HPC Administration Interview Question.

1)How to create queue in pbs.(How to remove the nodes from the pbs).
2)Luster Module (Component(mgs,mds,mdt,oss,ost, & how to create the Luster file system).
3)HPL Benchmark attributes value.
4)pxeboot Different Stages.
5)./configure different option(--prefix=,--bindir=DIR,--sbindir=DIR,LDFLAGS="-L/LIBRARYPATH" CPPFLAGS="-I/INCLUDEPATH/")
6)Install OFED Driver & Command(ibstat,ibdiagnet)
7)How To improve the application performance.(Different Compiler option,File system(NFS,LUSTER),Change the network interface).
/mpirun -env I_MPI_FABRICS dapl/tcp 2 --hostfile hosts
(optimize for maximum speed)Optimization -O3,-O1,-O2
8)what is IPoIB (IP over Infiniband network)
OFED stack allows you to run TCP/IP over infiniband network.
Allow to run non-infiniband aware application across the network.
9)HPC component with priority.Hardware Components.
Monitor,Mouse,Keyboard,Computer Data Storage,Hard disk drive,
Graphics card,sound card,memory,meotherboard
Combination of H/W and S/W form a usable computer system.
10)what is the CPU processor family.(Example CMMACS- HPC)
HP Cluster Platform 3000 BL460c (Dual Intel Xeon 2.6 GHz eight core E5-2670 w/Infiniband FDR.
File System : ExaScaler 1.6.0 package with Lustre 2.1.3 parallel filesystem
