency=afterok:${RES##* } postprocessing The RES variable will hold the result of the sbatch command, something like Submitted batch job 102045 . The construct ${RES##* } isolates the last word (see more info here ), in the current case the job id

How do I get the error level of commands in a pipe in Windows batch programming?

阅读更多关于 How do I get the error level of commands in a pipe in Windows batch programming?

问题 Batch files return the error code of the last command by default. Is it somehow possible to return the error code of a former command. Most notably, is it possible to return the error code of a command in a pipe? For example, this one-line batch script foo.exe returns the error code of foo . But this one: foo.exe | tee output.txt always returns the exit code of tee , which is zero. 回答1: I had a similar problem and settled on the following solution as I did not need to detect the exact error

What's the equivalent of Python's Celery project for Java?

阅读更多关于 What's the equivalent of Python's Celery project for Java?

I am trying to find an equivalent of Celery project for Java environment, I have looked at Spring Batch, but are there any better alternatives for distributed task queues. Thanks. Adam Gent What Celery is doing is very much akin to EIP , and SEDA with convenient task scheduling... (all you have left to do is add some DB, and async HTTP networking and you have got a complete enterprise quality stack). Basically in Java there is the Spring way, the Java EE way, and the Hadoop way: Spring: Spring Integration + Spring Batch + RabbitMQ Java EE: Mule + Quartz or EJB Scheduling + HornetMQ Hadoop:

Creating multiple videos with Avisynth

阅读更多关于 Creating multiple videos with Avisynth

问题 I have a bunch of individual files that I want to each run through Avisynth. However, an AVS file can only create one video. As far as I know, there is no way to declare a variable's value from the command line. I know that you can probably create a script that generates a bunch of AVS files and then somehow convert each AVS file to a video. However, since Avisynth is a scripting system, this seems kind of complicated. There must be some way to run different videos through a script, right?

C# mongodb driver 2.0 - How to upsert in a bulk operation?

阅读更多关于 C# mongodb driver 2.0 - How to upsert in a bulk operation?

问题 I migrated from 1.9 to 2.2 and reading the documentation I was surprised to discover that is not possible to upsert during a bulk operation anymore, since operations don't allow options. bulkOps.Add(new UpdateOneModel<BsonDocument>(filter, update)); collection.BulkWrite(bulkOps); Should be options.isUpsert = true; bulkOps.Add(new UpdateOneModel<BsonDocument>(filter, update, options)); collection.BulkWrite(bulkOps); Is this work in progress, intended, or I'm missing something? Thank you. 回答1:
