PNSC Clause Samples
The PNSC clause, which stands for "Particulars Not Separately Charged," defines how certain costs or charges are handled within a contract, specifying that some items or services are included in the overall price and will not be billed separately. In practice, this means that the contractor or supplier cannot submit additional invoices for these specified items, as their costs are presumed to be covered by the main contract sum. This clause ensures transparency and prevents disputes over unexpected or hidden charges, thereby providing cost certainty for the contracting parties.
PNSC. PSNC uses Global Parallel File System which is a popular, commercial cluster file system from IBM. This one-node installation of GPFS normally acts as the frontend of the Hierarchical Storage Management system. Data from GPFS are transparently migrated and recalled to and from tape system (2,5PB of LTO5 in IBM TS3500 library). However for the purposes of the current stage of federation scalability tests we were not migrating data to tapes, keeping all files in the GPFS disk cache. The disk cache itself is configured as 24 NSDs, approximately 1TB each, based on 240-drives IBM DS5300 disk array. The GPFS runs on the x3650 M3 server with two 12-core Intel Xeon X5650 2.67GHz CPUs and 32 GB RAM. The details of the test installation are available on the project wiki. The overall scheme of the testing infrastructure is presented on the picture below.
