To understand this approach, it would be useful to describe the type of system which is to be built. It is evident that many of the system characteristics will be prescribed by the application, others will be purely a matter of personal choice. The essential characteristics are few in number and must not be confused with the non-essential characteristics. The remainder of this paper presents a set of do-it-yourself instructions for designing your own multi-processor system which stresses the essential characteristics. The intent being that the reader can follow through these instructions and design his own system for his own particular application. In this way, each reader can have a specific system in mind which he can evaluate critically. Although there would be individual differences in the systems under consideration by different individuals, the essential characteristics would be the same, and discussion would then tend to center about these essential features. The paper concludes with a summary in which the design approach is reviewed in an attempt to emphasize the utility of the approach.","PeriodicalId":127219,"journal":{"name":"AFIPS '67 (Spring)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127455635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These applications have shown that mass storage can dramatically reduce requirements for main storage and at the same time improve system performance.

Barry inserted a glass bulb into the jugular vein of a horse and observed that when the animal was standing the blood flowed intermittently in jets that were not synchronous with either respiratory or heart rates (Brecher). Holt in 1941 arranged a flow circuit where the fluid traversed an interposed segment of collapsible tube and where he could vary at will the ratio of internal pressures. He observed that when the ratio approached zero the tube collapsed and began to pulsate. Brecher in 1952 examined carefully this phenomenon by decreasing the downstream pressure in the vena cava of open chest dogs and concluded that it originated in a momentary complete collapse of a segment of the vein when the extravascular (atmospheric or tissular) pressure exceeded the intravascular pressure. The continuous inflow of blood from the capillaries would then elevate again the intravascular pressure forcing the closed segment of vein to reopen. With repetition of the cycle the vein oscillated at frequencies and amplitudes whose complex relationships he studied in physical analogues made of collapsible rubber tubes. Furthermore, he pointed out the clinical significance of this \"chatter\" during cardiopulmonary bypass surgery when the collecting reservoir for venous return is positioned at an excessively low level. In 1953 Robard and Saiki and in 1955 Robard reported detailed studies on flow through collapsible tubes and on the clinical implications of its instabilities in relation to apparently anomalous flow-pressure patterns in various vessels of the body. Our own studies on the effect of quiet respiration in a two-chamber-hepatic valve model of venous return indicate that in the intact (closed chest) dog and man the venae cavae operate at the limits of equilibrium and that instability may develop during vigorous respirations.","PeriodicalId":127219,"journal":{"name":"AFIPS '67 (Spring)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1967-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130413334","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
