Parallel Quantum Solutions WHO ARE WE? Parallel Quantum Solutions (PQS) manufactures parallel computers with integrated software for high-performance computational chemistry. Our offerings have • an exceptional performance/price ratio • are fully configured for parallel computation straight out of the box. Our current product, the QuantumCube™, is aimed primarily at ab initio modeling, but we also offer semiempirical, molecular mechanics and dynamics methods. Our software enables the user to optimize chemical structures and transition states and to predict and display (now optionally including 3D Stereo) properties such as molecular orbitals, charge distributions, electrostatic potentials, vibrational modes and to simulate IR, Raman, VCD and NMR spectra. The high computational demand of ab initio calculations requires parallel processing to achieve reasonably fast turnaround. Our systems, based on personal computer technology, are fully competitive with expensive general purpose parallel computers (see our benchmarks) at a fraction of the cost. They are affordable by individual researchers or small groups. To ensure reliability, we use only high quality parts and technologies. Our systems come with the PQS suite of programs fully configured and ready to use. PQS was founded by Peter Pulay, Jon Baker and Krys Wolinski in 1997. 1 Parallel Quantum Solutions HARDWARE QuantumCube™ clusters Jobs involving large molecules, high levels of theory and many hundreds of basis functions are now commonplace. To meet these high demands all QuantumCube™ clusters are preconfigured for parallel operation and, in combination with the PQS software suite and preinstalled user accounts, are ready for use “straight out of the box.” In addition to our own software, the QuantumCubeTM comes with a wide range of freely available open source computational chemistry software which is installed by default, such as the PSI3 program for high accuracy calculations on small molecules and the NAMD parallel dynamics package. We have arrangements with several third-party software vendors to preinstall their programs at no extra charge other than the standard list price of the software. These include: • ADF/BAND • MolPro • COSMOtherm • Q-Chem • Jaguar • PCModel • Gaussian • Spartan We will make our best effort to preinstall any other packages you might require. 2 Parallel Quantum Solutions QuantumCube™ turnkey computational chemistry clusters are designed for office use. Standard 20 AMP power lines and residential-grade air conditioning are easily sufficient for optimal operation. Large, efficient 80 mm fans used in combination with straight- through air flow design reduce the heat and noise generated by the machines to below office acceptable levels. Its small size, low noise and relatively small heat footprint make the QuantumCube™ an attractive solution for individuals and small groups. All QuantumCube™ systems come preinstalled with a perpetual license to the full suite of PQS software. FEATURES QuantumCubeTM clusters are built using two types of chassis: one holding two dual-processor motherboards and the other holding four. With the multi-core processors available today, this gives us a range of from 24 to 96-CPUs per chassis. Larger clusters can be constructed using multiple chassis. 3 Parallel Quantum Solutions Each node in the QuantumCubeTM is configured with two 1 or 2 TB enterprise class drives using mirrored and striped RAID. This speeds up scratch disk access during calculations. All other partitions are mirrored for data integrity. Our standard configuration provides at least 2 GB of memory per CPU, with at least 4 GB per CPU in the advanced configuration. All QuantumCubeTM clusters are configured with the latest stable Linux OS, currently CentOS 5.5 (which is fully Red Hat Linux compatible) and a full set of Linux utilities, PQS cluster management tools, MPI and PVM parallel environments and the SGE queuing system. Additional queuing systems can be set up on request. All QuantumCube™ systems come preinstalled with a perpetual license to the full suite of PQS software. A set of customer-specified user accounts is preinstalled, so users can set up and submit jobs minutes after unpacking the unit. PQS cluster management tools simplify common cluster tasks such as powering up/down, adding users, changing passwords, monitoring node activity, managing the system clocks and data backup. Each QuantumCubeTM is shipped with a 23” LED monitor, keyboard & mouse, a USB backup drive and a gigabit network switch for models with more than two nodes. 4 Parallel Quantum Solutions MODEL OVERVIEW QuantumCubeTM clusters are equipped with up to 384 GB of RAM, 16TB of disk space, mirrored RAID scratch partitions, and up to 96 cores. We offer both Intel- and AMD-based systems incorporating the latest multi-core processors. # C R D R # C P A A i P c n s U o U M M o k r d / ( e c s t c G e y s l p o o s p B a r c e e ) c k e ( G ( ( G G Model B H B ) z ) ) QS24-2660C-XW6 24 2.66 48 2 4,000 2 Intel QS24-2930C-XW6 24 2.93 96 4 8,000 2 Intel QS48-2660C-XW6 48 2.66 96 2 8,000 4 Intel QS48-2930C-XW6 48 2.93 192 4 16,000 4 Intel QS32-2000C-OM8 32 2.00 64 2 4,000 2 AMD QS32-2400C-OM8 32 2.40 128 4 8,000 2 AMD QS64-2000C-OM8 64 2.00 128 2 8,000 4 AMD QS64-2400C-OM8 64 2.40 256 4 16,000 4 AMD QS48-1900C-OM12 48 1.90 96 2 4,000 2 AMD QS48-2200C-OM12 48 2.20 192 4 8,000 2 AMD QS96-1900C-OM12 96 1.90 192 2 8,000 4 AMD QS96-2200C-OM12 96 2.20 384 4 16,000 4 AMD We use the latest available hardware.

The stereo effect is achieved through the use of active shutter glasses operating at 120Hz refresh rate. The glasses are synchronized with the display, either a projector or a monitor, producing two distinct images, one for each eye. The visual effect is quite breathtaking and is far superior to the earlier technologies of passive polarized and anaglyph (red/blue) glasses. A number of scientific applications which use OpenGl libraries have been capable of displaying stereo images for several years; however the cost of the necessary hardware has until now been prohibitive. Our systems are preconfigured to run the stereo- enabled version of the PQS suite. Stereo-enabled PyMol is also installed. Additionally we offer support in installing third-party applications on our machines. MODELS StereoStationTM 2 person SS4-2800-I74-W2P Intended to be used as a small personal workstation, capable of executing serial PQS jobs and stereo visualization of the results for up to 2 people. 6 Parallel Quantum Solutions StereoStationTM 10 person SS4-2800-I74-W10P Intended for a classroom or research environment, capable of executing serial PQS jobs and stereo visualization of the results for up to 10 people. StereoQuantumStationTM 2 person SS16-2000-OM8-L2P Intended for use as a large scale workstation or add-on to an existing PQS QuantumCubeTM. A 16-core, 64 GB of memory Linux node, capable of running a large fully parallel PQS calculation. Results can be viewed in stereo by up to 2 people. 7 Parallel Quantum Solutions WARRANTY & SUPPORT We offer a full, 1 year warranty on all hardware components.
