+ | ===== Condor Jobs Memory Usage ===== | ||
+ | Please check status of your condor jobs regularly, especially memory usage. | ||
+ | Each polyp node has 16 processors and 32 GB memory. This means 1 process | ||
+ | gets 2 GB memory in average. | ||
+ | |||
+ | When a polyp node is out of memory it starts using hard drive (swap) as memory | ||
+ | but reading and writing from hard drives is 1000 times slower. This means | ||
+ | if your jobs are using large amounts of memory and the polyp node processing | ||
+ | your job is out of memory, do not expect your job to terminate. | ||
+ | |||
+ | Tips: | ||
+ | You can see memory usage of your job using '' | ||
+ | gives memory usage in MB). | ||

+ | You can check the node your job is running using '' | ||
+ | |||
+ | You can check memory status in a node using '' | ||
+ | For more memory checking commands see http:// | ||
+ | or google is your friend. | ||
+ | |||
+ | **Your job might get killed if it is using swap. Do not waste your | ||
+ | system administrators' | ||
+ | Just control your jobs and submit jobs that are reasonable.** | ||
