Hi Chris and other bioclusterers,

I just stumbled upon http://www.sistina.com/products_gfs.htm, which 
states that one advantage of GFS (combined with Mosix?) is that it

	"Eliminates NFS Bottlenecks," 

and as example these guys list
                      
  	"Life Sciences"

and

	"Shared BLAST databases."

Independently of the fact that these guys charge $1000/node (Am I 
correct?), I wonder if their claims are correct?  Can Mosix -- by using 
GFS -- really achieve a high I/O throughput?

A related question is: does Mosix work together with PVFS?

Best regards, Ivo

(1) My limited experience with MOSIX has me believing that in the MOSIX 
world a process that is doing heavy I/O operations will never get 
migrated across to a less loaded machine. This alone is enough for me 
to
not consider MOSIX/SSI for bioclusters because all of the ones I have 
built so far are very, very often used for IO-bound embarassingly 
parallel jobs (blast, genscan, etc. etc). Am I totally wrong? Anyone 
out
there using SSI/Mosix systems for hardcore biology stuff?
