2 – InfiniPath Cluster Administration Performance and Management Tips

Q

2.10.6

Hyper-Threading

If using Intel processors that support Hyper-Threading, it is recommended that HyperThreading is turned off in the BIOS. This will provide more consistent performance. You can check and adjust this setting using the BIOS Setup Utility. For specific instructions on how to do this, follow the hardware documentation that came with your system.

2.10.7

Homogeneous Nodes

To minimize management problems, the compute nodes of the cluster should have very similar hardware configurations and identical software installations. A mismatch between the InfiniPath software versions may also cause problems. Old and new libraries should not be run within the same job. It may also be useful to distinguish between the InfiniPath-specific drivers and those that are associated with kernel.org, OpenFabrics, or are distribution-built. The most useful tools are:

ipathbug-helper ipath_control rpm

mpirun ident strings ipath_checkout

NOTE: Run these tools to gather information before reporting problems and requesting support.

ipathbug_helper

The InfiniPath software includes a shell script ipathbug-helper,which can gather status and history information for use in analyzing InfiniPath problems. This tool is also useful for verifying homogeneity. It is best to run ipathbug-helperwith root privilege, since some of the queries require it. There is also a --verboseoption which greatly increases the amount of gathered information. Simply run it on several nodes and examine the output for differences.

ipath_control

Run the shell script ipath_control as follows:

%ipath_control -i
