 +===== 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.
 +You can see memory usage of your job using ''condor_q'' command (7th column
 +gives memory usage in MB).
 +You can check the node your job is running using ''condor_q -run''
 +You can check memory status in a node using ''ssh polyp6 "vmstat -s"''.
 +For more memory checking commands see
 +or google is your friend.
 +**Your job might get killed if it is using swap. Do not waste your
 +system administrators' time with this and force them to police the condor jobs.
 +Just control your jobs and submit jobs that are reasonable.**
