Error in mcfork() #129

Closed CloudRidingCavalier closed 2 years ago

CloudRidingCavalier commented 4 years ago

To whom it may concern,

Recently I performed a CITRUS analysis with 328 samples, and for each sample, 20000 events were extracted and the clustering cutoff was set to 1%. After 5-folds cross-validation steps were done, I received the following error message:

Clustering 5238574 events Clustering 5240000 events Clustering 5238574 events Clustering 5258574 events Clustering 5258574 events Mapping 1320000 events Error in mcfork() : unable to fork, possible reason: Cannot allocate memory Calls: citrus.full ... citrus.mapToClusterSpace -> mclapply -> lapply -> FUN -> mcfork Execution halted

I did some researches online yet I have no clear clue about what this message means. Thus I would be deeply grateful if someone could help me to figure out this issue.

Thanks,

Alex

Sounds like you're out of RAM?

Hi Robert,

Thanks for your quick reply. I believe we have sufficient RAM since this job was running on a 24-cores cluster. May I kindly ask how I could overcome this issue?

Best,

Alex
