+ | ===== Cluster Configuration ===== | ||
+ | |||
+ | |||
+ | In general, the cluster configuration should remain as " | ||
+ | |||
+ | Some general information gleaned from our anticipated user base: | ||
+ | |||
+ | * Software: mostly home grown code, C/C++ and Fortran programs (probably a Portland suite of compilers), Matlab (and MatlabMPI), AMBER, NAMD, CHARMM, and Gaussian. | ||
+ | |||
+ | * 64 bit compilations will be required, as is a 64-bit operating system with 32-bit backward compatibility | ||
+ | |||
+ | * Most application programs will be floating point and CPU intensive versus relatively few integer and data intensive applications | ||
+ | |||
+ | * A Linux operating system is required. | ||
+ | | ||
+ | * A ROCKS based implementation is preferrable with PBS as the scheduler (at least most users had experience with this). | ||
+ | |||
+ | * MPI will be required, preferably to as many work nodes as possible | ||
+ | |||
+ | * Any other cluster management tools for monitoring, administration, | ||
+ | |||
+ | ---- | ||
+ | |||
+ | Here is a rough hardware configuration guide ... | ||
+ | |||
+ | * 1 head node (Dual Intel 5148 processors, 2 GB RAM, mirrored 80 GB HD, 2 channel FC HBA) on private & public network | ||
+ | |||
+ | * 1 NFS node (Dual Intel 5148 processors, 2 GB RAM, mirrored 80 GB HD, 2 channel FC HBA) on private & public network | ||
+ | |||
+ | * 60 lightweight work nodes (Dual Intel 5148 processors, 2 GB RAM, single 80 GB HD (or smaller)) on private network | ||
+ | |||
+ | * 4 heavyweight work nodes (Dual Intel 5160 processors, 16 GB RAM, single 80 GB HD (or smaller)) on private network | ||
+ | |||
+ | * Sixteen of the lightweight work nodes should be interconnected via Infiniband for low latency. The rest should be interconnected via gigabit ethernet. | ||
+ | |||
+ | * Although local disk space is available, our NAS/SAN filesystems will provide the storage area for datasets and home directories | ||

+ | |||
+ | The quote should include all racks, power distribution, | ||
+ | |||
+ | We will want the equipment to be assembled, racked, and imaged by the vendor either onsite or prior to delivery (no preference). We will require 24/7/4hr support for the master and NFS nodes, and 24/7 support for OS/ | ||
+ | support will be sufficient for the compute nodes. The duration of all support should be three years. After | ||
+ | delivery/ | ||
