Dear Lapack Team,
I have a question concerning internal restrictions according to the
size of the matrices.
I am using SSYEVX and my code works well with matrix dimensions up to
30000x30000 using real*4 (less than 4GB memory).
I have tried to enlarge the dimension to 50000 or 70000. After approx.
10 hours calculation after calling SSYEVX the only result is a
segmentation fault. I expected the need of about 12 to 20 GB RAM. Are
there any restrictions?
I am using a node of a compute cluster with 256 GB RAM, AMD Opteron
processor and CentOS 64bit Linux system. Below you can see an extract
of my program.
Thank you in advance. I am looking forward to read from you. I really
could need some help.
