Status Report on the Development of the Interoperable Mpi Protocol

چکیده
| An industry lead eeort to create a protocol for the interoperation of implementations of the Message Passing Interface (MPI) has been ongoing since March of 1997. Meetings have been held several times per year with many implementors of MPI participating to help deene the Inter-operable MPI protocol (IMPI). This process has resulted in a simple protocol that can be incorporated into existing implementations of MPI to provide for interoperability. In this paper we describe IMPI along with some of the reasoning for its design. We also describe an IMPI tester, developed at NIST, that tests implementations for compliance to the protocol. The rst complete version of IMPI will be ready by the time this report is published and we expect IMPI compliant implementations of MPI to become available soon after.

The Interoperable Message Passing Interface (IMPI) Extensions to LAM/MPI
Interoperable MPI (IMPI) is a protocol specification to allow multiple MPI implementations to cooperate on a single MPI job. Unlike portable MPI implementations, an IMPI-connected parallel job allows the use of vendor-tuned message passing libraries on given target architectures, thus potentially allowing higher levels of performance than previously possible. Additionally, the IMPI protocol use...
متن کاملComparison of transient ischemic dilation ratios in SPECT and SPECT-CT myocardial perfusion imaging in the low pre-test probability group
Introduction: The main purpose of this study was to compare transient ischemic dilation (TID) ratios in SPECT-low dose CT and SPECT Myocardial Perfusion Imaging (MPI) by application of different quantitative programs and quantify the possible shift in the upper normal limits of TID ratio in the SPECT-CT MPI. Methods: 149 Patients with low pre-test probability for coronary artery disease (CAD),...

Introduction: The recent advances in information and communication technology have increased the possibility to store and circulate information. EHR (Electronic health record) system, as an IT (Information Technology) in the healthcare field, can improve access to patient data. International research studies show that the benefits of e-health are significantly greater where EHR information can ...
متن کاملCovid-19 manifestation on Tl-201 myocardial perfusion SPECT/CT
A 67 years old woman was referred to nuclear medicine center for myocardial perfusion imaging (MPI) for assessment of ischemic heart dieses (IHD).She had a history of atypical chest pain and dyspnea since about 10 days before admission. The MPI SPECT/CT was performed by stress/redistribution Tl-201 protocol. MPI was interpreted as relatively good coronary flow with no appreciable stress induced...
متن کاملThe Status of Stress Myocardial Perfusion Imaging Using 99mTc Pharmaceuticals in Japan: Results from a Nationwide Survey
Objective(s): To appropriately use one-day myocardial perfusion imaging (MPI) with 99mTc radiopharmaceuticals (i.e. to avoid shine-through artifacts), injection doses need to be optimized and dose ratios between the 1st and 2nd scans should be maintained at ≥ 3. However, the current state of practice in Japan is unclear. Thus, the aim of this study was to clarify the details of MPI protocols us...
