We present a system that allows OpenMP programs to execute on a network of workstations with a variable number of nodes. The ability to adapt to a variable number of nodes allows a program to take advantage of additional nodes that become available after it starts execution, or to gracefully scale down when the number of available nodes is reduced.

Both locally advanced adenocarcinoma of the stomach and gastro-esophageal junction are associated with poor prognosis due to the lack of effective treatment. Recently multimodal treatment consisting of neoadjuvant chemotherapy in combination with radiotherapy is reported to improve survival when compared to surgery alone. Neoadjuvant therapy in these(More)
18 Background: Insulin-like growth factor (IGF)-1, -2 and insulin-like growth factor binding proteins (IGFBP) are involved in the proliferation and differentiation of cells. It has never been evaluated if the IGF-system can serve as a tumor marker in neoplasms. METHODS In our prospective study, 163 patients with colorectal cancer (22), prostate cancer(More)

We p r e s e n t a system that allows task parallel OpenMP programs to execute on a network of workstations (NOW) with a variable number of nodes. Such adaptivity, generally called adaptive parallelism, is important i n a m ulti-user NOW e n vironment, enabling the system to expand the computation onto idle nodes or withdraw from otherwise occupied nodes.(More)
Patients with ESCC (squamous cell carcinoma of the esophagus) are most commonly diagnosed with locally advanced tumor stages. Early metastatic disease and late diagnosis are common reasons responsible for this tumor's poor clinical outcome. The prognosis of esophageal cancer is very poor because patients usually do not have symptoms in early disease stages.(More)
