If you have results, in some static form, you can dynamically mount NFS connections as needed to acces those directories.
Is your "backbone" 1GB or 10GB? If you can create a subnet for the fast NICs and each UNIX box has a 10GB NIC, this is very acceptable - what we do now. We create a job's data, notify the other box, it NFS mounts the dataset readonly, and away we go.
There is another issue to consider. Even though you may get great throughput, some boxes have issues. Solaris with older Qlogix cards takes a hit on interrupts. Because the cpu does a lot of work for the NIC.
All of this is a case of limiting factors, something you see in Science a lot. When you raise the bar on one limit (cpu) then some other resource becomes limiting (I/O in this case or interrupt stack). Since it is not economically feasible to build highways to completely handle rush hour traffic, so it is with computers. As long as it does not hurt production, and you get more processing power, you are okay. You did pay for the hadware, so use it.

NAME
svm-grid - a parameter selection tool for LIBSVM
SYNOPSIS
svm-grid [-log2c begin,end,step ] [ -log2g begin,end,step ] [ -v fold ] [ -svmtrain pathname ] [ -gnuplot pathname ] [ -out pathname ] [
-png pathname ] [ additional_parameters_for_svm-train ] dataset
DESCRIPTION
grid.py is a parameter selection tool for C-SVM classification using the RBF (radial basis function) kernel. It uses cross validation (CV)
technique to estimate the accuracy of each parameter combination in the specified range and helps you to decide the best parameters for
your problem.
FILES
See svm-train(1) for the format of dataset
EXAMPLES
svm-grid -log2c -5,5,1 -log2g -4,0,1 -v 5 -m 300 heart_scale
BUGS
Please report bugs to the Debian BTS.
