Dear all,
recently i installed the NWCHEM 6.3 on my PC
(CPU: i7-3770K, 32G RAM, 2T disk, OS: UBUNTU 12.04 (64 bit), Openmpi:1.6.5, Ifort & Icc: 13.1.3 ).
When i run "top" i found the process of NWCHEM are either R or D, for the later, GOOGLE says "Processes in a "D" or uninterruptible sleep state are usually waiting on I/O. " i also found the "ubinterruptible sleep" on my clusters ( RHEL 5.7 and CENT OS 6.3.)
What the bottleneck, should i change the SATA disk as SAS or SSD? And how to avoid it for the clusters, should i add an I/O cluster?
Thanks for your response.
