Error in { : task 2 failed - "error code 2 from Lapack routine 'dsyevr'" #800

Hello!

I have been running some simulations in parallel with R and I got this error:

Error in { : task 2 failed - "error code 2 from Lapack routine 'dsyevr'"

I believe the problem would be in a function that gets called by the script running in parallel. This is a function that finds the low-rank approximation of a matrix A.

lra_svt<-function(A, k.hat,p){ A.svd<-svd(A) d.new<-A.svd$d d.new[(k.hat+1):length(A.svd$d)]<-rep(0,times=(length(A.svd$d)-k.hat)) PA<-A.svd$u%%diag(d.new)%%t(A.svd$v) PA<-PA/p return(PA) }

Do you know how I can overcome this problem?

(Please let me know if you would like me to submit more code information- I am a bit new in to that)

Thank you! Andriana (Please let me know if you would like me to submit more code information- I am a bit new in to that)

Hi. INFO > 0 means Internal error. So, my first guess is that dsyevr couldn't complete the task. Did you try to experiment with different matrices to see if the problem still remain?
